United States: household distributed PV “runs” traditional utilities

Polaris solar PV net news: according to the Rocky Mountain Institute (RMI), a report by 2030, with more and more residents deployed solar power generation and storage facilities, United States Northeast Utilities would lose about half of its revenue.

Energy consultant in Snowmass, Colorado said in an earlier report by: residents and business customers abandon traditional centralized utility power supply, opting instead of distributed renewable energy more economically, it could erode the region’s utility tariff revenue of about $ 34.8 billion. Amount of electricity sales to consumers to reduce, even affected utility companies is planned in the 2010-2030 mountain power project finance capability.

Falling cost of solar panels, innovative lease model and advance payment-free installation to detonate the American enthusiasm for installing photovoltaic roof, average annual growth of 50% over the past 3 years. Traditional utility companies in some States want to increase tariffs for self-generating users, they said received funds will be used to build a flexible grid system, allow users to sell excess power, and again a situation in their private systems rely on power grid.

The report’s co-author James Mandel and Leia Guccione said: “for shareholders and of the traditional centralized power generation and transmission operators, we find that is not good news. “They think, utility companies are struggling to find new business models and bring them in your new network of traditional systems.


A Washington institution representing the traditional public utilities–Edison Electric Institute, is not the first time to comment on the report. Connecticut, Massachusetts and New Hampshire, a major supplier of Eversource energy companies main supplier Consolidated Edison Company of New York also did not comment on the report.

United States national grid Corporation Chairman Rudy Wynter said Federal Regulation: “the report may overestimate the attractiveness of local power generation. “United States national grid for 3.4 million customers in New York, Massachusetts and Rhode Island will supply electricity.

Wynter said, “solar and wind power only on large-scale deployment of utility-grade can be more economical. ”

Report to the shareholders of the power plant in advance “real risk”, the proliferation of distributed PV generation and energy storage systems, future-oriented competitive electricity markets, which will make the traditional utility assets impairment.

Network charges

Including SolarCity, NRG Energy, SunEdison, and many of them will sell solar photovoltaic systems, customers reduce its reliance on traditional public utility electricity.

Shareholders of public corporations are planning to lower sale price of photovoltaic power generation, and to introduce a monthly network access fee. Last month, SolarCity sued in Arizona, requires the distributed solar power users pay the minimum each month $ 32.44, paying for the cost of grid connection and.

Report, New York, California and Hawaii consumers will find that 10-15 years in the future, select PV + energy storage system will be cheaper than relying solely on public utility power grid. State regulators have already begun thinking about how to protect traditional power company profits improving deployment of PV + energy storage devices.

California utilities shareholder PG&E and Edison International said that as more and more consumers are deploying PV + energy storage facility, utility companies would seize the growth opportunities, the investment to upgrade the power grid, so that power can flow in both directions.

“A lot of debate about the new regulatory framework and the fee structure will be faster than it is now expected to become a reality,” Guccione said in a telephone interview, author of the report. “Persist even now people will actually have to pay a heavy price. ”
