§ Mr. TynanTo ask the Secretary of State for Trade and Industry on what basis her Department includes(a) generators subject to transmission constraints and (b) inherently intermittent generators in aggregated totals of generation capacity when comparing levels of installed generation capacity against possible levels of electricity demand. [178351]
§ Mr. TimmsNational Grid Transco (NGT) reports the level of installed generating capacity relative to forecast levels of electricity peak demand in its annual "Seven Year Statement" (SYS) and the associated quarterly Updates.
NGT do not currently differentiate the capacity of intermittent generators directly connected to the system from other forms of installed capacity. The registered capacity of any transmission-constrained generator is adjusted to the limit of the constraint in question.
