The smart grid evolution has unleashed opportunities for electric vehicles thanks to technologies that allow them to feed power back into the grid. Utilities and grid regulators are eyeing plug-ins as a flexible resource class helping address the intermittency of renewables and reduce peak power demand.
The dramatic fall in renewables costs have enticed several utilities to look at large-scale investments and also attracted a large number of independent developers seeking to qualify their projects for must-buy obligations under the Public Utility Regulatory Policies Act of 1978 (PURPA). Utilities have complained about having to overpay qualifying facilities and buy electricity even when they don’t need it. The must-buy requirements are also interfering with the utilities’ own plans of developing renewable plants, intensifying the pushback against PURPA.
PJM Interconnection LLC’s annual capacity auction saw clearing prices ramp up 83 percent from a year ago to $140/megawatt-day, rebounding after a sustained fall for two consecutive auctions. Renewables and demand response did surprisingly well especially because they are deemed seasonal assets with limited ability to meet the new stringent performance standards that require year-round capacity. Despite the high prices, the amount of nuclear generation that cleared the auction fell by over a quarter from last year.
The low price of natural gas makes it the go-to choice for ensuring reliability in several states where renewables have captured a large market share. On the other hand, the dominance of natural gas in the power sector is facing a backlash in states that are aggressively pushing for renewable resources. In both cases, however, regulators have become increasingly more concerned about grid reliability as the share of natural gas in the fuel mix continues to grow.
