Siemens AG
Executive Summary
In this report, Siemens has analyzed the status and future trends of global gas
to power generation and its implication for China. Siemens believes these trends
are conducive to the development of the Chinese energy sector. Specific
recommendations are suggested for China with regard to policy making.
Global Oil & Gas markets enter an era of ―New Normal‖ with the emergence
of competent, flexible US shale gas producers. Natural gas is the fastest-growing
fossil fuel with 1.9% CAGR1until 2040 according to the International Energy

Outlook 2016 by EIA1. Coal is the world's slowest-growing energy source, rising
by 0.6% per year through 2040.
Abundant clean burning (relatively to many alternative fuels) natural gas
resources and robust production - including rising supplies of tight and previously
deemed stranded gas, shale gas, and coal-bed methane - contribute to the strong
competitive position of natural gas. According to IHS2, the global supply of natural
gas surpasses demand in the near future,e.g. in 2020 natural gas supply will be
3,827 BCM3while demand will be just 3,810 BCM.
Overall, the strong growth of natural gas production between 2015 and 2040
can effectively meet rising demand without major upward price disruptions.
Global LNG4is being commoditized and reshaping the global natural gas market.
The attractive pricing of Natural Gas makes it a good choice for new fossil
generating. By 2040 coal, natural gas, and renewable energy sources will provide
roughly equal shares (28%-29%) of world electricity generation - a significant
change from 2012, when coal provided 40% of all power generation.

The recently announced China 13th FYP1sets ambitious goals for gas fired
power generation with 50GW2of added generation over the 2016-2020 periods.
Meanwhile gas consumption in TPEC3is expected to grow from 5.9% to 8.3%10%
by 2020, aiming to address the challenges in emissions, coal reduction, and
renewable development faced by the China energy revolution.
Despite the low global gas prices, it is still difficult to keep gas fired
electricity prices low due to the lack of competitive access to the midstream
infrastructure required to import cheap oversea LNG. The LCOE4for CCPP
6 is
~0.8 RMB/kWh, approximately 2.5 times of coal. Around 75% of the LCOE
comes from the cost of Natural Gas.
Therefore, in order to fulfill the ambitious target of the 13th
FYP it is
necessary to leverage the best practices from other countries and to employ a
holistic approach to the integration of the Gas to Power Value Chain (hereafter
referred to as G2P Value Chain).
Countries like Morocco, Mexico and Brazil are already committed to develop
low emission gas fired power generation by optimizing and integrating the total

G2P Value Chain via institutional reform, innovation in business models, and
adopting advanced technologies etc.
One of the main opportunities in maximizing the most efficient use of natural
gas is to evaluate a ―business model integration‖, which connects the
up/midstream gas project development (e.g. Liquefaction plant) with the
downstream power generation project, and employing ―technology/System
Integration‖ in the liquefaction/regas/power generation process, which provides a
lower cost over the whole G2P Value Chain.
Siemens offers a comprehensive portfolio of products and solutions integrated
in upstream exploration and production, midstream liquefaction and pipeline
transmission, downstream power generation, transmission and distribution along
the G2P Value Chain
For LNG, Siemens has been offering advanced technologies, modular designs
with a proven track record in ranges of liquefaction technologies including Micro
LNG (up to 0.003 MTPA1), Medium LNG (0.1-2.0 MTPA), Floating LNG, and

covering over 3,000 gas turbines and 2,700 Gas Engines for power generation,
representing in excess of 260GW of large size Combined Cycle Power (CCPP) of
installed capacity.
The Siemens 8000H recently commissioned at Lausward Fortuna CCPP in
Düsseldorf (Germany), on January 22, 2016 set three new world records:
maximum electrical net output of 603.8 MW in a single-shaft configuration; ~61.5%
for net power-generating efficiency; and an overall CO21reduction in the amount
of 2.5 MTPA.
In January 2017, Siemens received the first 8000H Gas Turbine order in
China - the combined cycle unit in its Black Point Power Station in Hong Kong.
There are now a total of around 80 sets of SGT-8000H sold worldwide. The
customer is Castle Peak Power Co. Ltd. (CAPCO), a joint venture of China
Southern Power Grid International Limited and CLP Power Hong Kong Limited
(CLP Power). Scheduled to be in operation before 2020, the plant will have an
installed total capacity of more than 560 MW – enough energy to supply
approximately a million households with electricity.
Since 2003, Siemens has been successfully co-operating in technology of
large sized gas turbine (E, F and H-class) with its Chinese strategic partners, and

