Memorandum by British Energy
SUMMARY OF
KEY POINTS
Overall, there should be greater
focus on the three key objectives of energy policygreenhouse
gas reductions, maintaining security-of-supply, and the provision
of affordable energy for consumersrather than on prescribing
how these objectives should be met at Member State levels.
The UK's national 15% renewable energy
target is extremely challenging, bearing in mind renewable energy
currently contributes just 2% of the total.
The renewable energy target will
be delivered from three sectors: heat, transport and electricity.
Independent analysis suggests that the largest single contribution
is likely to come from the electricity sector, and implies about
40% of the electricity generated in 2020 must come from renewable
sources.
Government interventions on this
scale have far-reaching consequences. Most important is that they
undermine liberalised markets and increase costs to the consumer.
In the context of security of supply,
it is worth noting that the relatively low connectivity of the
UK with mainland Europe means it benefits much less than other
Members States from developments in Europe.
In setting the renewables target,
little account appears to have been taken of alternative lower
cost abatement options in the electricity sector such as nuclear
and fossil generation fitted with carbon capture and storage.
Planning is the biggest obstacle
to connecting renewable generators to the transmission system,
as the recent decision to reject the Lewis Wind Project (which
would have been one of the largest developments in Europe) demonstrates.
This needs to be addressed by the Planning Bill.
The detailed implementation of policies
and measures to deliver the targets and the costs involved have
not been sufficiently considered and could also lead to unforeseen
circumstances such as the undermining of the EU ETS.
In terms of additional infrastructure,
a significant amount of new fossil standby plant will be needed
to cover low renewables production during certain periods of the
year; a significant expansion of the grid network to accommodate
a larger more dispersed generation sector will also be needed.
A significant excess of generation
could exist under periods of high renewable production and low
demand; in this case it will be necessary to constrain off some
plant to maintain system stability.
Member States have indicated they
are willing to take on specific targets and they should be allowed
to develop support mechanisms that best suits their economic circumstances.
DETAILED RESPONSE
TO QUESTIONS
ON TARGETS
How achievable are both the EU's general 20% and
the UK's national 15% renewable energies target?
1. The EU's general 20% and UK's national
15% renewable energy targets are both extremely challenging, bearing
in mind renewable energy currently contributes about 7% and 2%
for the EU and UK respectively. The scale of the challenge is
highlighted in Table 1.

2. It is worth noting that the 2% of energy for the UK
in 2005 in the table above is the result of a policy to promote
renewable electricity through the NFFO and RO schemes since 1990;
also, this figure has a significant contribution by hydro electricity
which was largely built before 1990. Bearing in mind there are
now only 12 years to go before 2020, the original BaU renewables
contribution of 5% would have been difficult to reachachieving
a trebling of this value (ie 15%) would seem unrealistic, even
with heavy handed market interventions and substantial cost to
the consumer.
3. It is proposed that the 15% UK target will be delivered
through three sectors: heat, transport and electricity. In the
specific case of electricity the current 4% contribution by renewables
will need to increase by an order of magnitude to about 40%, to
deliver the UK's commitment under the draft Directive.
4. To meet the level of requirement suggested by the
POYRY (1) analysis of 150 TWh in 2020 means:
A growth rate of 20% per annum is required, twice
the average growth over the period 1998-2006.
An improved planning process, a grid that can
respond to a high degree of variability, and a market structure
that is sympathetically flexible, are issues that need to be successfully
resolved. In the absence of these developments security of supply
and economic well-being will be compromised.
The RO, or any successor support mechanism, would
have to provide sufficient incentive for all renewable technologies,
and in particular offshore wind development.
That supply chain bottlenecks in the renewable
sector must be overcome if the extremely large number of new projects
required are to be delivered in a timely fashion.
A significant amount of new standby plant (ie
non-intermittent, conventional plant) will be needed to cover
low renewables production, for example, during periods of low
wind. There also needs to be a financial mechanism to encourage
development of standby generation, to levels well beyond those
currently in the market.
Excess of generation during periods of low demand
is also a potential problem. Maximum output from the renewables
could be 150TWh per year in 2020. Based on an average load factor
of around 35%, which equates to 49GW of generation capacity in
periods of high renewables yield compared to a low demand of around
27 GW (an excess of 22GW which would need to be constrained off).
If we consider that in addition to this there needs to be thermal
baseload generation (fossil and nuclear), then inevitably we must
assume there would be a significant excess of generation. This
is an important system issue that has yet to be fully considered.
