1 Final publishable summary report 1.1 Executive summary Investment in the development of next generation optical access technologies will enable a future network to be deployed which will radically reduce infrastructure costs through removal of local exchanges and much of the metro network.

The topic (“Photonic Internet Access Network of the Future”) and basic concept for the ERANET+ originate from the Mirror Group of the European Technology Platform Photonics21 which is made up of relevant governmental representatives from all Member and Associated States involved in photonics plus representatives of the European Commission (DG ICT Photonics Unit). The topic of this ERANET+ in photonics was carefully selected from a number of proposals through a democratic process among the national funding bodies involved during several Mirror Group meetings. As a consequence, the PIANO+ consortium is a subset of the Photonics21 Mirror Group. The participating countries in the PIANO+ action are UK (TSB), Germany (BMBF), Poland (NCBIR), Austria (FFG) and Israel (ISERD).

From the industrial and scientific perspective, this ERANET+ can be considered as a direct response from the public authorities in Europe to the recommendations of the Photonics21 Work Group “Information and Communication” whose more than 200 members represent the industrial leaders in this field throughout Europe. They identified “next generation broadband access networks” as high priority research topic in the short and medium term.

The decision on the topic was made in consideration of the expected impact at European level, the critical mass required, the pan-European societal and economic relevance and pre-existing European cooperation in R&D and standardisation. In addition, the following criteria were considered from the national point of view of the participating countries: the particular national interest in the field, the matching with national policies, the R&D activities and the number of stakeholders (researchers and enterprises) in the respective country and the availability of relevant national funding and/or funding programmes.

33 transnational consortia submitted project proposals under the PIANO+ call published in March 2010 of which 13 have been selected for funding, using a two-stage procedure including an international expert evaluation. From these two have been merged in one and two more haven been terminated early. Ten PIANO+ projects have been implemented successfully between March 2011 and December 2014. These projects have been financially supported with public funds amounting to about 15 M€, stemming from national programmes and from the EU-FP7-ICT work programme. In general, they aimed to increase the capacity of optical access networks; in particular, they have covered a wide area of solutions and innovations. Their achievements, among others, led to a better understanding of end user requirements, to lower service costs and to reduced power consumption. The projects’ solutions and developments include a virtual service provider, a new Indium Phosphide based laser, and several innovative approaches for signal processing and network architectures needed for the future broadband high-speed internet based on photonics.

1.2 Summary description of project context and objectives The main area addressed by this ERANET+ action, the telecommunication sector, is a key market for the European industry with the key players linked-up globally. There is a constant increasing need for higher volumes of data transfer to private homes and increasing demand for a higher speed access of the internet while remaining cost effective. These challenges require new strategies and technologies for the Access Network of the future which follow the European digital agenda goals of Pillar IV: Fast and ultra-fast Internet access: "New services such as high definition television or videoconferencing need much faster internet access than generally available in Europe. To match world leaders like South Korea and Japan, Europe needs download rates of 30 Mbps for all of its citizens and at least 50% of European households subscribing to internet connections above 100 Mbps by 2020".

The overall target of the PIANO+ call was the development of photonic technology and systems to enable widespread broadband access of at least 1Gbit/s by 2015-2020. The research was expected to be application-oriented and pre-competitive. The call asked for energy-efficient, robust, resilient, future-proof and scalable solutions.

The challenge as defined in the call is ‘The challenge is to enable economic, ubiquitous broadband access of 1 Gbit/s (and beyond) for every subscriber by 2015-20, while meeting the shorter-term needs of system operators and users. We are seeking proposals to develop photonic technology and systems for the scalable, future-proof and energy-efficient access network and its extension to the customers’ premises, including the home.’

More specifically, the following priorities were called for in the project proposals:

• seamlessly linking access, backhaul and core network architectures

• development of technologies to enable ultra-high-speed transmission

• cost-effective access and home networks based on optical fibres

• key switching and component technologies and designs to enable the above

In general, the proposals largely address the topics called for, including the following topics: home networks, radio over fibre, new components for access networks incl. power and cost-efficiency, their manufacturability and the move towards dedicated photonic circuits, addressing new access architectures, etc.

As an instrument, PIANO+ was expected to act as a strong incentive for European companies to engage in strategic research cooperation. It was meant to constitute an opportunity for them to benefit from a more efficient use of their R&D resources and from comprehensive expertise made available by a variety of research institutes.

