Electricity: Centralized or Distributed?

As the cost of on-site solar, wind, and micro-combined heat and power drop in cost, more consumers are producing their electricity on site and sending any excess to their utilities. Their electric meters run backwards and they are credited for the electricity in a process called net metering.
Utilities are becoming alarmed that they will lose profits and that costs are being shifted in ways they have not previously experienced. So they do what every entrenched monopoly does—they commission studies to show how net metering hurts other ratepayers, especially poor people. But just like the tobacco and coal industry study findings that their products are harmless, these utility studies are nonsense.
Electric utilities have also gone to their legislatures or regulatory commissions to impose “standby charges” to compensate for this cost shift. But actually, net metering is better for ALL ratepayers, and studies are delineating those benefits. If electric utilities overplay their hands, more consumers will turn to energy storage, which allows customers to store their electricity (I do this at my home and office buildings). The downside for the utilities is that they lose access to available, reliable in-service regional electric power.
Midwest Energy News reported on February 27, 2015, about a cost-benefit study on net metering in Missouri. The study concluded that the practice is beneficial for all customers, regardless of whether they have rooftop solar or not. “The study used values for two costs and two benefits and concluded NEM’s (net energy metering’s) ‘net effect’ is positive. The typical solar owner pays only 20% less in fixed grid costs, and costs the utility an estimated $187 per interconnection. Solar owners benefit the system through reduced emissions and energy costs. Even accounting for a range of utility costs, including administration and the shift of some infrastructure expenses, the Missouri Energy Initiative study of NEM from 2008 to 2013 reached a similar conclusion as NEM studies for Vermont, New York, Texas, and Nevada.”
One of my Virginia solar colleagues commented, “If you dig into the reports (I just looked through Mississippi and Vermont), they calculate the actual long-term value of solar. In Vermont today, that is $0.22 per kilowatt-hour (/kWh). In Mississippi, it’s $0.17/ kWh. In Mississippi, though, net metered customers are only getting $0.12 savings for their credits. So really, it’s the solar homeowners who are subsidizing the utilities.”
