In our response to the second Review of Electricity Market Arrangements consultation, we welcome the decision to drop nodal Locational Marginal Pricing and a Split Market and recommend now dropping zonal pricing.
Along with many organisations, Regen has submitted its response to the Review of Energy Market Arrangements (REMA) second consultation.
Our response welcomes the publication of the second REMA consultation as an important milestone towards the development of an efficient GB electricity market and expresses Regen's appreciation of the work done by the REMA team and the progress that has been made.
The response is in two sections:
In most key areas of the Regen response, we are supportive of the overall REMA direction of travel and the options that have been proposed, including the decision to drop nodal Locational Marginal Pricing and a Split Market option.
The main difference of view, which is shared by the majority of companies and organisations working in the energy sector, is a firm recommendation that DESNZ should drop the zonal pricing option to reduce investor uncertainty and enable resources to focus on other more workable solutions.
The rationale to drop zonal pricing, after two years of REMA development, is that:
If DESNZ decides to keep zonal pricing as an option, then a lot more work is needed before any design decision can be made. This additional work includes:
Regen's view is that the benefits of an efficient energy market, and REMA's four challenge objectives, can be better and more quickly achieved through a programme of Progressive Market Reform, based on the foundation of the current national trading market arrangements.
We have set out some of the key pillars of a progressive market reform agenda in our consultation response and will shortly publish a position paper on this subject. Key areas for reform include:
Regen will continue to work with the REMA team and our industry colleagues over the coming months and we welcome any feedback on our consultation response.
We welcome the decision to drop nodal LMP and Split Market.
We recommend now dropping zonal pricing, or relegating this to a counterfactual, and instead focusing resources and effort on developing a progressive reform programme to enhance the national trading market.
If DESNZ decides to retain zonal pricing as an option there is an urgent need to address a number of concerns, clearly defining a set of viable design options, presenting amore robust and credible cost and benefit analysis with realisitic assumptions and address the implications for consumers and distribution-connected assets.
There are significant opportunities for operational reform within a progressive reform programme including in areas such as; constraint management, the balancing mechanism and ancillary markets and the operation of interconnectors.
The issue of locational signalling for investment and asset siting can be addressed through better strategic planning and more direct locational signals through, for example, network charging, connections, leasing/planning, balancing and flexibility markets and revenue support schemes.
We support the proposals to retain and enhance the use of CfDs and Power Purchase Agreements. Both can play a complementary role to accelerate investment and pass the benefits of low cost renewables to consumers.
REMA could be more ambitious in other aspects of consumer value including reforms to help to address fuel poverty, fairness for consumers and to promote local energy supply and local Green Power Pools.
We agree that a deeming option for CfDs could reduce investment risk and market distortions and should be developed with consideration of its potential unintended market impacts, including for other generators and flexibility providers.
We are supportive of the proposal to take forward a single Capacity Market auction with multiple clearing prices and minima procurement target for desirable characteristics, provided it is based on an ambitious low-carbon flexibility target. More detail is needed on how this would work in practice.
More needs to be done to incentivise the conversion of fossil fuel plants to low-carbon technologies and to manage the decommissioning of unabated fossil plants outside the market while ensuring energy security.
The Electricity Storage Network has also submitted a response and Regen has co-authored a response on behalf of 52 local authorities that are participating in the Innovate UK Net Zero Living Thriving Places project.
