"...the confluence of low natural gas prices, high electric rates and the need for resilient power is motivating many commercial and industrial customers across the United States to return to Edison's original concept, where power is generated closer to where it is used. The drivers for this trend of on-site generation are perhaps strongest back in Edison's original test city of New York, where a combined heat and power (CHP) renaissance is underway."
