A long time ago… 1978 to be exact, the United States was in energy peril. Under the OPEC embargo, oil prices were at an all-time high and continued to increase with no end in sight. In order to spur an increase in domestic energy supply, President Jimmy Carter signed the Public Utility Regulatory Policies Act (PURPA), which required electric utilities to purchase additional energy from independent power producers. Various methods of purchasing this energy emerged, but one method was particularly innovative. The State of California offered independent energy producers, largely wind farms, contracts to sell the utilities energy at a fixed per-kWh price over a long-term contract period.