These boundary conditions and the strategic orientation of the call finally led to the following objectives at project level:

TOUCAN “Techniques for Simplified Assembly of Optical Units for High Capacity Access Networks” was led by CIP Technologies from the UK and with the participation of Finetech from Germany. This project developed automated assembly equipment to enable the manufacture of low cost integrated photonic modules for future access networks. It developed a Dense Wavelength Division Multiplexed (DWDM) optical transceiver for use as the optical network unit (ONU) within a WDM access network. The DWDM optical transceivers exploit the full capability of a passive optical network, and in order to remain cost effective, it uses a hybrid photonic integration combined with novel automated “pick and place” assembly techniques.

The ALOHA project, “AlInGaAs Lasers for Optical Home Access” was led by CST Global, UK. This project developed the technology for AlInGaAs lasers capable of high performance and low unit cost for the home access market. The project involved a mix of materials, components and systems partners: CST (Coordinator, UK), HHI (DE), IQE (UK), plus unfunded partners Eblana (IE) and NSN (DE). The primary objective of developing a platform approach to high speed component development was achieved, and the performance of the demonstrator devices was successful to commercial grade specifications in several areas including 10Gb/s Fabry-Perot (FP), 10G discrete mode (DM), and 2.5G distributed feedback (DFB) lasers.

The project TUCAN, “Tunable CPE (Customer Premises Equipment) for Access Networks” was led by Oclaro Technology Ltd. The TUCAN project aimed to develop and demonstrate the technology for a remotely tunable universal Customer Premises Equipment (CPE) module transmitter for high bandwidth (up to 10Gb/s) Wavelength Division Multiplexed (WDM) Passive Optical access Networks. It complemented the IMPACT project which concentrated on the system aspects. The project targeted the development of a low cost tuneable transceiver technology that will be capable of meeting access network cost targets whilst maintaining high performance and reducing power requirements.

The IMPACT project, titled “Integrated multi-wavelength passive optical access system” was led by ADVA Optical Networking SE. The main objective of PIANO+ IMPACT was to develop a novel DWDM-PON (Dense Wavelength Division – Passive Optical Network) optical access system substantially reducing cost, power consumption, and footprint while improving scalability over present solutions. Focusing on the overall system architecture and the optical line termination (OLT) equipment, IMPACT targeted at developing the necessary optical and electronic technologies and demonstrating end-to-end operation.

The overall objective of the FIT project “Fiber Integrated Termination” was the development of a range of innovative optoelectronic technologies, which are crucial for the implementation of high bit rate optical networks. The main focus of FIT laid in the development of gigabit passive optical network (GPON) and all optical network (AON) configurable optical networks. Those innovative systems are mainly used in the fiber to the home (FTTH) or fiber to the basement (FTTB) areas and cater to conform to the immense broadband needs from internet applications like HDTV streaming or cloud computing.

The project ADDONAS aimed to revolutionize End User experience for all future digital network services as Video on Demand, Gaming, Storage or VPN. The ADDONAS presents a solution for creating Virtual Service Operators using the same physical infrastructure to create their own virtual connections, and offer a diverse set of various services from service providers to end users.

Moreover the ADDONAS proposes the placement of Distributed Data Centers throughout the combined Access/Metro architecture to deliver the distributed platform for mobile video, real-time applications such as cloud computing or to allow End Users to create sophisticated and virtual mini-networks for commercial, social and cultural uses.

OTONES (“Optical Access Networking Using OFDM Tones”) dealt with the field of incorporation of frequency-division multiplexing for optical access networks. The OTONES project aimed at a very efficient spectral design, allowing for low cost and reduced energy consumption. The technical objective of the OTONES project was the development and demonstration of passive optical network (PON) with a data rate of 1 Gbps+ per subscriber using a novel optical access network and signaling approach with colorless and cost efficient as well as energy efficient transceivers. The concept employs OFDM for data multiplexing and multiple accesses. The upstream (US) transmitter uses an optical carrier that is remotely supplied in the downstream (DS) by the optical line terminal (OLT) located in a central office (CO).

The SEPIANet project, titled “System Embedded Photonics in Access Networks” led by the Coordinator Xyratex, aimed to develop technology solutions for embedded optical architectures in access network head-end systems to allow significant reduction in power consumption, increased energy efficiency, system density and bandwidth scalability, which is currently unfeasible in today’s copper driven access network systems. It addressed the substantial challenges associated of developing a new optical PCB (printed circuit board) technology. The SEPIANet consortium drew on their combined expertise in a variety of technical areas to develop a complete eco-system of embedded optical interconnect technologies operating within the 1300 nm and 850 nm windows for multimode planar glass waveguide electro-optical PCBs (EOCBs).