has supplied closed to 60 sets of E and F-class gas turbine for China with
manufacturing in Joint Ventures, and for export projects as well.
Starting from 2007, Siemens has also been successfully cooperating with
Zhuzhou Nanfang Gas Turbine Packaging and Installation Co. Ltd. (ZNGT, a
subsidiary of AVIC) on the localization of small gas turbines, and in 2015 with
Hangzhou Steam turbine Co., Ltd. (HTC) to kick off localizing medium size gas
turbines. Both gas turbines are applicable to distributed power generation. Siemens
is very much willing to share its experience achieved worldwide with Chinese
peers (e.g. Institutes, Universities) and the Chinese government.
In digitalization, Siemens provides unique value proposition for its customers
by providing domain know-how and expertise in combining Operating Technology
and Information Technology. In the Yuanba project for SINOPEC1, which is
dedicated to continuous pipeline monitoring in order to ensure safety and detect
leaks, Siemens provides redundant failure resilient Industrial Ethernet solution
with fiber-optical cables, a virtual private network (VPN), and industrial network
components capable of withstanding hazardous environmental and locational
conditions. The solution helped SINOPEC reduce leakages by continuous
surveillance, achieve higher uptime by continuous data availability, and reduce

Digital Power Plant (DPP) solution into China in a pilot project together with
SPIC. DPP provides with professional management of plant’s asset and is designed
to optimize rotating equipment economy and availability with continuous
surveillance and equipment status assessments etc.
Siemens would like to recommend the following aspects to be specially noted
for the Chinese government:
1) Encourage projects aimed at building up integrated G2P Value Chain
utilizing upstream, midstream, and downstream resources at home and abroad,
private and state-owned or mixed ownership from both a business model
perspective and/or a technology perspective
2) Improve Third Party Access to midstream SOE(State Owned Enterprise)
facilities, and ease approval of LNG Regasification Terminal construction for
Non-NOCs, thus to make full utilization of low cost LNG in global market
3) Define measures and take timely actions to encourage current gas power
enterprises to make full use of the advantages of gas power
4) Strengthen the economics of gas power generation via a feasible market
mechanism. e.g. to deregulate pricing in gas and electricity to enable effective

business model construction, and speed up the electricity dispatching reform to
shorten the time to build up the market mechanism for Natural Gas
5) Accelerate the reform of electricity dispatching etc. that encourages gas
fired peaker and CHP applications
6) Adopt the most advanced technology on the whole Gas to Power Value
Chain.
7) Further controlled opening of the Chinese market may encourage
international companies with advanced technologies in planning, system design,
engineering, key equipment manufacturing (e.g. Gas Turbine), service and
R&D1to further enter into China, and cooperate with Chinese companies in
various ways.
Siemens believes these recommendations will bring more benefit and energy
to the long term successful development of the Gas to Power Value Chain in China.
1.Global Trend of Natural Gas Market
Abundance of Natural Gas Supply in Oil & Gas “New Normal”
Global Oil & Gas market enters an era of ―New Normal‖ with the emerging
of competent, flexible shale gas producers in US since the big price collapse of
crude in the last two years. Natural gas, as one of the most attractive fossil fuels
1 R&D Research and Development
Integration of the natural gas value chain into power generation
-
Siemens AG All Rights Reserved©
being a high heating value fuel that is clean, environment protective, rich in
reserves, and economically viable, has become the fastest-growing fossil fuel in
the world energy consumption outlook.
According to International Energy Outlook 2016 by EIA, global natural gas
consumption grows by 1.9% per year until 2040. On the other hand, coal is the
world's slowest-growing energy source, rising by 0.6% per year through 2040. By
2030, natural gas surpasses coal to become the world's second-largest energy
source after liquid fuels.
Abundant natural gas resources and robust production—including rising
supplies of tight gas, shale gas, and coal-bed methane—contribute to the strong
competitive position of natural gas. According to IHS, global gas demand reached
3,430 BCM in 2015, and will reach 3,810 BCM in 2020. In the meantime, global
gas supply is estimated to reach 3,827 BCM in 2020.
Among the Natural Gas supply, LNG grows quickly. Global LNG capacity
Integration of the natural gas value chain into power generation
Siemens AG All Rights Reserved©
will grow at an average annual rate of 4.6%, reaching more than 440 MT1by 2025,
therein North American LNG exports will rise rapidly, from 0.3 MT in 2015 to 75
MT in 2025.
Attractive Natural Gas Price for Downstream applications
With the high reserves of gas supply, gas price diverges from crude for the
first time. According to IHS, the nominal price of Dated Brent rose from
US$52/bbl in 2015 to US$80/bbl in 2020, to $122/bbl in 2030, and to $151/bbl by
2040, whilst Henry Hub price for Natural Gas is forecasted to remain relatively
flat with a slight upward trend, however still within the range of US$3-4 per
mmbtu during the same period. Thus Asian prices for Natural Gas moved
gradually away from oil-indexation and in the long-term became set by a hybrid
mix of oil-indexation and Henry Hub prices.
Emerging Global Natural Gas Market
Overall, the strong growth of natural gas production (and associated reserves)
between 2015 and 2040 can effectively meet the rising demand without major
upward price disruptions. Global LNG is being commoditized and the global
natural gas market is taking the shape. Market players are determined to boost
downstream applications especially in power generation and transportation, and

