This week we look at: the admittance of up to 300MW of aggregated assets into the Balancing Mechanism, new arrangements to restore
Up to 300MW of assets to be admitted into the Balancing Mechanism
The
The ESO states that the changes will widen consumer participation in flexibility, by opening the BM up to small scale assets such as EV chargers and electric heating systems. This will help the ESO to balance the electricity system in real time.
These aggregated assets will be subject to relaxed requirements for operational metering to encourage participation. Current metering rules require assets in the BM to deliver readings every second with a permitted margin of error of +/-1%, which has discouraged smaller entrants. After conducting a trial on allowing small scale assets in
The ESO has commissioned an independent report to determine the exact changes it should make to the operational metering requirements to encourage these 1MW assets to participate in the BM over the long term.
Ofgem approves arrangements for restoring power grid
Ofgem has approved a set of code modifications to implement the Electricity System Restoration Standard (ESRS). The ESRS was announced by the government in a policy statement in
Ofgem has approved the following modifications to energy industry codes to implement the ESRS:
-
The DCRP/MP/22/02 modification amends the Distribution Code to set out requirements including the introduction of the "bottom-up" restoration method. This method approaches restoration from the distribution level after a blackout, instead of at the transmission level.
- The GC0156 modification sets out changes to the Grid Code related to the controllability and availability of generation and network assets. Changes include ensuring that generators and network substations can continue operating for at least 72 hours after the loss of external electricity supplies.
- The GSR032 modification alters the National Electricity Transmission System Security and Quality of Supply Standards. It introduces design requirements for transmission systems to facilitate participation in restoration plans, to permit power stations to synchronise with power islands, and to prevent system collapse during restoration.
- The CM089 and CM091 modifications align the System Operator Transmission Owner Code with the Grid Code and require transmission owners to consider the impact of proposed outages on the ESRS.
These modifications are due to come into effect on

Government announces measures for EV chargepoint installations
The government has announced a suite of new measures to support the installation of new electric vehicle (EV) chargepoints across the
Under the announcement, the
As part of the measures, the government has allocated the first grants from the Ł381 million Local
The DfT has also launched a fresh grant for state-funded schools and education institutions to procure and install chargepoints on-site, up to the amount of either Ł1,500 or Ł2,500 per socket depending on the area and type of installation, to a maximum of 40 installations per site.
