When Électricité de France stepped in to buy Constellation Energy’s nuclear assets and help the company avoid bankruptcy, the Maryland Public Service Commission conditioned the sale on a set of ring-fencing provisions. The industry has been using such structures to protect ratepayers in complex and high-risk M&A transactions since the 1990s. The protection isn’t foolproof, however—and it can bring problematic regulatory trade-offs.

Alstom introduces a new 3-MW wind turbine, one of the world’s most powerful for onshore installations; Solyndra reports its larges-ever rooftop installation of cylindrical photovoltaic (PV) systems — a 704-kW project in New Jersey; Plug Power reports that its GenDrive fuel cell units will power Walmart Canada’s fleet of electric lift trucks at a Alberta distribution center.

CenterPoint Energy floats registered public offering of 22 million common shares; ConEd issues $700 million in senior unsecured debt in two tranches; 10-years notes; Duke Energy raises $45 million by leveraging ownership in the 14-MW Blue Wing Solar Project in Texas.

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

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.

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.

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.

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.

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.
