Scott Waldman is reporting at Politico New York the state's independent grid operator is concerned the Cuomo administration's primary method of achieving its goal of doubling the state's renewable energy could prove costly for consumers. The developing Clean Energy Standard would require that New York power at least half its electric grid with renewable energy by 2030. This would lead to an expansion of various renewable sources of energy including wind, solar and hydropower. Under the current proposal, this expansion will be funded by approximately $5 billion collected from monthly utility bills. These so-called purchase-power agreements would unnecessarily put consumers at risk, New York Independent System Operator officials wrote in comments recently submitted to the Public Service Commission. They called the plan a risky strategy that could lead to higher costs for consumers and other problems on the grid. Grid operator officials also recommended the state rely on competitive markets to drive renewable energy growth rather than create incentives that interfere with the open market.