The OCEAN project “OOFDM for Cost Effective Access Networks” aimed to develop cost-effective optical orthogonal frequency division multiplexing (OOFDM) systems for future access networks. Coordinated by Bangor University (UK), the OCEAN project brought together world-class expertise to jointly tackle the major technical objectives, mainly to develop world-first, commercially exploitable, cost-effective, versatile, >20Gb/s OOFDM transceivers with per user link parameter awareness, real-time performance monitoring, adaptive performance optimization, as well as sufficient system management features

The CRITICAL project, “Component Requirements and Integrated Transceiver Investigation for Coherent Access Links”, was led by Oclaro Technology Ltd. The CRITICAL project aimed to develop coherent transceivers and system concepts for ultra-high bandwidth access systems. Ambitious designs for the optical line terminal (OLT) and optical network unit (ONU) were addressed using functional building blocks for lasers, modulators and detectors.

1.3 Description of the main S&T results/foregrounds The TOUCAN project has lead the way to a design of a low cost WDM ONU transceiver that enables each user to get its own assigned wavelength for the downstream as well as for the upstream, thus enabling symmetrical data rates of 1Gb/s and, in later stages of the system development, data rates of 10Gb/s or even more. It developed methods for the automated assembly of the required photonic hybrid integrated circuit, components and processes for chip manufacturing:

1. Improvement to metallization process and solder for flip chip bonding;

2. Development of out of plane mirror on to waveguides for detector integration with low loss;

3. Development of manufactural reflective modulator with gain (REAM-SOA);

4. Integration of assembly structures on the waveguide wafer for alignment on InP chips.

These building blocks will be used in future products that will be taken through to volume manufacture in the UK.

The project implemented improvements to the modules for the higher accuracy flip chip bonder:

1. Improved optical assembly for recognition of low index contrast structures;

2. Improved heating plate for the bonding machine with reduced distortion on heating;

3. Novel self-levelling tool head using a ball and cup arrangement with custom coatings dry lubrication and corrosion resistance.

These elements have been built into a new machine planned for launch in 2015.

The ALOHA project addressed the need for high specification, semiconductor laser sources for Next Generation Passive Optical Networking (PON) applications, such as 10GPON, LR PON and CWDM PON. A range of device types have been demonstrated which have the potential to address the commercial specifications required. It was also demonstrated that the baseline product can be produced reproducibly in high yield, and have a roadmap for volume scale up for several of the device demonstrators. Viable commercial models were developed for foundry products at the epi-wafer, fabricated wafer, and chip level for several of the demonstrators.

The part of the project dedicated to a low cost tunable laser solution was not achieved due to the fact that the primary partner in this area (COGO) went into formal administration and was acquired in the second year of the project.

The TUCAN project developed tunable wideband DBR lasers based on the Aluminium Quaternary (AlQ) materials system, together with the technology to integrate them with a Mach-Zehnder (MZ) modulator with potential for low cost volume production. Fully integrated monolithic tunable laser-MZ PICs were realised within the project and achieved state of art performance. Laser control algorithms were developed and linked to the module control firmware. Two different prototype modules were developed as test vehicles and in order to demonstrate the capability of the overall package.

The PIC-based transceiver modules were integrated into Customer Premises Equipment (CPE) and ultimately trailed in a full system configuration, as developed within the sister PIANO+ project IMPACT. Experimental results achieved in these trials gave good confidence in the system concept and technology base needed for successful large-scale implementation.

The project culminated in a successful field trial in Austria conducted within the related PIANO+ IMPACT project.

