Delivering Renewable Energy Resources Mary Ellen Paravalos Vice President, Transmission Regulation and Commercial National Grid
US Electricity transmission National Grid - Northeast Transmission System • 14,000 miles of electricity transmission and over 500 substations • Delivering a transmission investment plan in excess of $3BN over the next 5 years • New “Work Delivery Model” will ensure that we can deliver the transmission projects at the lowest cost over the long term

Delivering Renewable Resources for New England • We have many resources available to us for development • Onshore and offshore wind • Interconnections to neighboring regions • Local distributed resources • We should understand the costs …. • Additional operating reserves, storage • Additional transmission capacity • Enhancements to grid control and smartgrid infrastructure • ….and the Benefits • Reduction on dependence of fossil fuels (particularly natural gas) • Transmission capacity will increase reliability and ability to withstand system disturbances • Smartgrid investments will bring increased customer management of energy costs, efficient utilization of infrastructure, reduced impacts on our planet
What do we need to move forward? • Changes to regional planning process • Inputs on renewable resources we should be planning for • Planning Criteria – deliverability, operability, assumptions (fossil fuel retirements) • Longterm Power Purchase Agreements will require regulatory assurances • Transmission cost allocation will become more clear as New England’s Blueprint is formed • Broad allocation for many transmission investments may make sense, as the benefits are broadly spread
