Flexible grid management solutions in UK and Switzerland
This document discusses flexible grid management solutions in the UK and Switzerland. It provides an overview of electricity production, consumption, imports and exports in 2013 for both countries. It then discusses the UK's electricity distribution network and top disruptive events on the grid in 2013. Key differences between electricity, capacity and balancing markets in the UK are explained. Flexitricity's smart grid demand response program and potential revenues from the UK's upcoming Capacity Market are also summarized. The document concludes with an overview of Xamax's existing load management systems in Switzerland and their potential to provide secondary control power services.

Price Control Reviews and Guaranteed Standards - All 14 DNOs submit detailed business plans on the same cycle (currently 5 years transitioning to 8 years). - Ofgem evaluates the DNOs plans and revenue requests against each other and against other efficiency benchmarks. - The outcome of the price control review is a set of allowed revenues (not rates) on a forward looking basis. Supply restoration incentives: £ 54 per household if outage is longer than 18 hours. (additional £ 27 for each 12 hours) £ 50 for 4 or more cuts each longer than 3 hours in a 12 month period.
