Is REMA the answer to the Energy Crisis?

Record high prices and looming net zero targets have pushed the UK government to launch The Review of Electricity Market Arrangements (REMA) as ‘biggest electricity market shake up in decades’. I recently shared an overview of the key REMA proposals and the challenges ahead for Winter 2022-23 to help address the question, is REMA the answer to the UK’s Energy Price Crisis?

Over the last month, BEIS have launched a major review of the UK’s electricity market arrangements, known as REMA; National Grid ESO published their latest Future Energy Scenarios report and most recently their Winter Outlook for 2022/23, highlighting the potential tight supply margins and price spikes ahead; and Ofgem has confirmed that the Default Tariff Price Cap will be set quarterly, to better reflect the costs of the wholesale market.

Meanwhile, we've witnessed significant wholesale price volatility as a result of Russia's gas curtailment to the EU and limited availability of French nuclear supplies. We have already seen the initial impact of these factors as the energy crisis has moved at pace over the last year, driving Winter 22 base prices up from less than £100/MWh in August 2021 to over £500/MWh at the beginning of August 2022 (based on the forward seasonal prices). 

What is REMA and is it the UK's silver bullet?

The Government has launched REMA to pave the way for what it said could be the biggest reform of the electricity market in a generation to improve security of supply and cut prices.

Possible changes under the Review of Electricity Market Arrangements (REMA) include decoupling gas prices from the wholesale electricity market, reforming the Capacity Market to attract low carbon flexibility technologies, and introducing incentives for consumers to use energy when demand on the grid is lower.

BEIS said it wanted the review to radically reduce the country’s exposure to volatile global gas markets and to cope with an expected doubling in electricity demand over the next 13 years. Energy Secretary Kwasi Kwarteng said: “In what could be the biggest electricity market shake up in decades, I am confident that this review will significantly enhance GB’s energy security and supply for generations to come.” The consultation on the review is open until the 10th October.

As SmartestEnergy prepare for an unpredictable winter, REMA set out positive steps to support UK energy consumers from a price and security of supply perspective, but any market reform will be up against unprecedented external market factors driving extreme price volatility.

Additionally, as reported in the industry press, there are a number of challenges facing REMA, such as the infrastructure needed to achieve the 150% increase in capacity of UK generation by 2035.
