    6. Eversource Turns to Non-Wires Solution in Outage-Plagued New Hampshire Town

      Eversource Turns to Non-Wires Solution in Outage-Plagued New Hampshire Town

      Eversource Energy is turning to efficiency and energy storage to help maintain reliability in a small, rural New Hampshire town prone to outages, rather than spend $6 million to construct a new 10-mile distribution circuit. The largest component of the Westmoreland Clean Innovation Project is a 1.7 MW / 7.1 MWh lithium-ion battery, estimated to cost $7 million. Despite being costlier than the new-circuit alternative, the utility says the project will deliver savings to Eversource customers by reducing peak costs. The project aims to improve service in the town, which is served by a single major power line.

    9. Energy Storage is Critical to Microgrid Development: Microgrid 2019

      Energy Storage is Critical to Microgrid Development: Microgrid 2019

      Microgrids increasingly depend on solar-plus-storage — or the ability to generate solar power on site and to store excess electrons in batteries that would release that energy when it is needed. Energy storage provides a Swiss army knife of services, from shaving peak load to storing and injecting wind and solar electrons onto the grid. It enhances reliability while also increasing efficiencies and allowing for more green energy on the grid.

    11. Better Energy Storage will Raise the Bar for Renewables

      Better Energy Storage will Raise the Bar for Renewables

      Solar and wind are clearly the future of energy, yet the adoption of renewables has been largely constrained by their intermittent nature. Innovations in energy storage technology might change that. In the last year alone energy storage has grown by 6 GWh of capacity globally and it has the potential to grow 13 times present levels by 2024. With energy storage costs having fallen by 85% since 2010, solar-plus-storage suddenly becomes a great option, especially when combined with the fast growth of solar and wind markets. All these developments are set to remake the renewable energy landscape.

      Hot Dam: How Hydro Storage Will Allow Uruguay To Join The 100% Renewables Club

      In recent years, 50-60% of Uruguay’s power has been generated from the country’s four hydroelectric dams on the River Uruguay. Most of the remainder comes from renewable energy sources such as solar panels and wind turbines. That combination has turned the country into the world’s poster child for low-carbon energy. The one remaining sticking point is storage. Without it, renewables can only be used as they are generated. Hydro storage provides reliability and flexibility to a renewables-based grid by creating a huge, continuously rechargeable battery that is entirely powered by the elements.

      Battery On The Berm: The Ludington Pumped Storage Facility

      The Ludington pumped storage facility is essentially one of the world’s largest batteries. Consumers Energy gets its base load of energy from its coal and gas plants across the state. When the energy demands peak above that base load, they need places like the Ludington Pumped Storage Facility to pick up the slack. In just a matter of minutes, they can open up the gates, get the water flowing through the turbines and pick up that amount. When the demand is low, like at night, they will start pumping water back in to the reservoir, getting ready for that next call.
