America’s electric utilities understand their central role in taking efficiency and conservation to the next level. Accordingly, the industry has nearly doubled its spending on efficiency measures in the past few years. But encouraging customers to save energy won’t be enough to keep pace with the electricity demands of a growing digital economy. The country’s efficiency efforts will be most effective as part of a clean energy portfolio strategy.

Nanomanufacturing technology works on the concept that materials reduced to the nano scale can show different and improved properties compared to those exhibited on a macroscale. For nanotech giant, Applied Materials, the ability to apply thin films at the atomic level is the answer to making solar energy more cost effective. Michael Splinter, chairman, CEO and president of Applied Materials, spoke with Fortnightly about nanotech developments for utility-scale solar.

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.

FERC’s proposed penalty guidelines provide the opportunity for improved regulation. More practical and consistent characteristics for determining penalty fine ranges will increase penalty predictability for industry violations of federal regulations—and will make FERC’s enforcement more fair and transparent.

California’s new feed-in tariff (FIT) is creating a burgeoning market for green energy investments, but the policy has sparked a fierce battle over state authority to dictate wholesale power transactions. A federal case will determine whether the 1978 Public Utility Regulatory Policies Act pre-empts states from requiring purchases that exceed utilities’ avoided cost.

Investor-owned utility executives have long understood the benefits of prepaid metering, but technical and regulatory roadblocks have prevented wide-scale implementation. Now, however, two IOUs—Arizona Public Service and DTE—are planning prepaid metering programs that could be offered to all customers. Smart metering technology might pave the way for prepaid to become a standard service.

Visitors to Waynesboro in northeast Georgia might be surprised at local residents’ opinions about two new nuclear energy plants planned for that site; namely, they’re giving the reactors a warm welcome.

Is customer engagement more about damage control, or helping customers understand their options?

Calpine buys 5 GW of generating capacity from Pepco Holdings for $1.65 billion; Xcel buys two Calpine plants in Denver for $739 million; Asset acquisitions announced in April by Constellation, Kaukauna Utilities and others totaling $3 billion.