make it a good fit during the global march towards renewable energy both from a
transitional and a compensational point of view.
Natural Gas for Power Generation for Lower CO2 Emission
With attractive pricing of Natural Gas, it becomes a more and more lucrative
choice for new fossil generating plants given its relatively high fuel efficiency, low
emission profile, and the moderate capital cost of gas-fired plants. Additionally, as
more governments begin implementing national or regional plans to reduce carbon
dioxide (CO2) emissions, natural gas is displacing consumption of the more
carbon - intensive coal and liquid fuels with around 55% CO2 emission per kWh
of coal and 70% of oil.
Along the course to more renewables, by 2040 coal, natural gas, and
renewable energy sources will provide roughly equal shares (28%-29%) of world
electricity generation—a significant change from 2012, when coal provided 40%
of all power generation.
2.Major Challenges in China Gas fired Power Generation
Integration of the natural gas value chain into power generation
Siemens AG All Rights Reserved©
New Approach Required to Address Challenges in the Energy Revolution of
China
China is undergoing an energy revolution driven by efficiency, selfsufficiency,
and innovation in energy supply and demand to tackle the main challenges of
emissions, coal reductions and balance grid operation with renewable energy
development.
China’s power sector is the single largest air emission source in the world due
to the massive use of coal as fuel – generating 4 billion metric tons of CO2 vs. 2 in
US, 1 in Europe and generating 9 MMT1SO2
2while 11 MMT Nox
3.
Although over investment in coal fired power is now strictly controlled by the
government, coal consumption for power will keep increasing slightly until 2030
(12.7 Billion tce4in 2014 to 14.3 billion tce in 2030). On the other hand, rapid
development of renewable generation, especially Wind and Solar (26.2% CAGR
from 2010 to 2020), which have intermittent energy supply attribute, gives high
pressure to grid stability and demands more capacity for peak-follow. Additionally,
1 MMT – Million Metric Tons 2 SO2 - Sulfur Dioxide 3 Nox - Nitrogen Oxides 4 Tce - Ton of Standard Coal Equivalent
Integration of the natural gas value chain into power generation
Siemens AG All Rights Reserved©
with the goal of decreasing at least 60% of CO2 emissions per unit of GDP1from
2005 levels by 2030, all in all would command an expanded use of natural gas as a
source of primary energy.
In the 13th FYP at the end of 2016, China planed ambitious gas supply goals
to make 12% CAGR until 2020 i.e. 360 Bcm in 2020, Gas consumption in TPEC
to grow from 5.9% to 8.3%-10% in 2020, meanwhile China also plans 50GW new
add of gas power during 2016-2020 (30 GW CCPP + 5GW SCPP2+15GW DG
3).
In the 2017 edition of World’s Energy Outlook, BP4estimates that China will be
consuming approximately 570 Bcm of natural gas in 2035 from almost 200 Bcm
in 2015.
Considering the increasing import dependency of Natural Gas in China (32%
in 2015 and 36% in 2016), fulfilling this ambitious target requires the country to
advance further into new regulatory and commercial business models in Natural
Gas in order to ensure Natural Gas is a competitive alternative to coal and other
fuels in power generation.