Similar simple calculations show there will need
to be a significant increase in the size of the grid in 2020 with
all the attendant impacts associated with transmission lines,
planning, and cost to the consumer. By way of illustration, assuming
all generation is from thermal sources, 64GW of installed capacity
will be required to deliver the 368TWh demand in 2020; to generate
40% of electricity from renewables, a total of 87 GW is required
(made up of 49 GW renewables and 38GW of conventional thermal
generation) to achieve the 368 TWh demand. The latter scenario
would require 36% increase in grid size. (It is important to
note that this does not include the standby plant needed which
would be significantly higher in the second case).
How coherent are these proposals in the context of the EU's
energy policies in general and the Third Energy Package in particular?
5. It is widely recognised that the "20:20:20"
targets set, for the three areas of energy efficiency improvements,
greenhouse gas reduction, and percentage contribution to energy
consumption by renewable sources, is a huge challenge for Member
States. In particular there are a number of concerns:
Overall, there should be greater focus on the
three key objectives of greenhouse gas reductions, maintaining
security-of-supply, and the provision of affordable energy for
consumers, rather than on prescribing how these objectives should
be met at Member State levels.
The detailed implementation of policies and measures
to deliver the targets, and the cost involved, has not been sufficiently
considered and this has led to considerable criticism amongst
key stakeholders.
There are also potential unforeseen effects. The
emissions trading scheme (EU ETS) is a very effective market mechanism
that can deliver emissions reductions across the economy through
a credible and effective cost of carbon, and provides an important
vehicle to engage with, and facilitate activities outside of the
EU. Forcing industry to deliver the renewables target has two
effects:
The carbon savings would be more expensive than
if they were delivered through the EU ETS.
Emissions reductions through renewables undermines
the need for emissions reductions through the EU ETS, putting
downward pressure on the cost of carbon, thus weakening the incentives
for abatement across the economy.
To what extent are these targets capable of improving the EU's
security of energy supplies?
6. The technologies proposed to deliver these targets
would improve security of energy supply. However, there are two
aspects to security of supply, access to primary energy and variability
of supply; both of these have implications for a modern economy.
There are some important limitations:
Indigenous fossil supplies in coal and to a lesser
extent oil and gas have ensured access to primary energy for most
for the last century. Today, dwindling indigenous oil and gas
resources leaves indigenous coal and nuclear to provide a measure
of secure supplies. Renewables can also contribute to this aspect
of security of supply, although as indicated below, and with the
exception of indigenous biomass, there are significant limitations.
Wind power, the main renewables technology proposed
to deliver the targets, is subject to the vagaries of meteorology
and as such there are periods in which they cannot be relied upon
to deliver the energy requiredbecause of this variability,
significant (fossil) standby plant is required on the system to
ensure provision of electricity. Storage of electricity in the
UK is very limited with hydro electric pump storage as our only
viable form of electricity storage. The greater the wind component
to the electricity system, the greater the standby plant needed,
and the less efficient the overall system.
7. In the context of security of supply, it is worth
noting that the relatively low connectivity of the UK with mainland
Europe means it benefits much less than other Members States from
developments in Europe.
ON GRID
ACCESS
How effective has the existing legislation (2001/77/EC) been
in encouraging grid access for renewable energy generators?
8. The Directive for Production from Renewable Energy
sources has not had any real affect on grid access.
9. The rules for transmission use of system charges in
the UK are the same for all technologies. The current system is
split 20% "locational" and 80% "residual"
ie a wind generator for example, will have to pay 20% and then
the remaining 80% is socialised.
To what extent does grid access remain a significant barrier
to increased consumption of renewable energies? Is it consistently
a problem across all Member States?
10. The speed of implementing upgrades is slow mainly
due to planning and partly due to uncertainties in timescales
for gaining consent for new build schemes and the associated transmission
connected assets.
How does Use of System charging affect grid access for renewable
energy generators? How far can the different levels of renewable
energies take-up in different Member States be attributed to Use
of System charging and cost sharing rules?
11. National Grid Transco has a licence obligation to
promote competition, and thus benefit the consumerto achieve
this goal their charges are non-discriminatory against technologies.
What impact do the various systems of reinforcement planning
and work have on encouraging renewable generation? How important
is the issue of constraint in increasing Member States' renewable
generation?
12. This issue is being considered by National Grid and
by industry. Provision for 100% rated capacity for wind and hydro
could be less cost-effective than dynamic management of the appropriately
sized grid. The Ofgem/BERR transmission access review is ongoing
alongside an industry review of code amendments, one of which
considers sharing of capacity.
