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.
