Winter Demand Reduction Incentives
An incentive to reduce load at peak
System security
Previously most Customers participated in WDRI
Many large Customers moved to Independent Suppliers
WPMP introduced, but not successful

Introduction of WPDRS
ESBNG introduced WPDRS in 2003/04
Ensured all Customers had access to incentive
Open to:
– Customers in the Eligible Market
– Supplied by Independent Supplier
– Appropriate metering etc. also required
NATIONAL GRID
How does WPDRS work?
Reliable load reductions and reduced energy
consumption rewarded
– Rebate charged if Customer is unreliable
Customers reduce consumption or bring on
generation to replace demand from system
Incentives offered for Customers with generators who
can export load
Suppliers receive administration fee
