In November 2015, the Utah Public Service Commission asked Rocky Mountain Power to study the costs and benefits of net metering in Utah, and based on that, to propose updated net metering rates. After analyzing a wide range of energy consumption and customer use data over the last year, the study made two important findings: 1. While rooftop solar customers take less energy from the power grid than other customers, the cost of serving solar customers is nearly the same because they still need to use the power grid and rely on Rocky Mountain Power’s customer service. 2. Overall, net metering customers pay about $400 less per year than the actual cost of providing service for items such as energy grid maintenance, customer service and more.