During the IMPACT project many scientific and technical developments were achieved:

• First demonstration of a full-band tuneable DWDM multi-channel transmitter PIC for 10x

• 10 Gb/s

• First demonstration of a 5-channel modulator driver array driving the PIC’s MZM with 10 Gb/s line rate

• First demonstration of DWDM multi-channel receiver based on a novel packaging concept leveraging flip-chip technologies for photo-diode and transimpedance amplifier integration

• First demonstration of a centralized wavelength controller for automatic tuning of the attached ONUs on start-up and high precision closed-loop control

• Demonstration of enhanced network function virtualization (NFV) capabilities employing a commercial off-the-shelf (COTS) server collocated with a programmable OLT aggregation node in the central office (CO)

• First demonstration of novel DSP methods (especially sub-carrier multiplexing with Nyquist pulse shaping) for DWDM-PON capacity scaling

• First demonstration of novel SFP+ based DWDM-PON with 10 GbE line rate in a lab trial and tuneable SFP+ based DWDM-PON with 1 GbE line rate in a field trial

The scientific and technical achievements resulting from the FIT project included the design concept for the optical gateway, involving all the necessary interfaces for the end-user. The design concept was based on an analysis of the possible application scenarios. The two typical configurations cover practically 90% of the possible applications. The “Fiber to the Home” (FTTH) configuration has the advantage that in-house IP services can be coupled at the MDU level, simplifying, thus, the overall cabling effort. The second configuration is “Fiber to the Building” which is appropriate for apartment buildings with 6 to 24 units.

Another major development within the FIT-project was related to an innovative GPON-chip with multiple interfaces. The systematic system characterization showed overall fabrication cost reduction, data bandwidth increase and decrease of the overall power consumption. In order to enable the integration of the innovative GPON-chip in an optical gateway, reference systems (“evaluation boards”) were developed. After developing the first system, which was delivered for further integration in the optical gateway, the research activities concentrated in the miniaturization of such a system towards an SFP form factor. First system results showed that such a form factor is feasible and can fulfill the overall system requirements.

An additional innovative design was developed within the project, provides an optical interface (plug) fully compatible with the RJ45 standard in terms of geometrical dimensions, as well as necessary electrical interfaces.

A system test setup was organized within the FIT-project, with the aim to analyze the installation scenario with multiple services with different in-house access points. However, due to the delay of


9

the UGW integration, the project components could not be characterized and, thus, the validation of the aimed specifications could not be achieved.

With the aim to develop a fast and accurate identification of a fiber defect, the research focused on methods to be deployed from the ONU side. First module versions were realized, on which the microcontroller was operated through an evaluation board. The corresponding results demonstrated that the complete fiber length range could be covered.

In the ADDONAS project, the main achievements include architecture solutions in two areas - at the infrastructure level as well as on the software control level thus providing complete solution for access/metro networks. The new architecture for the metro and access networks have been proposed. It uses main roles such as Infrastructure Provider, Virtual Service Operator and Service Provider to allow unrestricted access to services.

The following improvements were done to demonstrate the ADDONAS architecture:

1. Symmetrical access with high bandwidth for all customers

2. Non-blocking architecture to distribute the traffic within the FTTH node

3. High speed trunk interfaces for non-blocking traffic forwarding

4. Support for higher layer protocols

5. Support for real time configuration changes occasioned by the control plane (end user request new service)

6. Architecture change to show BRAS features on the access node.

7. Dynamic VLAN and Multicast support

8. IPoE supporting DHCP server

9. Open flow configuration option for SDN network

During the OTONES the following developments were achieved in the Multiplexing with OFDM technology:

• Dynamic data rate allocation among users was targeted at by changing the amount of OFDM subcarriers attributed to each user, allowing for a fine granularity.

• Demonstration of a symmetrical DS/US data rate of 9.6 Gbit/s in a 12.5 GHz wide optical channel. The optical C-band provides an optical bandwidth of 40 nm, corresponding to potentially 400 of these channels, resulting in a total capacity of 3.84 Tbit/s to be delivered by a CO to a single feeder fiber. Eight data streams of 1.2 Gbit/s in one 12.5 GHz channel. With 400 channels of this type, this amounts to 3200 users each supplied with a data rate of 1.2 Gbit/s.

• On the component level, a design was developed for a transmitter with IQ modulator and with integrated receiver photodiodes using the silicon photonics platform. Moreover, a high-density photonic integration by co-packaging an SOA chip and the transceiver chip was targeted. The consortium introduced a novel scheme for a photonic interconnection of the two chips, reducing packaging cost and improving coupling.

• For the system demonstration a fiber laser was used with ultra-low linewidth for transmitting 16QAM. For using less advanced and more cost-efficient lasers, phase noise poses a problem, and mitigation techniques need to be employed. With the use of integrated devices


10

for frequency comb generation, the energy consumption could be reduced as well as the overall investment cost, especially when upgrading from a few optical channels to the maximum number.

