Transmission limits hamper renewable energy plans
State and regional regulators acknowledge the hurdles - especially in northern New Hampshire - but don't have ready solutions. A bill before the New Hampshire Senate would have the state be ready to act if no regional solution is forthcoming. ISO New England, which manages power for the region, is considering changing rules so more of the costs of transmission upgrades could be shared regionally. But as things stand now, backers of projects generally must pay for upgrades needed to connect them to the system. "None of this is a real speedy process," acknowledges Michael Harrington, senior regional policy adviser for the state Public Utilities Commission.
