Battery maker Invinity Energy Systems has been awarded £11 million ($13.7 million) by the British government to build the UK''s largest-ever grid-scale battery storage.
The grid-scale battery storage project will feature Invinity''s Vanadium Flow Battery technology, which provides long-duration, nondegrading energy storage and is ideal for the management of renewable energy systems. Invinity asserts that its battery technology will last for more than 25 years and is almost completely recyclable.
The battery will be integrated with the existing power infrastructure and will provide crucial support to the National Grid during times of peak demand. The battery is expected to go live in 2025, and it will be the longest-duration battery asset to be connected to the UK grid.
This investment is a clear signal from the Department for Energy Security and Net Zerothat long duration energy storage [LDES] will play a vital role in delivering a secure and affordable UK energy transition.
The UK is already an LDES pioneer,with market conditions that provide a positive environment to supportthese new technologies to reach maturity at scale andpace, anddeliver real impact this decade.
This investment could prove to be a pivotal moment for the UK’s energy grid, and we hope to see it have global ramifications, to stimulate more of this type of investment into LDES around the world.
The UK is aiming to fully decarbonize the country''s electricity by 2035. Since 2021, the country has spent more than £390 million turning off its wind farms to manage grid curtailment during times of oversupply and used gas power plants to fill in supply shortages. So grid-scale battery storage provides a solution to these challenges.

The UK is undoubtedly one of the hottest global markets for battery storage today and a considerable pipeline of projects exists. But which projects will likely get built, and when? Thein-house analysis and research team at Solar Media Market Research answers these questions and many more. AnalystMollie McCorkindale from the team, which is part of Energy-Storage.news' publisher Solar Media, explains some of the methodologies to filter out the top 10 projects in development in the UK.
The pipeline of utility-scale and large commercial segments for battery storage in the UK is continually increasing, with a pipeline of over 16GW of projects with the potential for deployment over the next few years.
This article summarises the output from new analysis of the UK pipeline, explaining how to identify the top ten battery storage projects that are most likely to be completed during 2021. All data is taken from ourUK Battery Storage Project Database report.
Currently, the total operational capacity for battery storage in the UK is 1.3GW with 130MW having been commissioned already this year. The graphic below shows a flow diagram that summarises the remaining 2021 site prospects, within the total pipeline of 686 sites.
The analysis starts with the total pipeline of 16.5GW across 686 sites and filters out the sites smaller than 5MW. These smaller sites are usually co-located, and the timescale for deployment depends often on co-located site criteria for completion. After these small sites are removed, the pipeline is at 16.2GW across 546 sites.
Next, by removing sites that are only at the pre-application planning stage, this takes the pipeline to 10.6GW (373 sites), which have reached the full application stage. The pre-application stage refers to screening/scoping (or pre-application planning in general).
This segments out now all projects at full application stage: the next step is to remove sites that have not yet had planning approval. The average timeframe for projects – from application being approved to final commissioning – is normally about 18 months, which suggests it is very unlikely for any unapproved applications to be completed this year. Applying this filter takes the pipeline to 9.2GW across 325 sites.
These 325 sites are then split into two segments (short-term prospects and mid/long-term prospects), depending if any progress has been undertaken since planning approval. Projects in the mid/long-term prospects segment generally fall into the ‘no-progress’ category (such as a final developer coming on board, appointing an EPC or battery supplier or announcing the start of construction).
By removing the mid/long-term prospects, the pipeline for short-term prospects is now 3.2GW made up from 100 sites. These sites have the potential of being deployed within the next 12-18 months. The graphic below now shows these short-term prospects by project size category.
Generally, the size of the site depends on the type of project being constructed; large capacity sites are usually from stand-alone projects, whereas co-located sites vary in size but are usually much smaller. 73% of the planned capacity in the short-term prospects is from large capacity (>30MW) projects, implying most of these are stand-alone.
A handful of these sites now have a final developer in place, and an appointed EPC and battery supplier, suggesting completion in the near future. This leaves the pipeline for 2021 site prospects at 298MW across 10 sites. Adding this capacity to the 130MW of operational capacity so far this year means 2021 could exceed 400MW, broadly in line with our forecast of new large-scale storage capacity coming online in the UK.
So far, battery storage sites have been installed throughout all regions of the UK, with the South East region having the largest operational capacity and an even larger proportion of the total planned capacity; therefore, it is not surprising to see the South East region dominating the capacity in the 2021 site prospects.
Of course, it is not guaranteed that all ten sites will be completed by the end of this year, as some may slip, or deployment may be slowed due to construction delays. If so, these sites will likely carry over and be completed during the first half of 2022.
All of these projects are gathered together, updated daily and released every month in theUK Battery Storage Project Database report. If you would like to learn more about accessing this information, please contact us via the report landing pagehere.
