With large solar arrays and wind farms being proposed to connect to transmission and sub-transmission systems, are utility companies sufficiently prepared to handle the challenge of integrating these large intermittent resources? The industry now must decide whether transmission reliability factors — most notably dynamic voltage support and system frequency management — need to be resolved by renewable generators, or whether they should become a cost of doing business for transmission providers and reliability coordinators.

(June 2011) Duke and ATC team up to build transmission lines; AEP installs bioreactor to control selenium emissions; NextEra buys 100 MW of wind from Google; Ocean Power Technologies awards contracts for wave power array; Kansas City picks Elster; BC Hydro picks Itron; plus contracts and developments involving Tres Amigas, Ioxus, Opower and others.

Exelon to buy Constellation Energy, Williams Partners buys interest in Gulfstream interstate gas pipeline system, Macquarie Energy enters purchase agreement for Oak Solar project, and others.

All things being equal, momentous events like the Fukushima nuclear disaster and the Arab spring would bring fundamental changes in U.S. energy policy. But things aren’t equal, and they never will be under America’s democratic and capitalistic process. Frustrating? Maybe, but it’s the only way to ensure our decisions are based on sound economic and environmental principles.

FERC’s new rule on compensation for demand resources tips the market balance toward negawatts. Arguably the commission’s economic analysis is flawed, and the rule represents a covert policy decision that stretches federal authority. Nevertheless, economic benefits will result if DR programs are well implemented to avoid gaming the system and distorting the market.

Despite the variable nature of the resource, wind can be managed so that it will not impair the reliability of a utility system. The Federal Energy Regulatory Commission proposed a rule that would require changes to the way transmission service is scheduled, which would enhance the ability of balancing authorities to integrate wind.

New York has developed new market mechanisms intended to effectively incorporate large amounts of renewable energy in the future — up to six times the current levels of intermittent energy without impacting system reliability. New York ISO executive Rana Mukerji explains how the market will drive new investment in renewable energy in the state.
