Reducing Lifecycle Expenditures

Total cost of ownership accounting optimizes long-term costs.

A large regional utility forfeited significant operating revenues after it replaced pulverizers at several of its coal-fired power plants. Because the replacement pulverizers were sized to operate at 100-percent capacity during operations using the coal typically procured by the utility, upgraded plants had to be derated following a change to lower BTU-rated fuel. If utility decision makers had used a total cost of ownership (TCO) framework, they could have avoided this situation.

Renewables and Carbon Markets

Allowance structures will influence project economics.

Carbon-reduction policies are being designed and implemented across the country. One common feature of these regulatory programs is a carbon cap-and-trade system—i.e., a carbon emissions market.

Green Imagineering

Perception trumps reality at Florida ‘solar city.’

Once upon a time, a real estate developer dreamed of building a planned community. The developer, Syd Kitson, envisioned a “city of tomorrow™” in southwestern Florida, designed for efficiency, convenience and harmony with nature. Instead of driving cars everywhere, the 45,000 residents of Kitson’s Babcock Ranch would ride bikes to school, and walk to the cinema. They’d take a tram to visit friends in another hamlet, on the other side of a lush wildlife preserve.

Seeing Green

Renewables attract utility investment dollars.

New federal policies have opened the gates to utility investments in renewable generating plants. Some states, however, still make it difficult for utilities to put such assets into the rate base. Executives at Duke, OG&E, PG&E and Xcel Energy discuss challenges and opportunities affecting their renewable investment strategies.

Inclining for the Climate

GHG reduction via residential electricity ratemaking.

Energy efficiency holds the key to meeting lofty greenhouse-gas (GHG) reduction goals. Rate design can help—specifically residential inclining block rates should be considered as part of the industry’s efforts to comply with forthcoming GHG targets.

Dealing with Asymmetric Risk

Improving performance through graduated conditional ROE incentives.

Unlike the majority of performance-based regulation plans, alternative design paradigms require less data, by instead allowing firms to reveal performance potential. In an asymmetric environment, regulators don’t have needed information, but that can be overcome with better models and incentives.

The Safety Vote

A prerequisite for sustained nuclear renaissance.

The nuclear renaissance requires safety as its central focus. Industry vigilance at all levels is key to accident prevention, but only favorable public opinion will allow the industry to realize its enormous potential.