To what extent is further co-ordination of National Regulatory
Authorities needed?
13. No comment.
How far do current regulations inhibit access to the grid?
14. The current regulations do not inhibit access, but
planning does have a major impact, not only for renewables but
all competing technologies.
ON SUPPORT
SCHEMES
At what level should the EU be involved in harmonising or regulating
support schemes offered by Member States to encourage renewable
energy generation?
15. Government interventions on this scale have far-reaching
consequences. Most important is that they undermine liberalised
markets and increase costs to the consumer.
16. Member States have indicated they are willing to
take on specific targets and they should be allowed to develop
support mechanisms that best suits their economic circumstances.
17. However, the EU role is an important one:
They should ensure that the level of subsidy provided
does not distort competition across the region; they should also
ensure that when a technology has become "mainstream"
it should no longer receive a subsidy and be allowed to compete
with other technologies on a level playing field.
One idea put forward is to allow a new "renewables
accounting" to emerge in which a technology such as coal
(or gas) fitted with Carbon Capture and Storage is allowed to
count towards renewables targets ie that it has renewable "status";
such an intervention would be a clear indication that the renewables
target was set at too high a level for the timescale involved,
and if this were to go ahead then all low carbon technologies,
including nuclear should be part of this approach.
A framework for any proposed "trading"
of renewables across Member States needs an EU overview so that
its development, were it to go ahead, balances domestic action
with the need for the lowest overall cost solution.
The EU should ensure that the renewable target
should not compromise the drive for truly liberalised marketsthe
latter are at serious risk under the proposed level renewables,
particularly in the electricity sector, if these continue to be
subsidised over the long term.
What impact have the various schemes in operation across the
Member States had on encouraging renewable energy? How have these
schemes affected take-up both by producers and commercial and
domestic consumers?
18. The UK is an island generator with limited electrical
connectivity to Europewe should therefore not draw analogies
from the vast majority of Member States who do not face the same
constraints as the UK.
19. There are a number of lessons learned from the development
of the renewable sector in the EU over the last two decades or
so:
Setting targets, whether indicative or absolute
does mobilise action but they must be complemented with policies
and measures that address the nature and scale of financial incentives,
planning issues, and grid connection.
Governments should avoid picking winnersrather
its role must be to create the financial, planning and technical
regimes that encourage the successful technologies to emerge.
So long as the government provides the enabling framework, the
market will ensure the successful adoption of the most appropriate
technologies.
The German model whereby renewables developers
are guaranteed grid connection and electricity sales at a premium
price has proved particularly effective in delivering operating
capacity. The obligation mechanism, favoured in a number of countries
including the UK, with incentives and penalties, should also prove
effective in this context but perhaps at a much lower overall
cost to the consumer.
Any new legislation must allow the possibility
for polices and measures to evolve because the renewables sector,
as well as some of the key underlying drivers for the industry,
are dynamic, and will continue to be so for some years to come.
It is important to address the institutional support
for any scheme adopted ie the monitoring, verification and administrative
support since this could involve significant additional costs.
Once the financial incentives have achieved their
aim eg cost convergence with traditional players, then these technologies
must be judged alongside the traditional players, otherwise there
is a risk of market distortions.
Competitiveness issues between companies, and
countries, have largely been absent from discussions on the development
of renewables. Such issues are likely to be more prominent as
the renewables sector grows into a significant contributor to
the electricity mix.
The development of national polices and measures
must also reflect international developments in some areas. For
example, there is strong interest in developing a major Green
Certificate market across the EU, and this will provide additional
impetus to the industry. Questions of parity will inevitably arise
with pressure to harmonise policies and measures.
Will cross-border renewables markets be genuinely affected
by the existence of a variety of support schemes? Is necessary
investment hampered by lack of market harmonisation?
20. Support mechanisms for renewable technology deployment
have been developed by Member States to suit their own economic
structure. These technologies deliver a number of attributes to
Member States which they will be keen to retain: electricity and
biofuels for economic activity and social well-being; carbon reductions;
and a measure of security of supply. These interests make the
emergence of a significant cross-border renewable market less
likely, and if this is the case, then a lack of market harmonisation
is less important from an investment standpoint.
To what extent would the enhanced use of Guarantees of Origin
certificates require the harmonisation of support schemes?
21. Further harmonisation of support schemes is not necessary
so long as individual Member State schemes have been scrutinised
by the EC, and Guarantees of Origin adhere to a required "standard".