• The use of a PON architecture with power and wavelength splitting combined offers low cost of ownership. To increase the network reach, a remote hub with optical amplification was used. The requirement of remote powering is a small price compared to the advantage of a larger coverage.

• Compatibility with legacy networks is ensured with their multi-wavelength structure. The WDM overlay enables also CO consolidation: A number of previously distributed CO or OLT can be concentrated in one location. The consolidated CO is connected to a metro ring network on one side and via a single feeder fiber to the access network on the other side.

The SEPIANet project consortium has tackled the substantial challenges associated with bringing to fruition a disruptive new optical PCB technology and supporting eco-system. These efforts culminated in the successful demonstration of 3 fully integrated planar glass waveguide optical backplane and pluggable connector platforms driven by system embedded and external 850 nm and 1310 nm optical transceiver technologies and validated for both in-system and system-to-system optical connectivity.

The OCEAN project concentrated in the making of commercially-available, low-cost optical/electrical components. The project developed a number of world-first, real-time, end-to-end, adaptive OOFDM transceivers operating at signal bit rates of up to 30Gb/s for various cost-sensitive application scenarios. The transceivers offered unique features including, for example, on-line performance monitoring and optimization, digital signal processing (DSP)- based effective compensation of both linear and nonlinear component/system/network impairments, as well as excellent performance flexibility and adaptability to both channel spectral characteristics and data traffic conditions. In addition, the feasibility of utilising conventional 10G-class intensity modulators to achieve >100Gb/s/λ OOFDM transmissions has also been experimentally confirmed for short-reach applications. The OCEAN results indicated that the development of cost-effective, high-speed, flexible and intelligent OOFDM transceivers is practically feasible for the realisation of software-defined networking-enabled elastic optical networks satisfying highly dynamic end-users’ data traffic patterns.

During the CRITICAL project, new Indium Phosphide based lasers were designed by Oclaro using the AlQ material system to enhance behavior and performance at higher temperature. The laser cavity and gratings were redesigned to improve laser linewidth according to the system requirements of other commercially deployed coherent optical communications systems.

Key elements of the real time ONU demonstrator successfully implemented, in particular equalisation and carrier recovery with 3 Gb/s throughput. A resolution of 5 bits in the analogue-to-digital converter (ADC) has been demonstrated to be sufficient for the differential carrier phase recovery implemented on the field-programmable gate array (FPGA).

1.4 Potential impact

In the past, international cooperation in the exploitation of the global broadband and mobile telecommunication market turned out to be beneficial and fruitful and often superior to individual (e. g. purely national) approaches or small scale cooperation. As expected, similar impacts have been induced through this European level cooperation as it came to development of fibre based access networks.

This joint European approach towards fibre access technology aimed at helping to bundle the know-how and the resources of the relevant European institutes and companies, to generate synergies and to facilitate a common technology platform. This included complementary expertise in the different companies and institutes providing high-tech solutions for photonics in Europe, but also competitors, which used PIANO+ as a platform for the establishment of a joint strategy and in order to prepare common standards.

Altogether, PIANO+ contributed to a higher degree of coherence and coordination at European level while the participation of the relevant national funding bodies and the European Commission led to reduced duplication and fragmentation.

The many developments made in the course of the projects have and will have in the future an impact on the industry, academia and society as a consequence. Several of these developments have a commercial prospect. In some projects, not all objectives were met, and yet, they have laid firm basics for solutions still to be developed outside the projects' time frame. Some technical breakthroughs as well as the understanding achieved within the projects will continue to serve the photonics industry.

In terms of utilization and exploitation, the projects were able to present impressive results in most cases including commercial solutions and components. In some cases, further unexpected achievements were accomplished within the time scale of the project. Apart from approaches for direct commercialization in the short or mid-term, some results will require further development before they can be commercialized – single successor projects following-up the PIANO+ outcomes have already been launched, respectively submitted. So far, at least one patent has been filed (resulting from ALOHA) and a WDM-PON trial has been launched in Austria as an outcome of the related projects IMPACT and TUCAN. Other participants plan for the licensing the technology developed in the project (e. g. SEPIANet). Some of the results of the more advanced projects were published in journals and presented on the occasion of various trade fairs and conferences. Moreover, the results will help improving the teaching contents and advancing education at graduate and post-graduate level and through the academic partners in many of the projects.

