Preparing the grid for large-scale renewables.
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.
Green energy mandates might overburden gas pipelines.
By Diane A. Rigos, Boris L. Shapiro and Richard L. Levitan
Market rules could evolve to compensate gas suppliers for pressurizing pipelines when needed on short notice. Enhanced ancillary services will require innovative strategies using line pack in interstate pipelines and stepped up communication among gas and electric market participants to preserve reliability objectives in gas and electric markets.
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.
(October 2010) AWEA’s manager of transmission policy refutes author Robert Blohm’s assertion that renewable power exacerbates America’s growing problems with frequency response.
Transmission expansion costs are spread unevenly, driving a wedge between utilities and regions.
Back in June, the Bismarck Tribune ran an interview with North Dakota Public Service Commissioner Tony Clark that showed just how difficult it is to build national consensus for renewable energy.
How much efficiency do ratepayers need—and utilities want?
When the applause dies down, the smart grid may turn out to be its own worst enemy. The California Independent System Operator (CAISO) explained this irony in comments it filed in May, after the FERC asked the industry for policy ideas on the smart grid.
The search for the ultimate wind forecasting model got a boost at the end of 2008 when DOE’s Argonne National Laboratory began collaborating with a Portuguese research institute, INESC Porto, to develop a new platform for making such predictions.
Subsidies might not be the best solution for interconnecting renewables.
Supporters of renewable energy are seeking to socialize the cost of a new interstate highway system for transporting green power. But utilities and transmission owners will build or finance new transmission systems to serve economic demands. Policy makers shouldn’t pre-ordain the direction of industry progress.
How a move to bring power markets to the Great Plains has uncovered a crisis in grid planning.
They call the United States the “Saudi Arabia of Wind.” That’s due in large part to the huge potential of the Great Plains. But there’s a hole in the metaphor. Wind power development in some parts of the prairie is falling short of expectations.
Taming the Wind is a pleasure to read. The article captures just about perfectly the value of forecasting in cost-effectively and reliably integrating wind power, of balancing in large markets, of geographical spread, and more. It also looks at what the future could hold.
