Supply-Demand Balance – Winter 2007/08

Andrew Ryan, National Grid 19 June 2007

Describes the Winter Consultation Report covering gas and electricity and their key interactions, using a set of assumptions and scenarios to highlight what could happen over the winter (based upon views from within the energy industry). For gas, consideration is given to: non-storage supplies; the capacity of import routes and storage options; gas prices; balance in terms of peak demand (per day and during a cold week and month); the demand-supply balance for a 1 in 50 winter; and what this may mean for demand turndown requirements. This is compared alongside assumptions for electricity supply and demand; highlighting both short term and long terms issues that need to be considered to balance them.
