(April 2012) MidAmerican Energy awarded a contract to Siemens Energy to supply wind turbines for its 407-MW project expansion. American Electric Power began operating the 580-MW Dresden natural gas-fired combined-cycle power plant. Duke Energy and ChinaHuaneng Group signed a three-year agreement expanding their research cooperation to include coal and carbon capture and sequestration technologies. And others...
Technology opens customers’ homes to utility services.
Matt Dinsmore and Laurence Wong
Advanced metering infrastructure and intelligent appliances are opening the door to a new market for utility services. But in-home services are a completely different ball game. Going beyond the meter will require utilities to transform the way they engage and serve customers.
Utilities prepare for a bumpy road.
Ed May and Stephen Johnson
Electric vehicles promise major benefits for utilities, including increased electricity sales and accelerated transformation of passive energy consumers into collaborative stakeholders. But EV integration faces major challenges, from transformer overloading to the complexity of managing mobile transactions. Addressing these challenges in a collaborative way will allow the industry—and the country—to realize the benefits of a healthy market for electric transportation services.
Reviving hope for spent-fuel storage.
With Yucca Mountain declared dead, America’s nuclear power industry needs new solutions for managing spent fuel. Although the task is complicated, examples of siting success provide hope that a collaborative approach can close the nuclear fuel cycle.
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.
The entire utility-consumer relationship must be reengineered.
The business case for advanced metering infrastructure (AMI) can’t be justified alone on operational savings to the utility. But critical assumptions involving process improvements and system efficiencies depend on customer involvement. This sequel to a September 2009 article examines customer engagement strategies and techniques.
Increasing prices for materials, equipment and services are driving utility infrastructure costs into uncharted territory.
Greg Basheda and Marc Chupka
The evidence is overwhelming: After a decade of relatively stable, or even declining, construction costs, the industry is now facing a prolonged period of elevated construction price tags. What are the causes behind this trend, and how might the cost increases translate into higher rates?
What the U.S. electricity sector must do to significantly reduce CO2 emissions in coming decades.
Revis James, Richard Richels, Geoff Blanford, and Steve Gehl
The large-scale CO2 reductions envisioned to stabilize, and ultimately reverse, global atmospheric CO2 concentrations present major technical, economic, regulatory and policy challenges. Reconciling these challenges with continued growth in energy demand highlights the need for a diverse, economy-wide approach.

The process of calculating meaningful benchmarks is fraught with pitfalls.
Regulatory reporting requirements for major U.S. utilities provide a wealth of data for benchmarking studies. Both the Federal Energy Regulatory Commission (FERC) Form 1 for electric utilities and FERC Form 2 for gas utilities involve the reporting of more than 2,500 unique data points per utility per year, across diverse aspects of utility operations, maintenance, and finance.
Seven recommendations to improve TMI's nuclear plant security that have gone unheeded.