Obstacles to Cost-competitive Natural Gas-fired Power Generation
Although there is plenty of natural gas in the global market, gas fired power
generation in China is still expensive. The LCOE (Levelized Cost of Electricity)
for Gas fired power generation is ~0.8 RMB/kWh, 2.5 times of coal. Although low
and stable gas prices can incentivize more gas-fired power in mid to long term, by
far low gas price is still difficult to pass through to gas fired electricity prices.
Main obstacles are:
• Power generators lack access to midstream infrastructure (eg.
regas
facilities)
• Fuel costs and on-grid tariffs are regulated
• Grid companies decide on power dispatching
3.“Gas to Power”: A systematic and holistic approach for Gas fired Power
Generation
Sourcing the future supply of natural gas and achieving price competitive Gas
fired power generation calls for leveraging best practices from other countries and
employing a holistic approach to integrate the Gas to Power Value Chain
(hereafter referred as G2P Value Chain) i.e. connecting the dots between Gas Sales
Agreement (GSA) and Power Purchase Agreement (PPA) instead of merely
focusing on upstream or downstream power generation. Taking LNG to power as
Integration of the natural gas value chain into power generation
Siemens AG All Rights Reserved©
an example, the G2P Value Chain comprises gas transport, liquefaction, shipping,
regasification and pipeline, transportation. Among the total LCOE of CCPP,
around 75% of the cost comes from the fuel, i.e. Natural Gas. Therefore it is
vitally important to take a holistic and systematic approach on the G2P Value
Chain to ensure access to the least cost of delivered natural gas, while securing a
sustainable gas supply in order to enable the quick expansion of a price
competitive Natural Gas fired power generation market in China.
Best Practices World Wide
Various countries are taking efforts to optimize their G2P Value Chains, e.g.
Mexico, Brazil, Pakistan, Egypt and Morocco, just to name a few, have diversified
their supply sources combining domestic resources with energy imports in an
effort to optimize their G2P Value Chains. Even though Morocco has had access
to natural gas via pipeline from Algeria, (soon to be terminated), the Government
is committed to develop more than 5 GW of new combined cycle power
generation with imported LNG. The new power generation plants will support a
LNG regasification facility on the coast which will further enable the development
of local natural gas distribution networks for residential, commercial and industrial
use.
Integration of the natural gas value chain into power generation
Siemens AG All Rights Reserved©
Another best practice is that open-access LNG regasification terminals could
provide supply flexibility and efficiency to both generators and industry. Brazil,
abundant in Hydro power, has little or no underground gas storage and thus LNG
regasification terminals have served to provide fast natural gas supply to power
generators during periods of low rainfall to make up for the lack of run-of-theriver
hydro generation.
Since 2013, Mexico has undergone a transformation of its energy sector.
Looking to introducing efficiency and bringing down energy costs, the country has
reformed its Constitution, secondary laws and regulations to allow for open
competition in wholesale marketing and transportation of natural gas. Private
companies can import natural gas from the U.S. via pipelines or import LNG by
developing open-access regasification terminals. Hence, they can offer alternative
natural gas supply to power generators and industrial consumers to that of
Petróleos Mexicanos. The transportation and storage of natural gas remain a
regulated activity by the Government but the development of new infrastructure is
possible by obtaining the necessary permits and approvals. The ability to develop
competitive infrastructure becomes critical when small power generators benefit
from a common natural gas infrastructure optimizing the resulting cost of
electricity.

Finally, Malta provides a more recent example of a successful integration of
the G2P Value Chain. The local utility, Enemalta, ran a tender process to select the
best supplier of electricity and natural gas under long-term agreements. Siemens,
together with other team members, submitted the winning proposal whereby a
special purpose company would install a 200-MW combined-cycle power plant
underpinned by a new floating storage LNG (FSU) vessel of approximately
130,000 cubic meters in size. It’s worth noting that the regasification section of the
LNG terminal is onshore and separate from the vessel. Once in operation, Malta
will import about 1 LNG cargo per month to fuel the power plant and to supply
gas to neighboring demand centers. The uniqueness of this G2P integrated solution
is that not only this infrastructure project was financed on a stand-alone basis
using the existing regulatory and commercial frameworks set-up by the
Government of Malta and Enamalta but also by the close thermal integration
between the power plant and the regasification section. By cooling the air intake
into the combustion turbine, Siemens and its team members were able to extract
approximately 7% additional capacity and energy with the same fuel consumption.
Further, the development team used some of the cooling available in the
regasification section to reduce the intake of seawater for the steam turbine
condenser and have a more environmentally friendly operation.

