SONI074 DS3 System Services – Volume Capped – Gate 14

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%.
