A US Smart Grid will be only work if it is created with “clear policies, empowered customers and demonstrated cost savings” according to a new report.

Researchers at Vermont Law School’s Institute for Energy and the Environment investigated the legal, policy and regulatory obstacles to introducing Smart Grid technology.

It conducted case studies of seven US utilities – including Commonwealth Edison, Long Island Power Authority and San Diego Gas and Electric – in an attempt to pinpoint best practices that could be replicated nationwide.

Researchers concluded that states that have clear smart policies, such as California, are moving steadily towards their goals; statewide collaboration can spur progress and innovation; and without clear cost recovery policies for utilities, the Smart’s Grid’s reliability and environmental benefits will not be fully realised.
