Memorandum submitted by RWE npower
KEY MESSAGES
Secure and affordable energy supplies
need diverse energy sources and coal will continue to be a major
global fuel source for the foreseeable future.
To meet its climate and energy policy
goals, the UK electricity sector faces a massive new plant build
challenge and developing new coal power plants would provide fuel
diversity, while at the same time providing the potential to accelerate
CCS development and deployment.
The cost of delivering climate change
targets will be minimised if market mechanisms such as the EU
ETS send clear long term signals and provide a stable policy framework
to underpin investment.
Mandating CCS to fixed timescales
ahead of commercial scale demonstration will deter and delay CCS
development.
EUETS is the mechanism best suited
to supporting CCS over the longer term. The immediate priority
has to be to ensure the availability of sufficient funds at UK
and EU level to allow the early commercial-scale demonstration
of a range of CCS technologies.
ABOUT RWE NPOWER
1. RWE npower, a division of the RWE Group,
is a leading integrated UK energy company. We supply gas and electricity
to more than 6.5 million customers in the domestic and business
sectors through our retail business npower. We operate and manage
our portfolio of more than 10,000GW of flexible, low-cost coal,
oil and gas-fired power stations and are one of the foremost developers
and operators of industrial combined heat and power (CHP) in the
UK. npower renewables is a market leader in renewable energy dedicated
to generating electricity using sustainable, environmentally-friendly
resources.
2. RWE npower is developing options for new
coal-fired power stations at Tilbury in Essex and Blyth in Northumberland
and has submitted environmental "scoping documents"
for both projects to BERR ahead of making applications under Section
36 of the Electricity Act. We are also designing and building
the UK's first "carbon capture technology" pilot plant
at Aberthaw Power Station. We have applied to pre-qualify for
the Government's competition to demonstrate commercial-scale Carbon
Capture and Storage (CCS) technology, scaling up to at least a
100MW demonstration plant which would form part of the new power
station at Tilbury.
ROLE OF
COAL IN
THE UK ENERGY
MIX
3. Maintaining diversity of energy sources
is critical to meeting the key objectives of UK energy policy
in relation to security of supply, affordability and achieving
climate change targets. Against the current background of steeply
rising oil and gas prices, flexible coal-fired generation plant
continues to play an essential role in meeting electricity demand
in the UK. At the global level, new coal-fired generating capacity
is a major contributor in satisfying the growing energy needs
of major developing economies such as China and India.
4. The Energy White Paper (EWP) published
in May 2007 states that:
"Coal will continue to play a significant
role in global electricity generation for the foreseeable future,
partly because it is the most abundant global fossil fuel but
also because it brings security of supply benefits. For example,
coal-fired generation is a flexible electricity source that can
respond effectively to changing levels of demand. It also helps
to maintain a diverse energy mix." We agree with this strategic
assessment and note that all the energy projections for the UK
that support the EWP indicate a significant level of coal based
generation.
5. Even as the target levels for renewable
energy increase above those assumed in the EWP to meet the ambitious
carbon reduction and renewable energy goals being set under the
EU's Climate Change and Renewable Energy Action Package (the "Green
Package"), there will be a growing need for a diverse energy
generating portfolio that can respond rapidly to fluctuations
in both demand and supply, particularly if the majority of the
UK renewable energy is to come from fluctuating sources such as
wind and tide, coupled with inflexible base-load nuclear generation.
6. Existing and developing environmental
legislation will mean the closure of most, if not all, existing
coal power stations by around 2025. It is important to recognise
that if no new coal plants are built then the UK will be entirely
dependent on imported gas to fulfil the role of flexible and reliable
power generation.
7. Modern super-critical coal-fired power
generation plant is considerably more efficient, operating with
thermal efficiencies of up to 47% compared with existing UK plant
which typically achieve efficiencies of around 35%. Consequently,
new coal-fired plant can deliver CO2 reductions of 20-25% on a
like for like basis without the use of carbon capture and storage
technology.
STATUS OF
CCS TECHNOLOGY
8. CCS is a new technology to the power
industry and there are many unknowns in terms of technical performance,
costs, reliability and risk that need to be overcome if the technology
is to be demonstrated at commercial scale. Until this happens
it cannot be considered as an abatement technique that can be
mandated by legislation on any fixed timescale. If it is mandated
before then the likely result will be no new coal build as investors
will be deterred by the high risk of creating stranded assets.
Whilst this may seem attractive to some it will deter and delay
CCS development. Operators of existing coal plants will not be
easily persuaded to invest in CCS at existing sites that are inefficient
by todays standards and approaching the end of their life. The
successful development of CCS and its subsequent rapid deployment
could be a vital part of delivering the twin long term goals of
carbon reductions and security of energy supplies. This will be
achieved fastest if new coal capacity is delivered in parallel
with the development of CCS.
9. In this regard, RWE npower has developed
a three phase R&D programme:
Test facilityRWE npower is currently commissioning
a test facility at its Didcot power station for evaluating both
oxyfuel and post combustion capture.
Pilot plantRWE npower plans to design
and build the first carbon dioxide capture pilot plant at a UK
coal power station. It is anticipated that the plant will be fully
operational by 2010 and will be located at Aberthaw Power station
in South Wales. The pilot will enable RWE npower to develop a
full understanding of both the technical and commercial issues
relating to CCS and will allow the CCS concept to be tested in
as close to real operational conditions as is possible.
