Fixed contracts recommendation

In 2019, we published a recommendation paper alongside EirGrid. It focused on the contractual arrangements for the DS3 system services fixed contracts process. This is also known as volume capped.

It provides specific contractual arrangements for new providers of particular system services with a very high level of availability. The terms and conditions differ from the regulated tariff arrangements.
