Solar energy storage project cost + down or will replace part of coal-fired power plants

Recently it is reported, according to the energy institute of economic and financial analysis ( IEEFA） Survey, in recent years due to the solar + energy storage project deployment costs have fallen sharply, could make the mixed deployment of energy technology instead of the high cost of traditional coal power combination, and save a lot of money.

the study in a recent survey report, utilities after using renewable energy to replace close coal-fired power plants, can save hundreds of millions of dollars.

PacrenCorp company is warren & bull; Warren buffett's Berkshire hathaway energy subsidiary of the company. EEFA said the company is considering the feasibility of close coal-fired power plants, coal-fired power plants and retired in advance some will create a potential benefits for its 1. 8 million customers.

, according to the IEEFA PacifiCorp company coal power plants, although play an important role in power supply, but they can't compete with cheaper and cleaner alternatives. It is reported that the company is the largest in the western United States grid operators, according to the specific circumstances, to close coal-fired plants could reach 2 save cost. 4. 8 billion dollars.

in recent years, people gradually concentrate on a lower cost of solar power generation facilities. New analysis shows that the solar + energy storage projects can be of some new natural gas power plants to compete with the United States, and not just replace some peak power plants.

according to the Fluence of the company's evaluation, leveling of solar + energy storage project of energy costs ( LCOE) The $39 ~ 48 / mw, and natural gas combined cycle ( NGCC) Plants 60-116 dollars/mw leveling of the energy costs ( LCOE) Compared to the far lower. As a reference, according to the statistics PacifiCorp company, some of its leveling of coal-fired power plant energy costs ( LCOE) More than $85 / MWH.

energy company, a subsidiary of Berkshire hathaway did not confirm out how many coal-fired power plants, also did not confirm can replace energy technology of coal-fired power plants. For now, however, some of the company's plan to increase the capacity of hundreds of megawatts of solar + energy storage project deployment.

IEEFA pointed out that other utilities have completed similar measures. Nevada NV, for instance, Energy companies are close some coal-fired power plant, and the company plans to increase capacity to 1 gw of solar Energy and 100 mw battery Energy storage system. At the same time, the Colorado XCEL has submitted the deployment of solar energy, wind energy, battery energy storage system suggestion, the leveling of the average energy costs ( LCOE) When will reach 30 ~ $36 / mw.
