Big utilities are afraid of distributed generation:
“Across the country state legislatures and/or utility regulatory commissions in more than 30 states are evaluating current net metering policies and are taking steps to update them to eliminate the shift in costs from customers with private solar systems to customers without these systems,” said Jeff Ostermayer, a spokesman at Edison Electric Institute (an association representing investor-owned electric companies in the United States) by email.
But the Brookings review suggests that these types of policy changes may not be warranted after all — that, rather, the benefits provided by rooftop solar actually outweigh their costs. The review points to state-commissioned studies from Vermont, Mississippi, Minnesota, Maine and even Nevada that suggest net metering results in net benefits for all energy customers.
EEI is likely the largest and most prolific industry-funded group opposing rooftop Solar, but other groups have been springing up like weeds in the last few years. Which gives you an idea of the huge amount of money being spent by utilities to undermine this (much needed) trend in energy production and use. Their argument is almost completely without merit, because they only focus on Solar net-metered customers not "paying" for grid use and maintenance. But in reality, the surplus power generated from rooftop Solar is bought and used by another customer within a few blocks of the point of generation. As opposed to power generated 50 miles away, traveling a grid that loses up to 17% of that power along the way. Get it? The utility actually saved money (profits) from that transaction, because it's more efficient and reduces the long-distance demand:
