(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.
Evaluating the impact of dynamic pricing.
Are residential time-of-use prices only effective for middle class households, or do low-income customers benefit too—as authors Lisa Wood and Ahmad Faruqui asserted in their October 2010 article? Data from pilot programs show that low-income customers exhibit a reduced ability to benefit from dynamic pricing. Demand response programs should accommodate the realities of low-income customers’ consumption patterns.
Solar projects are becoming hot investments.
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.
Combined efforts bring mutual benefit.
Regardless of what drives the action — state regulation, federal policy, economic reality — collaboration between utilities and the solar industry is now becoming prevalent. Expanding definitions of utility solar business models represent a significant potential for solar market growth, and provide paths for others to follow.

Bill Clinton and other dignitaries help Duke, Cisco and Charlotte, N.C., launch commercial efficiency initiative; AEP signs 20-year MOU to buy solar output from New Harvest plant; Wartsila expands gas-fired generator in Turkey; U.S. DOE awards geothermal RD&D grants; GE acquires Dresser for $3 billion, and also acquires Calnetix industrial cogen technology; SunEdison sells 70 MW Rovigo PV plant; Ford Motor Co.
Correcting misconceptions about load-management programs.
Do low-income customers respond to dynamic rates? The answer is yes, and in fact such customers can benefit from dynamic pricing without shifting loads”contrary to conventional wisdom. A study co-authored by the Edison Foundation’s Institute for Electric Efficiency and the Brattle Group shows that restricting access to dynamic rates might actually be harmful to most low-income customers.

Manufacturers scale up for utility applications.
Photovoltaics technology is emerging as a generation alternative—both for centralized and distributed facilities. Solar industry executives say their companies are overcoming obstacles to large-scale implementation. With advances in design and manufacturing, the future looks bright for utility-scale solar power.
The changing architecture of demand response in America.
Pilot projects are demonstrating the potential of smart metering and smart rates to make the most of supply and demand resources. But as empirical studies show, not all pricing designs are equally suited to every region.
