Barclays recently downgraded the U.S. electricity sector. That’s right, the whole sector. It’s now listed as “underweight,” meaning that if you were to hold a full portfolio of bonds for the U.S. economy, you might want to be a bit light on U.S. electric utilities, as they might not keep up with the broader economic growth trends. Why? One answer is the disruptive threat of solar-plus-battery systems. From the Barclays report:

Over the next few years… we believe that a confluence of declining cost trends in distributed solar photovoltaic (PV) power generation and residential-scale power storage is likely to disrupt the status quo. Based on our analysis, the cost of solar + storage for residential consumers of electricity is already competitive with the price of utility grid power in Hawaii. Of the other major markets, California could follow in 2017, New York and Arizona in 2018, and many other states soon after.

In the 100+ year history of the electric utility industry, there has never before been a truly cost-competitive substitute available for grid power. We believe that solar + storage could reconfigure the organization and regulation of the electric power business over the coming decade.

If that language sounds familiar, it’s because Barclays’ logic is very similar to that of our recent report, The Economics of Grid Defection, in which we forecasted the declining costs of solar plus storage and the time—coming soon—when those systems could reach parity with grid-sourced retail price electricity in a growing number of markets, including Hawaii, California, and New York. In fact, the Barclays report cites RMI as a key source in several of its analyses that lead to this conclusion.