Last but not least, several participants have plans for the continuation of the collaboration with their consortium partners based on the project experiences and achievements.

1.5 Analysis of the outcomes of the call

Being the first ERA-Net-Plus project in the ICT domain ever, PIANO+ required considerable pioneering work. Neither was the target group familiar with the format of the EN+ funding scheme, nor were the participating funding bodies experienced with the implementation and occasionally had to develop solutions along the way.

In consideration of these prerequisites it can be stated that the PIANO+ call published in March 2010 led to a good overall response in terms of number and range of proposals. 33 transnational consortia submitted project proposals under the PIANO+ call of which 13 have been selected for funding, using a two-stage procedure including an international expert evaluation. From these two have been merged in one and two more haven been terminated early. As a result, ten PIANO+ projects have been implemented successfully between March 2011 and December 2014.

The accomplished projects were of largely good or very good scientific technological quality and the success rate was high. Only one, maybe two of the projects stayed behind expectations, respectively failed in achieving central goals (see section 1.3). Some impressive breakthroughs have been achieved within the projects and a considerable number of projects resulted in (subsequent) developments with a commercial prospect. Their achievements, among others, led to a better understanding of end user requirements, to lower service costs and to reduced power consumption.

However, the utilization of the available public funds (regional, national and EC) stayed behind expectations: while projects requesting about 83 % of the available funds were selected, finally only 60 % of the available public funds were consumed/claimed by the R&D projects. (The presumed reasons for these facts are discussed in section 1.6.)

Having induced projects with a consortium size between 3 and 10 partners (in average 6 partners) coming from two to four different countries, the PIANO+ call demonstrates good complementarity to national/regional and European projects. The former normally do not allow for trans-border cooperation while the European Framework Programme calls mostly address larger projects (or pure SME projects, alternatively) and require considerable efforts in the application phase at a low success rate. Apart from that the PIANO+ call addresses a clearly defined topic in a vibrant sector. Its scope is narrower than the areas of the FP//H2020 Work Programmes (e. g. ‘Future Internet’) while it is wider than the scope of a single FP7/H2020 call topic. Again this can be seen as a complement to other funding schemes. Moreover, the decision on the topic was not only made in consideration of the expected impact at European level, the critical mass required and the pan-European societal and economic relevance but also in view of the particular national strengths in the field and of the R&D activities and the number of stakeholders (researchers and enterprises) in the participating countries. Thus, the PIANO+ projects hardly could have been realized under any other existing funding scheme.

A significant reaching out to new constituency was not observed. A vast majority of the participants have already been involved either in national/regional or in European projects or in both. Also, some of the projects were based upon or derived from previous European or national projects.

On the other hand, the leverage effect on networking was fairly strong, as several new connections, cooperations and partnerships have been established which can be expected to last beyond the


13

duration of the projects. Several participants reported that, based on the project experiences and achievements, they have concrete plans for the continuation of the collaboration with their consortium partners in terms of general partnership, through subsequent activities building upon the project achievements or by way of new collaborative research projects.

Moreover, PIANO+ proved its ability to act as stepping stone for SMEs to collaborate at European Ievel. Its focus on collaborative research projects which involved academia/science and industry, a transparent project size, a comparably good success rate and moderate formal application requirements (compared to other funding schemes including EU FPs) led to a relatively high participation of SMEs of about 40 %. In addition, access of SMEs to European collaboration was facilitated in a threefold way:

• through the active support from the participating national funding bodies;

• through research organisations being experienced in European projects who were acting as ‘scouts’ for European funding opportunities and who largely initiated and organised the collaborative R&D projects,

• and through medium enterprises with consolidated partnerships at EU level who helped integrating small and micro companies in the consortia.

Consequently, the added value perceived by the partners of the transnational projects mainly referred to the issues outlined above:

• Favorable format of call and funded projects;

• Beneficial complementarity to other funding schemes;

• Good accessibility for SMEs;

• Acceptable efforts for application process and formal requirements.

The largely positive perception of the PIANO+ call can be illustrated by the fact that a strong interest on part of the consortia was revealed on the occasion of the mid-term event held on 29 April 2013, including requests for a similar subsequent call.


14

1.6 Critical (self-)assessment of the call implementation

At the time when PIANO+ was contrived and started very few experiences were available with this specific instrument (ERA-Net-Plus scheme). In particular, neither the participating funding bodies nor their EC counterparts were adept at implementing such an EN+ project. Consequently, several problems and obstacles were faced during implementation, several solutions had to be found in the course of the project and some lessons have been learned which then have been applied to the subsequent EN+ like OLAEplus and BP+, whenever feasible.

