Ofgem has agreed a number of changes to the Capacity Market ahead of a major review of the policy later this year.
The regulator will take forward most of the proposals outlined in Spring.
The changes will allow capacity market units that had opted out as non-operational for that delivery year to now bid in to the T-1 auction.
More providers will also be able to participate in secondary market trading, including those that originally failed to prequalify and recently commissioned providers, said Ofgem.
The regulator said DSR testing would also be simplified. Specifically, where a demand-side response capacity market unit alters its metering configuration, a new DSR test will no longer be required for the same delivery year.
