Energy Procurement Framework
r66 G66 b67
r66 G66 b67 • Reduce primary demand for
both heat and power
• Select plant to match this reduced demand
• CHP philosophy based on lowest possible heat
requirement and highest possible electrical generation efficiency • Multiple energy sources –
incineration heat, biomass heat, dual fuel (gas/oil) boilers and CHP
Design Philosophy - demand vs generation
Utilyx New proposal

•Tender Stage - Internal design & commercial modelling
•½ hourly technical model developed allows us to test
different technologies against actual load profiles & run
sensitivities
•Due Diligence review of technical and commercial
proposition during contractual negotiations
•Planning Application during contractual negotiations
•Detailed design to Stage D/E
•Final co-ordination & detailed design development

Clinical Waste Incinerator
• 350kg/hr clinical waste
• 2725 tonnes pa
• 1600kW Steam production providing 11,600MWh or 18% of the total heat load
• Savings: Offset Gas boiler consumption & waste disposal costs
• Disposal of all Addenbrookes hazardous clinical waste
•
• Supports the destruction of clinical waste from other local business
Solution Technology - Incinerator
Core of the scheme is the Rolls Royce Bergen CHP unit
• 7.5 MW electrical capacity
• 4.0 – 5.0 MW thermal capacity
• Production of steam and hot water
• Savings: Offset elec consumption & Offset boiler gas consumption, CO2 reduction
The gas fired CHP engine will provide 50,000MWh of power and 28,500MWh of used heat pa, equating to 78% of the remaining power demand and 44% of the heating demand
Solution Technology - CHP
Renewables provided by Waste wood fire Biomass
• 2 x 3MW thermal capacity
• WID compliant
• 30% or 18,800MWh pa of the heat provided by renewable waste wood fired biomass boilers with expansion capacity to increase annual output by over 200%
• Savings: Offset boiler gas consumption, reduce CO2 & RHI income
Solution Technology - Biomass
• Resilience against future gas price inflation and protects the impact of gas price inflation with respect to the CHP.
Solution – balance of plant & basic overview
• Gas & Oil fired boilers
• Fired section of HRSG
• Steam to LTHW system

Overview of Savings
• NPV £36M over 25 year term
• Cash positive Y1
• 30,000t CO2 Savings pa
• 27% above NHS CO2 reduction target
• 25 (+5) year contract with CUH hospitals
• Guaranteed Savings through conversion efficiency, generation, demand side reduction
and government incentives (RHI).
• Project is under the Carbon & Energy Fund framework agreement
• The scheme in total is funded over 25 years via a combination of Aviva & Green
Investment Bank (GIB) funding
• £36 million capital investment . Includes energy centre, underground tunnel link and
demand side measures
• MITIE / Utilyx will operate the plant for 25 years and guarantee the plant performance.
Funding & Commercial Structure
• Proposed scheme is compared against and agreed Base Year load & consumption profile
• The savings are calculated initially using base year tariffs and include
Day & Night Electricity tariffs, Export elec Tariffs, Gas Tariffs
Gas & Elec CCL, CRC £/tonne CO2
• Guaranteed Savings are indexed at 2.5% or RPI
• The Trust pay the funder an MSP (Minimum Service Payment) on a quarterly basis.
• The Trust Pay Utylix the FM fee quarterly adjusted annually for performance
• Excess savings generated through improved performance against the proforma are
shared, providing incentives for continued improvement
• Minimum take agreements
• Load profile mechanism
Payment Mechanism & Guaranteed Savings
• We undertook a number of public consultations and Pre App submissions to both the
County and City Council to ensure we had full stakeholder input to minimise potential
obstacles.
• One of the issues raised was the use of Biomass in the scheme and its potential for
discharge issues raised by the adjacent users. The discharge modelling undertaken and
EIA aided this process, which again will be regulated by the permitting authority.
• We are finalising a local fuel contract which gives surety of supply and in essence was a
good news story for the County, who in turn have a long term contract with the waste
supplier , whereby the waste wood goes to landfill, our scheme eliminates that need
• We are through the detail design process making minor changes to the aesthetics of the
building through technical necessity, which will form a subsequent Section 73
application, due for submission shortly.
Planning – the challenges
Current Project Programme:
• The Archaeological dig - 25th November to February 2014, concludes 4no planning
conditions ( 3no of relating to Archaeology and 1no Geotechnical.)
• Certificate of Commencement (CoC) is planned for the mid April 2014,
• Commencement on site early May 2014.
• 24 month development programme, including final 6 months dedicated for
commissioning, setting to work and optimisation
• At Practical Completion the commencement of 25 year term & savings / performance
obligations will apply.
