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.

(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.

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.

Some of the key policy mechanisms and market factors that triggered the boom in renewable energy development have weakened in the face of one of the most severe economic downturns in modern history. In some ways, though, the renewables sector is richer and more dynamic today than when the boom began. A shakeout might be coming among renewable power players, and those that survive will strengthen their capabilities, hone their strategies, and take advantage of industry consolidation to build scale.

(May 2011) Florida Power & Light unveils hybrid solar power plant; SECO selects Sensus for smart grid technology; Lockheed to implement Con Edison energy efficiency programs; Elster partners with SAIC to deliver comprehensive smart grid solutions; Columbia Power Technologies deploys wavepower prototype system; plus contracts and announcements from GE, Siemens, Verizon Wireless, DT, Xcel, Tenaska Solar and others.

(April 2011) GE Hitachi and Lockheed Martin team up on nuclear reactor controls; Elster wins metering contract in New Hampshire; Xcel hires Bechtel for nuclear services in Minnesota; Mitsubishi builds transformer HQ in Memphis; Northeast Utilities taps Siemens for transmission projects; Iberdrola sells wind output to FirstEnergy; Consumers and DTE invest $400 million to upgrade pumped storage facility; plus contracts and announcements from Alstom, URS, Areva, groSolar, Pattern Energy, S&C Electric and others.

Are the Feds at war with green power development? You might have thought so, if you had sat through the conference held March 15, 2011, at the Federal Energy Regulatory Commission, where the consensus seemed to be that FERC’s policy of granting open-access rights on electric transmission lines is problematic for green power projects. In short, when wind and solar developers choose to build their own local tie lines to link their projects to the larger grid, FERC policy forces them to make extra line capacity available to rival developers. That requirement doomed the novel Wind Spirit Project, and continues to complicate the job of project financing.

(March 2011) TVA and EPRI demonstrate solar-assisted EV charging station; Ford unveils the all-electric Focus; Central Maine Power awards substation contracts; ERCOT deploys ABB software in nodal market; FirstSolar starts up PV plant for Southern Company and Ted Turner; plus contracts and announcements involving Open Systems International, Verizon, Suntech Power, Alcatel-Lucent, Siemens, Cisco, Elster, Sensus, Silver Spring Networks and others.

With recent scale-up in both photovoltaic and concentrated thermal facilities, solar energy is nearing cost parity with wind and even some fossil generation sources. And with development models evolving to help companies manage technology risks, solar power has become an attractive investment opportunity—not just for tax-equity players, but also for utilities.
