Achieving aggressive renewable energy goals will require building thousands of miles of new transmission lines, and these so-called “green-power superhighways” could bring major new sources of low-cost electricity into the market. But will those sources be renewables? Analysts Roger Bezdek and Robert Wendling argue that with new access to distant wholesale markets, coal-fired generation would become more competitive than ever.

Where wind integration has been most successful, state authorities developed and adopted basic transmission planning and cost allocation principles before FERC issued Order 1000. Experiences in Texas, California, and Hawaii demonstrate what it takes to overcome permitting and cost allocation barriers—namely, a coherent policy framework and close coordination among stakeholders.

New technologies—and new expectations—require taking a fresh look at the institutions and practices that have provided reliable electricity for the past century. Collective action is needed to define the key attributes of a future grid and then to take the more difficult next step—adapting our processes and institutions to align with that future vision. A thoughtful approach will allow America to capture the potential value that’s offered by sweeping changes in technologies and policies.

(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 the abandonment of a nationwide energy policy by the previous Congress, states continue leading carbon mitigation efforts. Indeed, existing state policies and renewable portfolio standards (RPS) are already having a significant impact on the U.S. generation portfolio. FERC now proposes to weigh state policy as a consideration in transmission filings. Should state policies guide federal action? Will they suffice to reduce carbon emissions?

The goal of implementing a distribution management system (DMS) is to upgrade isolated, hands-on grid management processes into an interconnected and automated platform. This technology is transforming the way utilities operate distribution networks, and setting the industry on a path toward seamless integration of distributed resources—both supply and demand.

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.

FERC has proposed that wholesale energy markets should subsidize load reductions with full LMP (locational marginal price), without deducting the customers’ retail savings. Such a policy could distort the market, and other solutions might achieve the same objectives more efficiently.

Demand-response technologies are quickly becoming more sophisticated, and markets are treating demand as a resource. But realizing the true potential of DR requires utilities to apply today’s technology solutions and program structures—and to base their strategies on actual customer behavior and preferences—rather than yesterday’s outdated assumptions about centralized load control.

Ultracapacitors and batteries work together to solve power quality problems.
