The main headlines include:
Following last year’s publication, we set out our own ‘Five Steps to FES success’ which are ALL still relevant 12 months on!
Need for National Grid to set out detailed requirements and procurement plans across Balancing and Ancillary Services.
A clear plan for the integration of DNO-led flexibility with National Grid.
Need for regulations to support co-location of generation and storage.
Ease of participation for small low carbon assets. Need for interoperability standards to drive participation.
Clarity over network charges, clear renewable subsidies, and the direction of travel for market structure.
We are pleased to see an increased focus on Flexibility in this year’s publication. Digitalisation remains at the heart of unlocking flexibility services from low voltage connected generation. This will become even more important as we see the electrification of cars from 2030 and the need for increased Demand Side Response. In May, we saw the launch of the Government’s new Energy Digitalisation Taskforce which has the big task of delivering a digital roadmap to support industry change. This will need to be supported by the prompt removal of regulatory barriers.
Under the ‘Leading the Way’ scenario, there is a requirement of 12 GW of battery storage by 2030 and 28GW by 2050, while currently there is only 1 GW connected to the grid. This highlights the massive opportunity within the battery market right now. Whilst we are seeing strong returns for batteries in the new frequency product, Dynamic Containment, this has nearly reached its capacity and does not provide the long-term investment signal for batteries. Instead, this will need to come from appropriate wholesale market price signals and the ability to ‘stack’ revenue streams. We have seen some encouraging trials using batteries for services such as Restoration (i.e., after a black out) and to provide Reactive power. We will need these to materialise into real world markets and products.
In April, we saw National Grid publish their Market Roadmap to 2025 which provided insight to their future ambitions. This was helpful but needs to go further to include an estimate of the volume of products required up to 2025 and beyond. National Grid is also running a Net Zero Market Reform programme looking at the challenges in the electricity market and the case for change to meet net zero while OFGEM has its ‘Full Chain Flexibility’ programme. The challenge for the Government and Regulators is bringing all innovative initiatives together to provide clear market signals for owners, optimisers, and users of battery storage and renewable generation. This is no small challenge, and we cannot afford any delay.
The FES is a great focal point to highlight the enormous changes required and challenges to delivering net zero. We now need clarity over the stages for delivery with appropriate milestones and checkpoints to ensure success.
