NATIONAL GRID Winter Peak Demand Reduction Scheme (WPDRS) Michael Walsh ESB National Grid Sustainable Energy Ireland – LIEN Workshop Kilkenny, 22 nd July 2004

NATIONAL GRID Presentation Overview  Winter Demand Reduction Incentives  How does WPDRS work?  Results from 2003/04  Product Development  Next Steps  Information

NATIONAL GRID 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  By 2003/03 no real incentive available to independently supplied Customers…and it showed

NATIONAL GRID 1999 – 2000 Effect on Peak

NATIONAL GRID 1999 – – 2001 Effect on Peak

NATIONAL GRID 1999 – – – 2002 Effect on Peak

NATIONAL GRID 1999 – – – – 2003 Effect on Peak

NATIONAL GRID 1999 – – – – 2003 Effect on Peak No noticeable effect on Peak in 2002/03!

NATIONAL GRID 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

NATIONAL GRID Payment Structure - summary ENERGY RELIABILITY €50/MWh Paid for reduced energy consumption Can vary day to day €160/MW Paid for remaining below committed quantity Set for the month Rebate mechanism for breach (€3200/MW) Total Available Payment: €210/MW/h = 21c / unit

NATIONAL GRID Payment examples – indicative (assuming 100% reliability) Company A Company B Company C Baseline Demand (MW) Committed Level (MW) Committed Quantity (MW) Daily Reliability Payment€96.00€320.00€3, Expected Energy Consumption (Units) Actual Energy Consumption Reduced Energy Consumption Daily Energy Payment Total Daily Payment€126.00€420.00€5, Total Winter Payment€10,332.00€34,440.00€413,280.00

NATIONAL GRID Results from 2003/04  Customers signed up  Load reduction each day  Total paid out  Effect on Peak?

NATIONAL GRID 2003/04 Results: Customers Signed-up  Level of Participation Total of 639 Customers able to take part 29% signed up Increased Customer Base for 2004/05 season 186 participating 453 non- participating

NATIONAL GRID 2003/04 Results: Monthly Peak Reduction  How much was delivered under the WPDRS in 2003/04? 82.5 MW83.0 MW84.4 MW81.3 MW Peak Reduction Delivered ~ 80 MW NovDecJanFeb Month Average MW Reductions

NATIONAL GRID 2003/04 Results – Peak down though Consumption overall up

NATIONAL GRID 2003/04 Results Summary  186 Customers  ~ 80MW load reduction each day  Total paid out : Customers: €2.4m Suppliers: €120,000  Effect on Peak…

NATIONAL GRID WPDRS Development  Results published  Consultation Process May – June 2004  Responses received from Suppliers, Customers and others  Changes to Scheme proposed

NATIONAL GRID Proposed Changes – Not finalised CHANGES HAVE NOT BEEN CONFIRMED  Key Change: Protect Energy Payment from Rebates (see example below) Still require a minimum level of performance  Other Changes: Extend Scheme into March PES Customers will be allowed to participate  More Information Optimal Committed Level to be calculated Spreadsheet examples to be published
