Select Committee on Treasury Written Evidence


Memorandum submitted by EDF Energy

  Our response focuses on the following areas of the committee's inquiry:

    —  the use of environmental or green taxes that are specifically targeted at climate change;

    —  the extent to which government uses environmental taxation to encourage behavioural change; and

    —  looking forward, the appropriate role of environmental taxation in the context of the range of means that Government can use to achieve its environmental policy aims—for example by means of regulation, voluntary agreement or a spending measure.

1.  CLIMATE CHANGE POLICY AND THE EXISTING FRAMEWORK OF INSTRUMENTS

  1.1  The nature of climate change and its importance places a huge responsibility on all areas of society to address its impact. One of the key challenges for the UK is to develop a comprehensive climate change programme that engages all areas of society, specifically targets greenhouse gas emissions and efficiently incentivises reductions in Greenhouse Gas (GHG) emissions over time to the required level.

  1.2  Whilst the existing programme is extensive, currently the UK's climate change policies do not fully address the continued growth in emissions from, in particular, the transport sector. Emissions from gas use associated with space heating are also largely uncapped. This contrasts with the cap on emissions (at an EU level) placed on the electricity generation sector via the EU ETS.

  1.3  Whilst energy efficiency measures are desirable (e.g. agreements with motor manufacturers, appliance labelling, EEC, etc), where appropriate the best way to ensure GHG emission reductions is to place a cap on them. The long-term appropriateness of measures such as Climate Change Agreements (CCAs), which control emission intensity but do not cap absolute emissions, will need to be reassessed.

  1.4  Existing policies covering the energy industry (UK ETS, Climate Change Levy (CCL), CCA, Levy Exempt Certificates (LECs), EU ETS, Energy Efficiency Commitment (EEC), Renewables Obligation (RO) and the proposed Energy Performance Commitment(EPC)) have different carbon prices embedded in each instrument. The variation and complexity in coverage and carbon price create a number of anomalies and effects. For example:

    —  domestic consumers using electricity for space heating are exposed to a carbon price via the internalisation of EU ETS CO2 prices in electricity costs, whereas those using gas for the same purpose have no exposure to carbon price;

    —  renewable generation benefits from three climate change instruments—LECs, the RO and the internalisation of EU ETS CO2 prices in electricity prices; and

    —  some organisations will have elements of their activities regulated by EU ETS and CCAs, pay CCL on energy use associated with other activities, have another CO2 cost internalised in their electricity prices as a result of EU ETS and potentially for activities not covered by EU ETS be within scope of the EPC.

  1.5  The complexity and discrepancies illustrated in the few examples above indicate that there is a need to review, and where appropriate streamline and harmonise, climate change policies to ensure delivery of specifically targeted greenhouse gas emissions reductions in an efficient manner. At this stage, what remains unclear is the likely longevity of individual measures and the government's ambition for the overall long-term mix of instruments to deliver its required level of GHG emissions. For example it is unclear whether it is government's intention to have a single economy-wide CO2 price or rather that, even in the long-term, there will be a requirement for different carbon prices/measures to apply to different sectors.

  1.6  The Government will also need to carefully consider the implications and structure of the proposed statutory targets in the Climate Change Bill to ensure that they are consistent and compatible with other UK and EU policy instruments.

  1.7  Schemes which create a carbon price do have the potential to create behavioural change. The EU ETS has had mixed success in this respect. The UK power sector has internalised the opportunity cost of carbon in decisions to generate/not generate electricity from individual power stations on a half-hourly basis. Other sectors, which receive business-as-usual allocations, have generally not internalised the cost in their operational decision-making processes. This demonstrates that the presence of a carbon price alone is not necessarily sufficient to create behavioural change but that other aspects of scheme design are also important in incentivising the correct behaviours, such as the level of auctioning of allowances.

2.  DEVELOPING A MECHANISM TO DELIVER CAPITAL INVESTMENTS UNDER THE EU ETS FRAMEWORK

  2.1  EDF Energy supports the development of emissions trading as the key part of the UK and Europe's strategy for reducing emissions from industry across the UK and Europe. A well designed and properly functioning emissions trading scheme provides a means of delivering emissions reductions at least cost, through the creation of an efficient and transparent market in emissions allowances. By placing a price on current and future emissions it should in theory incentivise industry to either improve its energy efficiency, invest at scale in technologies using low-carbon fuels, or to develop innovative low-carbon technologies.

  2.2  To make this work, the long-term stability of the EU ETS is crucial for existing participants to have the confidence to invest in abatement technologies and make significant emissions reductions, and for the EU ETS to develop into a global market. The EU ETS, as presently constituted, is not capable of sending the signals required to deliver investment in lower carbon technologies in the UK and EU, as a result of the political and regulatory uncertainty surrounding future carbon dioxide abatement targets and the structure of EU ETS beyond 2012. Although considerable efforts are being made to agree long term abatement targets across the EU, these are unlikely to be agreed in the near future. Furthermore, it is unclear how such a target would be split between the traded and non-traded sectors. This uncertainty creates a significant hurdle for early investment in low carbon technologies. We believe that the key priority for Government should be to provide political certainty for investors in future carbon dioxide abatement targets. Investment over the next 10-20 years will have a profound effect on UK emissions over the lifetime of these assets, which varies between 20 and 60 years, depending on technology.

