Renewable portfolio standards and other green energy rules put a price on environmental benefits. Calculating this price can help clarify the social value of GHG reductions.

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.

Regulators across the country are relying on conservation-potential assessments to guide their policy decisions. Models based on macroeconomic analysis, end-use forecasting and accounting measurements provide different ways to assess the achievability of conservation and efficiency goals.

Lockheed Martin teams with Tendril; Pattern Energy 101 MW wind plant starts operating; Alstom to supply steam equipment to GWF plant; Siemens wins government efficiency contract; GE Jenbacher introduces high-efficiency gas engine; OpenADR Alliance forms; Better Place gets into San Francisco taxis; EnerNOC enters TransAmerica Pyramid; and more.

Alstom introduces a new 3-MW wind turbine, one of the world’s most powerful for onshore installations; Solyndra reports its larges-ever rooftop installation of cylindrical photovoltaic (PV) systems — a 704-kW project in New Jersey; Plug Power reports that its GenDrive fuel cell units will power Walmart Canada’s fleet of electric lift trucks at a Alberta distribution center.

America’s electric utilities understand their central role in taking efficiency and conservation to the next level. Accordingly, the industry has nearly doubled its spending on efficiency measures in the past few years. But encouraging customers to save energy won’t be enough to keep pace with the electricity demands of a growing digital economy. The country’s efficiency efforts will be most effective as part of a clean energy portfolio strategy.

The one-day-in-10-years criterion might have lost its usefulness in today’s energy markets. The criterion is highly conservative when used in calculating reserve margins for reliability. Can the industry continue justifying the high cost of overbuilding?

Mandatory renewable portfolio standards are becoming the norm. But after low-hanging green fruits are harvested, renewable power might get scarce. Many utilities will struggle to meet RPS requirements until lawmakers create stable federal policies and a national market for green credits.

Utility commissions are responding to their constituents by dramatically increasing emphasis on funding for energy-efficiency and demand-response programs. They believe—and expect—advanced metering infrastructure (AMI) will contribute substantially to both areas.

Natural-gas estimates from the Energy Information Administration (EIA) are supposed to be “policy neutral.” Are they? Over the past decade, EIA forecasts for NG differ substantially from actual outcomes—even though overestimations of supply capabilities could lead to underestimating the costs of carbon regulations.
