As COP26 approaches, Brevia will be tracking the latest milestones in the UK’s preparations for the upcoming climate conference. This week’s developments include a new green record for the GB electricity grid, ‘Clean Power Hub’ developments in the Humber, as well as the construction of a new 2.3MW solar array at the British Army’s Defence School of Transport.


Great Britain’s electricity system recorded a new record for green power this Easter Monday, with the carbon intensity on the grid dropping to 39g of CO2 for every kilowatt-hour of electricity. This surpassed the previous record of 46g of CO2 recorded on the 24 May last year. [1]

Lower than average demand for electricity over the Easter holiday, combined with bank holiday sunshine and high wind output, meant that wind and solar power provided 60 per cent of all electricity. Nuclear plants provided 16 per cent of the electricity mix, taking the total low carbon generation to 80 per cent of the electricity on the grid. [2]

Whilst data from the ESO showed that demand for electricity remained 5 per cent lower than usual, the new record is still an impressive achievement for the country as the energy system continues to move away from fossil fuel reliance.


SSE Thermal and Equinor have unveiled a new partnership to develop two low carbon power stations in the Humber region. The projects include plans for a Carbon Capture and Storage (CCS) power station, Keadby 3, and a hydrogen power station, Keadby Hydrogen. [3]

The two clean energy power stations would form a ‘clean power hub’ and would replace the fossil fuel based generation on the grid by providing flexible and firm power to support the UK’s renewable generation. Keadby 3 could deliver 15 per cent of the UK’s target of 10 million tonnes of carbon capture from gas generation, whilst Keadby Hydrogen is expected to account for a third of the Government’s 5GW hydrogen production target.

The projects are still in the development stages, with final investment decisions depending on the support and policy framework agreed upon. The project is expected to make use of  the hydrogen and CO2 pipeline infrastructure being developed by the Zero Carbon Humber partnership, as well as offshore CO2 infrastructure developed by the Northern Endurance Partnership.


The British Army has announced that it will install its first photovoltaic solar farm at the British Army’s Defence School of Transport (DST) in Leconfield.[4]

Construction of the 2.3MW solar array started earlier this year and is being delivered with support from Centrica Business Solutions. It is expected that the electricity generated will meet a third of the DST’s electricity needs. [5]

The solar array is the first of four pilot sites delivered as part of the Ministry of Defence’s initiative to increase renewable energy across the defence estate and help deliver the 2050 net zero target. Together, the four pilot sites will result in £1-million in efficiency savings and reduce emissions by 2,000 tCO2e (tonnes of carbon dioxide equivalent) per year.[6]

The three further pilots at Duke of Gloucester Barracks, South Cerney, Gloucestershire; Rock Barracks, Suffolk; and Baker Barracks on Thorney Island, Sussex are scheduled for delivery by Summer 2021.

Energy White Paper Audit

Last week Brevia Energy released the findings of its audit of the Government’s 2020 Energy White Paper. The results, which were covered by Energy Live News, highlighted how nearly half of the commitments included in the Energy White Paper have been hit or look likely to be reached. However, the research also showed that answers to the ‘Who Pays?’ question remain needed. With the Government expected to publish both its Net Zero Strategy and Heat and Buildings strategy soon, greater detail on that may be soon forthcoming. That is likely to provoke debate about the direction of policy and open new fronts for businesses to make their case about how the net zero transition should be delivered.

At-risk suppliers have put the energy supply industry at risk

Since the beginning of August 2021, the UK has experienced a record increase in gas prices, which has grown into a retail energy crisis that has already caused ten suppliers to exit the market this year. This crisis is the product of several factors, which the UK Government will seek to remedy in the short term and avoid in the long term. This means regulatory reforms are almost inevitable. Once the crisis is over and government turns to reforming the UK’s retail energy market, businesses that operate within it must actively engage with policymakers and regulators to ensure their voices are heard.

COP26 Update: New Energy Minister

With less than 50 days until the COP26 Summit, Brevia will be tracking the latest milestones in the UK’s preparations for the upcoming climate conference. This week the Prime Minister carried out an extensive reshuffle of his ministerial team, including a shake up at BEIS, with Greg Hands MP becoming the new Energy Minister. Other notable highlights this week include the publication of the funding details for the upcoming Contracts for Difference (CfD) Round 4 auction.
