SONI074 DS3 System Services – Volume Capped – Gate 14

Tender description

Following review by the Regulatory Authorities of the TSOs’ Report on Ensuring a Secure, Reliable and Efficient Power System in July 2011 the TSOs were requested by the SEM Committee to put in place a programme of work to solve the challenges associated with increased levels of penetration of variable non-synchronous renewable generation. In response the TSOs formally commenced the DS3 Programme in September 2011. The overall aim of the DS3 Programme is to put in place the required changes to system policies, system tools and system performance to meet the challenges of operating the electricity system in a secure manner while achieving the 2020 renewable electricity targets. A key aspect of this operational challenge is the increase of System Non- Synchronous Penetration (SNSP) from the 2011 limit of 50% to 75%. ## Contract award Title: POR L1NI Primary Operating Reserve Lots: - Lot 1: POR L1NI - Primary Operating Reserve ## Contract award Title: SOR L2NI Secondary Operating Reserve Lots: - Lot 2: SOR L2NI - Secondary Operating Reserve ## Contract award Title: TOR1 L3NI Tertiary 1 Operating Reserve Lots: - Lot 3: TOR1 L3NI - Tertiary 1 Operating Reserve ## Contract award Title: TOR2 L4NI Tertiary 2 Operating Reserve Lots: - Lot 4: TOR2 L4NI - Tertiary 2 Operating Reserve ## Contract award Title: RRD L5NI Replacement Reserve (De-Synchronised) Lots: - Lot 5: RRD L5NI - Replacement Reserve (De-Synchronised) ## Contract award Title: RRS L6NI Replacement Reserve (Synchronised) Lots: - Lot 6: RRS L6NI - Replacement Reserve (Synchronised) ## Contract award Title: RM1 L9NI Ramping Margin 1 Hour Lots: - Lot 9: RM1 L9NI - Ramping Margin 1 Hour ## Contract award Title: RM3 L10NI Ramping Margin 3 Hour Lots: - Lot 10: RM3 L10NI - Ramping Margin 3 Hour ## Contract award Title: FFR L12NI Fast Frequency Response Lots: - Lot 12: FFR L12NI - Fast Frequency Response ## Contract award Lots: - Lot 7: SSRP L7NI - Steady State Reactive Power ## Contract award Lots: - Lot 8: SIR L8NI - Synchronous Inertial Respons ## Contract award Lots: - Lot 11: RM8 L11NI - Ramping Margin 8 Hour
