    Optimizing Natural Gas Generation with Energy Storage

    Integrating energy storage with new and existing gas plants can result in improved efficiencies and lower emissions. As the deployment of renewables plus energy storage accelerates exponentially across the country, utilities are recognizing the proven ability of storage resources to supplement and, in some cases, completely replace gas-fired generation.

    Microgrids Restore Water Services in Remote Puerto Rico Communities

    New water and wastewater systems powered by solar plus storage microgrids are reviving life and livelihoods in remote areas of Puerto Rico still struggling to recover from 2017’s Hurricane Maria. In hard-to-reach areas of Puerto Rico where grid power has only recently been restored, six microgrid-powered pumping systems are now up and running, thanks to a partnership between South Carolina-based non-profit Water Mission and Hawaii-based energy storage company Blue Planet Energy.

    Another Breakthrough for Energy Storage? Innovative Auctions Made Prices Plummet

    Rapid and low-cost development of renewables can reduce greenhouse gas emissions, but a lack of energy storage is one factor preventing wind, solar and other clean energy sources from dominating the energy mix. That could change with the use of an innovative procurement method that's generating excitement in the electricity sector: reverse auctions. We must rethink how utilities can grow energy storage capacity affordably. By flipping traditional auction models and harnessing reverse auctions, this technology could take off. We know the approach works because it can be partly credited for the recent surge in global renewable energy capacity.

    8minutenergy: 'We Can Do Solar Peaker Plants at Half the Cost of Gas'

    Many of the most polluting thermal power plants on the US grid today are also the most lucrative to run, but the service they provide could already be done twice as cheaply using solar and storage, developer 8minutenergy has claimed.

    Funding Selections Announced for Innovative Design Concepts for Standard Modular Hydropower and Pumped Storage Hydropower

    The U.S. Department of Energy announced selections for up to $7.5 million for innovations that reduce cost and maximize the value of new stream-reach hydropower development and pumped storage hydropower. Funded projects will develop new design concepts and associated modeling and analysis for standard modular hydropower and pumped storage, respectively. DOE supports technologies consistent with DOE's Advanced Energy Storage Initiative—which drives technology beyond cost reductions toward improved performance and enhanced provision of services to the grid. Selections were made across two topic areas, including scientific analyses that would illustrate how pumped storage hydropower can optimize the performance of the U.S. electric grid system to lower overall system costs.

    SUSI Partners Buys 50% Stake in AMS Commercial Battery Fleet

    Swiss fund manager SUSI Partners acquired a 50 percent stake in AMS’ Southern California portfolio of distributed battery storage systems. The package includes more than 90 lithium-ion systems adding up to storage capacity of 63 megawatts and 340 megawatt-hours. AMS will continue to operate the assets. AMS secured contracts with utility Southern California Edison back in 2014 to install batteries at commercial and industrial sites to lower both customer bills and grid demand in constrained areas. As of mid-March, AMS had brought online 27 megawatts and 142 megawatt-hours of energy storage capacity at 40 sites within SCE territory.

    Pumped Hydro Energy Storage Poised For Global Domination

    A recent study suggests that the Earth holds 530,000 potential sites for pumped hydro energy storage. If that sounds too good to be true, well, maybe. The devil is in the details. On the other hand, the number-crunching does indicate that a massive amount of energy storage capacity is already close at hand, even without new technology breakthroughs.

    Solar + Storage Projects to Drive Utility-Scale Deployment of Batteries: Navigant

    Storage-plus PPAs are already less expensive than the levelized cost of energy for combined cycle natural gas in the United States, according to a recent report from Navigant Research. Lithium-ion batteries are one of the main drivers in the growth of the utility-scale energy storage market, accounting for almost 30% of non-pumped storage capacity developed since 2011, the report found.

    Off-Grid Microgrid: Solar + Batteries + Thermal Generation

    Today’s microgrid installations showcase a variety of configurations and control systems. Commercial and industrial sites are finding innovative ways to power their operations, particularly those in remote locations off the traditional grid. Glasgow, Scotland-based Aggreko recently signed a deal with Gold Fields Australia to deploy a solar-plus-batteries-plus-thermal-generation off-grid microgrid, designed to save fuel, reduce emissions, and boost power reliability.

    The Race to Build the World's Largest Solar-Storage Plant Is On

    The race to build the biggest solar-battery plant is officially on. And the latest to join the competition is renewable energy giant NextEra Energy Inc., which said Thursday that it’ll build a project in Florida that will claim the title of the largest solar-powered battery in the world. The 409-megawatt battery will be added to an existing 74.5-megawatt solar plant on the west coast of the state near Tampa, a company statement shows.