Implications for China: Integration of G2P Value Chain
There are various players along the G2P Value Chain, e.g. IOCs, NOCs,
LNG Equity suppliers, Liquefaction players, shipping companies, traders, Power
IPPs and government Utilities. The dramatic change in Oil and Gas industry sees
new trends in both upstream and downstream gas.
In downstream, power offtakes are focused on guaranteeing PPAs, and fuel
supply strategy becomes more necessary and critical for project sanctioning. In
upstream, LNG suppliers are willing to provide development capital, sweat equity,
and equity financing to secure offtake.
There are increasing demands for ―business model integration‖ to connect the
up/midstream Gas project development (e.g. Liquefaction plant) with the
downstream power generation project to make bankable power projects by making
best use of capitals from various sources. There is also increasing demand for
―technology/System Integration‖ providing lower costs for the whole G2P Value
Chain from liquefaction, transportation (pipeline or shipping) to regasification,
power generation, and electricity transmission and distribution to reduce cost and
to improve overall efficiency, availability and performance.

Figure 2. Siemens portfolio for the whole G2P Value Chain
For LNG, by utilizing advanced technologies, modular designs, and a proven
track record, Siemens is capable of providing a range of liquefaction technologies
including Micro LNG (up to 0.003 MTPA), Medium LNG (0.1-2.0 MTPA),
Floating LNG, and large LNG (>2.0 MTPA). For example, the Russia Yamal LNG
project in which CNPC owns 20% share and China's Silk Road to purchase 9.9%
stake, Siemens designed and supplied the world’s biggest (90m x 36m) and
heaviest (2,500 MT) single lift E-House module (29 E-Houses total) for electrical
power distribution incl. power island, GT genset (SGT800) and BOG compression
into harsh environment (perma-frost conditions).

In addition to the conventional gas turbine driven Liquefaction solutions,
Siemens developed an all-Electric Drive solution (eLNG) which benefits clients
via:
• Enhanced safety in operation. About 10 days of additional production
per year
• Continuous operation over a long period (6 years on stream possible)
• Capacity of LNG train can be designed to match exactly market
requirements
• Restart losses after plant trip can be reduced to minimum
• Shorter delivery schedule
• Lower CAPEX when a grid connection is available
For gas fired power generation, high efficiency power plants using
advanced gas engines or gas turbines are the key decisive factors to achieving the
grand mission of gas fired power in China. Taking gas turbines as an example;
advanced gas turbines include small (<16MW) and medium (16-60MW) size gas
turbines for distributed power generation, and large size gas turbines (>60MW) for
centralized power generation.
Ranging from 142KW to 420MW gas engine/turbine (see figure 3), Siemens
Integration of the natural gas value chain into power generation
Siemens AG All Rights Reserved©
has a complete range of gas engine/gas turbine technology in its portfolio. This
includes a strong expertise across all power generation applications, including
Distributed Energy (DE), Combined Heat and Power (CHP/COGEN) and
Combined Cycle Power Plant (CCPP). Proven experience and reliability in power
supply is a key prerequisite for future economic development. Siemens has
experience on approximately 3,000 sets of gas turbines and 2,700 sets of Gas
Engines for power generation (including more than 1,400 sets of small and
medium gas turbines, and over 1,500 sets of large gas turbine globally, as well as
more than 260GW of large size CCPP).
As one of the leading operating examples for Siemens advanced gas turbine
technology, Siemens 8000H gas turbine is one of the most powerful, efficient, and
advanced large size gas turbines in the world. On January 22, 2016, Siemens
handed over the combined cycle power plant equipped with a Siemens 8000H gas
turbine at the Lausward location in the Düsseldorf (Germany) harbor area to the
customer and operator, the utility company Stadtwerke Düsseldorf AG (see figure
4). The turnkey plant sets three new records in world-wide comparison. During the
test run before acceptance, unit "Fortuna" achieved a maximum electrical net
output of 603.8 megawatts (MW), which is a new record for a combined cycle
plant of this type in a single-shaft configuration. A new world record of around
Integration of the natural gas value chain into power generation

61.5% for net power-generating efficiency was also achieved. In addition, unit
"Fortuna" can also deliver up to around 300 MW for the district heating system of
Düsseldorf. The overall natural gas utilization achieves 85%, and CO2 reduction
to amount to 2,500,000 Metric Tons per annum. (see figure 5)
In January 2017, Siemens received the first 8000H Gas Turbine order in
China, and has now sold a total of 80 sets of SGT-8000H worldwide. The order
from China being the Castle Peak Power Co. Ltd. (CAPCO) project for the
delivery of a power block for a new combined cycle unit in its Black Point Power
Station in Tuen Mun, in the northwest of Hong Kong. CAPCO is a joint venture of
China Southern Power Grid International Limited and CLP Power Hong Kong
Limited (CLP Power). Scheduled to be in operation before 2020, the plant will
have an installed total capacity of more than 560 MW to supply approximately a
million households with electricity.
Since 2003, Siemens has been successfully cooperating in technology of large
sized gas turbine (E, F and H-class) with its strategic partner in China, and
supplied closed to 60 sets of E and F-class gas turbine for China with
manufacturing in Joint Ventures, and for some export projects as well.