During the phase of call preparation and publication no specific problems occurred. However, it was realized that the complexity of the different applicable national funding rules combined with the joint transnational eligibility criteria had a negative effect on transparency and thus to a certain extent impeded consortium building. In order to bring together potential proposers, a central call launch event has been organized in Berlin, offering comprehensive information on the call, participation rules and procedure. However, reach and attendance was moderate and the format did not work well for the purpose of facilitating partner search and consortium building. In that sense it did not meet expectations. Similar experiences have been made with an analogous OLAEplus event so that for BP+ this central event was replaced through a number of smaller events. In all three cases well-frequented partner search facilities (online databases) were offered on the call websites.

Likewise, the evaluation and selection phase ran smoothly without any significant problems, apart from the fact that the demands for the available national budgets were heavily unbalanced. This did not affect the selection process itself but led to an underutilisation of the available funds by more than 15 % already at the selection stage (see also the allocation of funds and use of budgets section below).

Unexpectedly enough, it was the contract negotiations and launch of R&D projects phase that led to significant delays which persisted and propagated throughout the entire duration of PIANO+. Firstly, several changes within the consortia occurred – for various reasons. Partners withdraw in the short-term, replacements were sought, and formal requests for changes of different kinds were presented and processed by the funding bodies – all-in-all a time-consuming process. Secondly, the entire process of contract negotiation and preparation itself (including submission of national CPFs, provision of up-to-date information related to financial viability, provision of authorised signatures, conclusion of consortium agreements, etc.) took considerably longer than expected.

Finally, most of the projects were started in the course of the year 2011. Two of the selected projects (IMPACT and HIAT) were merged into one (IMPACT) due to the withdrawal of three of the partners. The merger was favoured and enabled by the fact that both projects shared some communalities – technically and in terms of participants. Two other projects (FBOSA and OBTAIN) did not take-off duly and were cancelled in 2012.

Another problem arising from delays were the diverging starting dates of the contracts of the different participants within one project consortium. The issue was worsened by the different formal procedures in the participating countries which could not always be synchronised well, partly also due to inadequate communication on the part of the funding bodies. By the way, later in the project this led to applications for cost-neutral extensions of the project duration from participants in four of the projects.


15

The delays and withdrawals described above had a significant effect on the allocation of funds and the use of budgets. While there was a good overall response to the call in terms of budget requested, the demands for the available national budgets were heavily imbalanced. As a consequence less than 85 % of the available public funds could be allocated to the selected projects (19 m€ instead of 22.3 m€ being available). This was mainly due to the fact the UK was oversubscribed and the entire balancing pot had already been allocated for the purpose of funding UK participants exceeding the available national budget (incl. EC top-up). Once the selection list was agreed, the high discontinuation rate, the significant number of withdrawals and several subsequent changes of the project configurations led to a further reduction of the allocated budget by more than three million Euros (comparing the selection list figures with the figures in the funding contracts/acts finally issued). On a small scale this can be seen as a normal effect as contract negotiations often lead to a minor reduction of the requested amounts. However, the degree of reduction in PIANO+ is due to additional reasons, especially on the part of Israeli participants where the decrease is particularly high:

• ECI – the biggest Israeli company initially involved in the project proposals - has changed its strategy after it was acquired by external investors and therefore has dropped out of two projects. They were replaced by Finisair - but with significantly reduced budget.

• Two projects were merged during the negotiation phase, resulting in an overall reduced budget

• Two projects were terminated, one in the negotiation phase and one after one year duration.

• The late failure of negotiations (with single participants or with entire projects) prevented the utilization of the reserve list. Apart from that a project dropping out often cannot simply be replaced by the next project on the reserve list as size (in terms of budgets and requested funding) and composition (in terms of countries involved) may be completely different.

Finally, during the implementation of the R&D projects a further reduction of the actual public funding occurred due to a certain degree of underspending on the part of the projects (which is normal) and/or due to disallowance of a part of the claimed cost by the funding bodies – which also is a normal procedure in many countries. In the end only about 60 % of the initially available public funds were spent. While, due to its structure, a ERA-Net(-Plus) project will never be able to spend 100 % of the available funds, the overall utilisation of funds in PIANO+ was clearly below average.

