Wind equipment imports totaled $2.6 billion last year.From Ensia (find the original story here) reprinted with permission. share is much lower for most turbine power components.Ĭhina was the largest foreign supplier of wind power equipment, with imports totaling $428 million in 2019, followed by Spain at $358 million. Domestic manufacturers provided up to 90% of the nacelle or turbine motor housing content in 2019, between 65% and 85% of the towers, and 40% to 70% of the blades, but the U.S. suppliers are faring in international markets for wind turbines. Regulatory and political hurdles have slowed construction of long-distance, high-voltage lines linking prime renewable power areas with urban centers. In parts of the United States where the two power sources compete, “they tend to cannibalize their own market value,” he added.

“There are a number of headwinds that could slow market growth,” Bolinger said, citing the phaseouts of federal tax credits. Overall, wind and solar still total no more than 10% of U.S. The national average for solar purchase price contracts dropped to 2.4 cents per kWh last year, 80% below the price in 2010.

Those states plus Illinois, South Dakota, Kansas and North Dakota contributed 82% of the additions. Texas and Iowa alone added nearly two-thirds of the 9,000 MW of new wind farms in 2019. Great Plains and Upper Midwest, where wind conditions are strongest. The low average is dominated by cheapest prices in the U.S. The national average price of wind in purchase price agreements has dropped below 2 cents per kilowatt-hour. Whether wind or solar power is cheaper “depends on which region of the country you’re looking at,” Bolinger said. Yesterday’s report documents how geography and state policy have dictated wind and solar power development. The advance is much smaller in Texas, which pays generators for energy, not capacity, this report said. In California, hybrid solar and wind projects with batteries have greater market value than stand-alone solar and wind projects, because developers receive payments for both energy delivered and capacity held in reserve.

Solar and battery hybrid projects are eligible for the federal investment tax credit, but wind and battery pairings are not, and that may make the solar pairing more economical in some locations, said Ryan Wiser, head of the lab’s electric markets group. There are also limitations to hybridization, however, and market rules and policy incentives can make or break the finances of a project.” Researchers for Lawrence Berkeley and the Electric Power Research Institute also reported in March that “interest in hybrid plants is high, and that hybridization can offer benefits relative to stand-alone plants.

solar projects are combined with batteries, but in California, the figure is nearly two-thirds, according to the lab. The curve describes the fast ramp-up that natural gas generators must deliver to offset the drop in solar power then.Ī quarter of all proposed U.S. Hybrid units are helping California deal with the “duck curve” challenge at sunset on hot days when power demand is still near its daily peak. New solar projects are benefiting from a growing trend led by California toward “hybrid” combinations of renewable generation with battery storage, the lab said. Several market studies predict wind generation will grow by half that amount in the next few years, the lab reported. New additions of utility, commercial and residential solar units would stay near 20,000 MW a year for the first half of this decade, aided by a longer phaseout of federal tax incentives than wind projects receive, LBNL said, citing a Wood Mackenzie analysis. While solar power is still more costly than wind, except in California, solar delivers a greater net financial benefit to customers on average, he said. As recently as 2016, proposed utility scale solar energy projects trailed both wind and natural gas in number.Įven though some renewable projects in the queues will not be completed, solar’s advantage is clear, Bolinger said.

grid networks, said Mark Bolinger, an author of the study, a 14th annual LBNL update on wind and solar energy. New wind turbine plants added 9,000 megawatts of generation capacity in the United States last year to bring the total to 106,000 MW, versus 6,000 MW in new utility-scale solar plants, making that total 29,000 MW, the report said.īut “solar has rocketed to the top” on lists of proposed solar and wind projects seeking advance approval to tie into U.S. Wind power is still the dominant renewable energy source nationwide. The competition between wind and solar power in the United States is breaking decisively in solar’s favor, according to a new report from Lawrence Berkeley National Laboratory.