5.Siemens Recommendations
China has set the direction for energy revolution to secure the energy supply
for high efficiency, green and clean energy under open condition by means of
1 HSSE - Health, Safe, Security, Environment
Integration of the natural gas value chain into power generation

letting ―the market play a decisive role in the allocation of resources‖. To ensure
sustainable, cost-effective gas supply and speed up the development of gas power
generation, Siemens believes the holistic approach for an integrated Gas to Power
Value Chain from both the business model perspective and technology perspective,
will definitely help China achieve its ambitious goal in energy revolution. Siemens
would like to recommend the following aspects to be specially noted for Chinese
government:
1) Encourage projects aimed at building up integrated G2P Value Chain
utilizing upstream, midstream, and downstream resources at home and abroad,
private and state-owned or mixed ownership from both a business model
perspective and a technology perspective
The global supply of Natural Gas is plentiful, and LNG adds liquidity of the
market and improves the accessibility of cheap gas worldwide. Natural Gas price
is attractive in the mid to long term. More open opportunities (technology,
financing, resource etc.) will emerge when connecting the dots along the G2P
value chain. It will facilitate the effective and comprehensive use of social capitals
and speed up energy reform.

2) Improve Third Party Access to midstream SOE(State Owned Enterprise)
owned facilities, and ease approval of LNG Regasification Terminal construction
for Non-NOCs
Midstream facilities include Regasification Terminals, Gas Pipelines, and Gas
Storages etc. At present most of them belong to NOCs , third party companies,
private or other SOEs are difficult to gain access to necessary facilities to import
oversea cheap LNG. Further opening and speeding up Third Party Access or
easing approval of Non-NOC LNG Regasification Terminal construction will
attract more players and help boost downstream gas applications.
The ultimate goal is to form positive competition among NOCs and Non-NOCs.
3) Define measures and take timely actions to encourage current gas power
enterprises to make full use of the advantages of gas power
Currently, quite a number of large CCPP’s in China do not have enough
operation hours for power generation, and the development of distributed gas
power in China also missed the target set in 12th
FYP. Therefore Siemens proposes
to timely take appropriate measures in terms of gas supply, feed-in tariff and active
co-ordination of the grid to encourage full use the advantages of gas power.
4) Strengthen economics of gas power generation via feasible market
mechanism, e.g. to deregulate pricing in gas and electricity to enable effective

business model construction, and speed up the electricity dispatching reform to
shorten the time to build up the market mechanism for Natural Gas
This includes, for example, establishing healthy pricing model for gas,
reasonable feed-in tariff mechanism and suitable subsidy system. Additionally,
quantifying the environmental cost, such as CO2 trading system in midterm, could
speed up promotion of environmental friendly (low greenhouse gas, low haze) and
high efficient gas power generation.
5) Accelerate the reform of electricity dispatching etc. that encourage gas
fired peaker and CHP applications
Including accelerating reform in access to grid, feed-in-tariff, electricity
selling and mixed ownership, especially for gas fired peaker and CHP applications
6) Adopt the most advanced technology on the whole Gas to Power Value
Chain
With years of development globally, the gas liquefaction, regasification, and
power generation technologies in the world are getting mature. Some of the most
advanced technologies are now well proven and in good deployment with low
emission and high efficiency, such as Siemens e-LNG solution with an all-electric
drive configuration, the advanced, highly efficient and proven Siemens H-class gas

turbine, the advanced high efficient small and middle size gas turbine for
distributed energy, the high efficient once-through HRSG1, the optimized CCPP
and COGEN system, Siemens Digitalization Portfolio, methodology and tools for
life cycle economic evaluation, etc. Through application of these well proven
advanced technologies, China may maximize the benefits brought by integrated
G2P Value Chain.
7) Further opening of Chinese market may encourage international
companies with advanced technologies in planning, system design, engineering,
key equipment manufacturing (e.g. Gas Turbine), service and R&D to further
enter into China, and cooperate with Chinese companies in various ways.
Siemens believes the recommendations may bring more benefit and energy to
the long term successful development of the Gas to Power Value Chain in
China.