Demonstration plantRWE npower is planning
further investment to support a capture and storage demonstration
plant which will be located at Tilbury power station. This plant
will act as a crucial test-ground for the potential of CCS technology
as a means to generate low-carbon energy.
SUPPORT FOR
CCS DEMONSTRATION
10. The recent Stern Review highlighted
the strategic role that CCS technology could play globally to
lower carbon dioxide emissions with a potential to contribute
up to 28% of global carbon dioxide mitigation by 2050.
11. The European Council has agreed that
Europe should aim for all new fossil fuel power generation built
beyond 2020 to be equipped with CCS, subject to the technology
being technically and commercially feasible. It has also recommended
that the Commission work towards a series of up to 12 CCS demonstration
projects by 2015. To facilitate the deployment of CCS in the UK
and internationally the Government has announced its intention
to launch a competition for demonstration of CCS.
12. RWE npower welcomes the Government support
for a post combustion capture demonstration project and in this
regard has submitted a proposal into the pre-qualification phase
of the Government's CCS demonstration project. However, there
is a need to recognise that the industry in the UK and across
the EU is seeking to develop a range of CCS technologies including
oxyfuel and Integrated Gasification Combined Cycle (IGCC) and
support mechanisms need to address this issue, otherwise the opportunity
to assist with the timely development of these technologies could
be missed.
DELIVERING CLIMATE
CHANGE GOALS
13. RWE npower supports the UK Government's
aim to demonstrate international leadership in mitigating the
impacts of climate change. The UK has signed up to challenging
targets for 2020 in terms of EU greenhouse gas emission reduction
and renewable energy targets. However, in order to deliver these,
the electricity industry urgently needs a long-term stable policy
framework to underpin the significant investments that are needed
in new capacity and transmission infrastructure.
14. The principle mechanism for delivering
carbon reductions in the EU is the EU Emissions Trading Scheme
(EU ETS). With adequate political support by Member States to
deliver a robust framework post 2012, this has the potential to
deliver the required decarbonisation of the energy supply chain
at least cost. Although it should not be the role of the EU ETS
to support emerging technologies such as CCS through the research,
development and demonstration stages, it can be expected to remunerate
them when they achieve commercial availability, provided the technology
cost is lower than that signalled by the carbon market. Only by
utilising technology neutral market mechanisms such as the EU
ETS, coupled with addressing the barriers to delivery, such as
planning, transmission access and R&D support, will the necessary
greenhouse gas emission reductions be achieved with optimum economic
efficiency.
15. The key to delivering the 2020 climate
change goals is timely investment and the major challenge for
the energy sector is in deciding what to invest in. Given the
very high UK renewable energy target implied by the EU Green Package
and known coal, oil and nuclear plant closures, it is quite credible
that the new build requirement in the period between now and 2020
will approach today's total installed capacity, some 70-80 GW.
In order to minimise risk, investors value stable regulatory frameworks
and clear long term price signals. In the current revision of
the EU ETS, there is potential to provide both of these. Given
a robust trajectory for binding carbon emission reductions, clearer
price signals will emerge and energy investors will be able to
select a range of investment options to manage the range of energy
market risks.
16. The UK Government's energy strategy
is based on utilising competitive markets to deliver ambitious
carbon reductions, whilst maintaining security of supply and ensuring
every home is adequately and affordably heated. The EWP rightly
identifies the EU ETS as having a central role in the delivery
of this strategy.
17. Some stakeholders advocate the need
for mandatory CCS on new coal-fired power plant. Given, the current
status of the technology, coupled with the need to ensure adequate
provision of storage and transport infrastructure, we believe
that this is inappropriate for the foreseeable future. It is likely
to have the adverse effect of deterring and delaying CCS development
damaging the prospects for the technology within the UK and the
EU, and also at the global level, where deployment is critical
if developing countries are to address the issue of rising greenhouse
gas emissions from the use of coal as a key energy source. The
immediate priority within the UK and at EU level has to be to
ensure sufficient funds are made available to allow the early
commercial-scale demonstration of a range of CCS technologies.
"CAPTURE READY"
POWER STATIONS
18. The term capture ready has been developed
to describe the ability to retrospectively fit CCS technologies
to future new power station builds. But without being prescriptive
with regard to the CCS technologies applied, it is not practicable
to describe in detail what "capture ready" means. Until
such time as CCS technologies are developed to commercial scale
we believe it would be counterproductive to develop and impose
detailed and restrictive requirements on "capture ready"
plant.
19. However, we fully accept that any operator
contemplating new coal build must expect to either fit CCS in
the future once the technology has been proven at commercial scale,
or alternatively, to operate the plant in a more carbon constrained
manner. The choice will depend on the cost of applying the abatement
technology and the value of the carbon abatement it offers. The
operator is therefore incentivised to make whatever arrangements
they can to minimise the cost of future CCS retrofit. If they
do not, then their future choices will be even more limited.
20. Essentially the main considerations
are space on site for the necessary plant to capture and compress
CO2, the ability to couple this into the proposed power plant
and the potential availability of a route to transport the CO2
away from site into long term storage. Operators have to apply
best available techniques (BAT) to minimise the environmental
impact of power stations and there can be no justification for
imposing tighter environmental emission standards until it is
proven that affordable techniques exist to achieve them.
