The power grid has been slow to embrace renewable energy sources. In order to allow renewable energy sources to evolve into a solution rather than a headache, new tools and processes will need to be developed to forecast and control renewable production capabilities.

Utilities are using automation and back-office systems to improve their performance on outage management and service restoration. The next generation of smart-grid technologies promises a revolution in self-healing systems. But first the industry must gain confidence in the technology—and the business case for investment.

The IEEE P2030 Work Group is developing standards to encourage seamless deployment, integration and operation of energy, information and communication technologies across the smart grid. Utility input and engagement is needed to produce workable standards.

Power delivery efficiency gains constitute a valuable utility asset that can offset or defer new generation and T&D investments. Enabling technologies, utility demonstration projects and supporting regulatory frameworks are needed to validate potential savings.

In light of all the excitement created by smart-grid regulatory initiatives and stimulus funding, three clever tech startups have come forward with proposals for novel grid projects. In California, Western Grid Development proposes to install energy storage devices ranging in size from 10 to 50 MW at various discrete and strategic locations in PG&E’s service territory where the California ISO has identified reliability problems. Second, a company called Primary Power proposes to deploy a total of four advanced, 500-MVAR static VAR compensators (SVC) at three separate locations within the PJM footprint. Third, in Clovis, N.M., Tres Amigas plans to allow power producers to move market-relevant quantities of electric power and energy between and among the nation’s three asynchronous transmission grids: ERCOT and the Eastern and Western Interconnections.

Regulatory policies are evolving to make demand response and smart-grid planning a reality across the country. Cooperation between federal and state lawmakers will allow local flexibility within a uniform national framework.

The U.S. power market consistently has displayed cyclical characteristics of boom and bust over the last two decades. Today’s market environment has been directly and significantly impacted by the recent economic recession. Decreases in load growth, declining commodity prices, and lack of accessible financing have caused challenges for the industry.

With the administration and Democratic lawmakers in Congress pushing to enact greenhouse-gas (GHG) regulation, nuclear power has taken center stage as both a clean technology solution and a political bargaining chip. Consequently, the industry’s hopes for new construction projects have brightened considerably. Whether this policy momentum can usher in a sustainable nuclear renaissance, however, remains questionable at best.

Like other California electric utilities, San Francisco-based Pacific Gas & Electric (PG&E) has been scrambling to meet the state’s renewable portfolio standard (RPS), which requires suppliers to obtain at least 20 percent of their power from renewable energy sources by 2010. Though the RPS includes a variety of technologies, renewables developers are choosing utility-scale solar power more than any other resource, says Hal La Flash, PG&E’s director of emerging clean technologies.

Utilities traditionally have met renewable portfolio standards with power purchases from IPPs. But new approaches are allowing utilities to build their rate bases with investments in solar generation.
