Update post National Grid ESO event

 

National Grid ESO commit to new system launch on 12 December 2023 as well as a
detailed timeline of further system improvements.

 

National Grid Electricity System Operator (ESO) hosted an event on 16 October
called 'Enhancing Energy Storage' to provide clarity on the system improvement
plans in the Balancing Mechanism (BM), to better utilise the flexibility
offered by Battery Energy Storage Systems (BESS).

 

The key challenge experienced by GRID and the wider BESS sector to date, has
been the lack of utilisation of BESS in the Balancing Mechanism, which has
significantly limited revenues. ESO has communicated the following important
positive steps to remove these limitations to a large degree by the end of
2023, with further improvements due in 2024:

·      Launch of the ESO's new IT system, Open Balancing Platform (OBP)
with a new algorithm, the Bulk Dispatch Operator (BDO), is now set for 12
December 2023 (previously 15 December 2023).

·      The BDO will automate the aggregation of multiple BESS to enable
their use in the Balancing Mechanism. Of the ESO initiatives, this is expected
to have the greatest impact on the BESS utilisation.

·      Fast Dispatch will go live in Spring 2024 to allow the use of
BESS for more rapid, marginal actions.

·      The 15-minute input parameter (limiting BESS actions to 15
minutes) is expected to be made flexible by the end of 2024. ESO will run
trials following the launch of OBP and BDO in December 2023 to drive further
usage of storage assets for reserve requirements in the near term.

·      The launch of Balancing Reserve (March 2024) and Quick Reserve
(Summer 2024) services will provide further system flexibility for the ESO and
offer BESS additional revenue opportunities. This incremental revenue can be
combined with existing services and the BM at any one time.

 

Ben Guest, Fund Manager of Gresham House Energy Storage Fund plc and Managing
Director of Gresham House New Energy, said:

 

"We are grateful to ESO for its commitments to improve utilisation of
batteries and pleased to see the release of their new system brought forward.
We continue to support and engage with ESO on the implementation of their
workflow.

 

As renewable generation increases, ESO needs batteries to ensure its
flexibility requirements are met, as well as to meet its publicly stated goal
of being able to operate a carbon-free grid by 2025. We are encouraged that
ESO's prime incentive is to make these system improvements to meet its own
objectives, and not simply to accommodate BESS operators.

 

Separately, we are pleased to see ESO progress also being made to unlock grid
connection bottlenecks. These were discussed at ESO's separate event in London
covering the prioritisation and acceleration of grid connection dates for new
BESS projects, following the recent Government announcement(1)."

Definition of utility-scale battery energy storage systems (BESS)

 

Utility-scale battery energy storage systems (BESS) are the enabling
infrastructure that will support the continued growth of renewable energy
sources such as wind and solar, essential to the UK's stated target to reduce
carbon emissions. They store excess energy generated by renewable energy
sources and then release that stored energy back into the grid during peak
hours when there is increased demand.