Lessons learned from the experiences regarding the negotiation, the modification and the launch of the R&D projects, including the best possible utilisation and allocation of funds, are as follows:

• Realistic financial commitments from the participating countries and an overall good balance of the available budgets are crucial. Severe mismatches at this early stage cannot be balanced later - not even by using a generous balancing pot. The only chance consists in an increase of the oversubscribed national budget(s) – which very rarely happens.

• Thorough and transparent information as well as active support towards the proposers is highly important in order to make them fully understand the requirements and implications of the application process and of the subsequent funding.

• The funding bodies might think about asking for explicit confirmations from the proposers during the submission process (‘I confirm that I have read and understood …’) to avoid invalid consortium setups and non-compliance with the funding rules.


16

• The funding bodies might also think about asking for letters of intent from each single participant to reduce the rate of withdrawals, in particular late in the process.

• Once the selection list has been agreed, a mandatory deadline for the submission of complete (national) CPFs, including any compulsory information, should be fixed. Project consortia not complying with these requirements should be excluded from the competition and projects from the reserve list should be taken into account as soon as possible.

• In general, the reserve list can only be utilised if it is possible to skip projects on the selection list. As we understand this option is largely impeded by a prohibitory rule in H2020, Such a rule should be abolished for the sake of more flexibility and better utilisation of the available public funds.

Admittedly, the transnational monitoring of the running R&D projects was not performed as originally planned. The PIANO+ monitoring concept was set up early and on schedule but the implementation got stuck in the middle and it did never get up and running unless towards the end of PIANO+ as the final reporting is concerned. Consequently, the monitoring of the R&D projects and the periodic reporting took place on national level only and were supervised by the respective national funding authorities from the beneficiaries’ countries. The reasons remain rather fuzzy: As the national monitoring follows attuned routines it worked well and was largely perceived as sufficient by the funding bodies. Also, due to the dragging negotiations, there was a high degree of desynchronisation (e. g. projects were launched successively over a longer period) and the overall schedule was delayed. Moreover, there may have been an influence by a latent lack of resources on the part of the funding bodies (see general observations below).

According to national law, national monitoring is mandatory for projects funded under national grant agreements (as is the case with PIANO+) so that it presently cannot be replaced by transnational monitoring. Consequently, transnational monitoring will require beneficiaries to perform additional reporting duties. In order not to overload beneficiaries with administrative duties those should be selected wisely and economically. National and transnational reporting should complement each other, avoiding any duplication of work.

As eligible costs in PIANO+ (mainly) consisted in the funds paid to the beneficiaries of the R&D projects, the financial monitoring at PIANO+ level essentially depended on the financial monitoring of the R&D projects. Apart from the fact that there was a persisting delay and de-synchronisation from the starting phase, the figures were steadily received with a significant delay for a number of reasons:

• Most of the (national) cost claims from the R&D projects were due subsequently at the end of the reporting period (e. g. the calendar year) - plus f. i. three months allowed for the submission - which results in a delay of about 15 months after the start of the reporting period.

• In some cases the submission of the cost claim was additionally delayed by fault of R&D beneficiaries not meeting the deadlines.


17

• In some cases the cost claims did not yet cover all the costs incurred in the period but those costs were only claimed in a subsequent period – comparable to the adjustments of Forms C in FP7 projects.

• Occasionally additional delays occurred on the part of the funding agencies in compiling and forwarding these figures to the coordinator.

As consequence, throughout most part of PIANO+ no comprehensive and up-to-date figures were available. They were only received increasingly towards the end of the project.

General observations:

In summary it can be said that the implementation of this pioneering project was all in all successful and that it was characterised by a good and increasingly trustful cooperation between the partners. However, the overall workload was much higher than initially expected, not only as the implementation of the joint call is concerned but also due to the high absorption of resources by formal requirements related to the EC top-up, respectively the EC grant agreement.

As beneficiaries of the EC, the national funding bodies found themselves in an unusual role and confronted with several “over-and-above” tasks exceeding their normal duties. As a result, a latent lack of resources on the part of the funding bodies became apparent which occasionally hampered and delayed the implementation.

The lesson for future actions to be derived from this is twofold:

1. Funding bodies should be aware of the actual workload related to an ERA-Net-Plus/Cofund action and provide sufficient resources from the very beginning;

2. The EC should do its best to simplify the instrument(s) and to waive any dispensable formal demands.
