Energy Storage Technologies Enabling More Renewable Power

sjx0323

Solar and wind power provide the means for America to strengthen its energy security, create jobs in growing markets, and improve the environment. Thanks to breakthroughs in energy storage systems, including the first grid-tied solar and storage facility, that potential is getting closer to reality. By combining energy storage systems with smart grid technology, utilities are able to automatically “smooth” the output of energy. This allows intermittent energy sources to be available even when the sun isn’t shining or the wind isn’t blowing.
Across the U.S., Recovery Act funding is allowing 32 demonstration projects, including large-scale energy storage, smart meters, distribution and transmission system monitoring devices, and a range of other smart technologies, to explore the deployment of integrated smart grid systems on a broader scale.
( {2 ?8 ?  N+ aRecently, three of these projects have been recognized for their progress in the development and implementation of energy storage systems.  As the worldwide market for clean energy expands, projects like these are continuing the tradition of American leadership in developing next-generation technologies.
Public Service Company of New Mexico – The PNM Prosperity Energy Storage Project is the nation’s first combined solar generation and storage facility to be fully integrated into a utility’s power grid.  Able to produce and store 500 kilowatts of power, the facility is now helping to meet the electricity needs of customers in New Mexico.  PNM brought the project online in September at a ceremony that featured remarks by U.S Senator Jeff Bingaman and Representative Ben Ray Lujan.  The project received $2.3 million from the Energy Department, which was matched by $3.8 million from PNM, for a total of $6.1 million.