  2.3  The EU ETS currently does not provide equivalent treatment of new investment in low carbon technologies, such as carbon sequestration and nuclear, relative to new fossil fuel installations. Although these low carbon technologies benefit from higher electricity prices driven by carbon prices in the EU ETS, the provision of free allocations to new fossil plant provides a subsidy to CO2 emitting plant[43] relative to low carbon plant. Also, the present time scales of the EU ETS and the visibility and certainty of future carbon prices does not match the investment life-cycles of these assets.

  2.4  Without the provision of additional certainty to investors, there is a risk that the necessary low carbon technology investments to deliver the government's GHG reduction targets will not occur or at the very least will be delayed significantly. Instead there will be investment in fossil plant, thereby locking the UK into higher levels of emissions.

  2.5  The options available that can reinforce the operation of the EU ETS, in order to support investments in low carbon technologies in the generation sector include:

    —  carbon tax;

    —  carbon generation obligation;

    —  contracts for purchasing carbon reductions; and

    —  contracts for differences securing a minimum value for carbon abatement—namely, Carbon hedges.

  2.6  Carbon Tax—A carbon tax offers government certainty over the cost of targeting carbon reductions, but not the outcome in terms of the volume of those reductions. If the tax is set at the right level, then reductions will be achieved, but the level that is correct is unlikely to be observable by government. For investors, a tax does not give long term certainty over the value of carbon, as taxes can change every year, particularly if the government believes that the tax has previously been set at an incorrect level.

  2.7  Carbon Obligation—A carbon obligation certainly offers incentives for investment, and the Renewables Obligation has delivered much greater levels of renewable generation than would otherwise have occurred. Potentially such obligations may require the government to pick technologies and the extent to which such technologies should be a part of the overall generation mix. Also, as has been found with the RO, some technologies may come to dominate under an obligation, and the government may come under pressure to change the rules and pick different winners. Obligations may not allow the market to find the most efficient abatement options by which to achieve carbon reduction targets.

  2.8  Carbon contracts have the ability to reinforce and strengthen carbon market mechanisms where, like the current EU ETS, the market mechanism alone does not produce the necessary long-term price signals. The contract gives investors the long term certainty they need, without requiring the government to pick technologies, and can be designed to be consistent with existing policy mechanisms. Such contracts have the further advantage of allowing Government to limit its liabilities under these contracts by controlling the volume of abatement it is willing to underwrite. The government can further limit its liabilities by influencing wider policy development and retaining the carbon price within a reasonable range that minimises its financial exposure. This liability should in any case be set against the real and increasing liability faced by the government if action to address climate change is not taken. A possible problem with a carbon contract is that if the price for carbon remains high, through the EU ETS, then a payment through the contract will be in addition to the carbon element of the electricity price. The solution to this would be to contract only for the difference between the contract price and market price for carbon, as explained below.

  2.9  EDF Energy's preferred option is the Carbon hedge, ie a contract for difference to essentially provide a "floor price" for carbon. If a strong EU ETS phase 3 emerges from international negotiation, as the government intends, the value of carbon will remain an important factor in the electricity market. A carbon price will mean that the cost of carbon is properly reflected in electricity prices according to the level of emissions associated with the production of that electricity. In these circumstances the government would not need to make any payments to the investor, as the investor is already benefiting through the wholesale price for electricity. Only if the price for carbon falls to a low point would the government become liable for payments. Companies wishing to bid for such contracts would competitively bid to the government, so that the level of the floor would be pushed down to the lowest level needed to secure the desired reduction in CO2 emissions. Such a bidding process should be open to all forms of low carbon generation and would be "technology neutral". The government would then have the option of contracting for as much or as little carbon reduction as required to fit with the overall carbon reduction goals.

  2.10  EDF Energy believes that commercial market-based instruments can be used to underpin the significant capital investment required to lower the carbon intensity of the electricity sector in the UK. This can be done without exposing the UK Government to unacceptable financial risks by controlling the amount of CO2 reductions it commits to in this way. These instruments can be designed to reinforce the integrity of the EU ETS and global carbon market in the long term, within the framework of competitive and liberalised energy markets, as supported by the UK Government.

43   The level of subsidy will be dependent upon the level of allocation and the extent to which CO2 prices are reflected in the prices to end consumers. In the UK, the nature of vertical integration in the competitive market means that in practice tariff customers are exposed to the cost of purchasing CO2 allowances to cover generators' short positions rather then the full opportunity cost. Back
