Only as a last resort (Power Emergency) to avoid the risk of a complete blackout does ERCOT ask utilities to reduce demand by dropping load through rotating outages.
If the situation does not improve, ERCOT will first drop load resources (a market-based demand response program) and other resources under contract to be interrupted during an emergency.
Coventry City Council and Warwickshire County Council websites had full lists of closed schools, but due to heavy demand, they were slower than usual to load at times.
The Windows Mobile 6 Standard software load is fairly typical, albeit mildly Sprint-ified with a yellow theme and shortcuts to access On Demand, Sprint TV, and the like.
