Utility Scale Storage

A much heralded report shows solar and wind will lower wholesale prices, but it also shows a coming evolution in the pricing profile of the grid. These shifts in timing, shape, regularity and length will drive energy storage demand.

The plant, which consists of a 300 kW solar installation and a 1 MW storage system, was built by local power utility Cemig in partnership with Grupo Algar. The project is located in Uberlândia, in the state of Minas Gerais, which is the Brazilian region with the highest penetration of solar and renewables – and a grid that is in a urgent need of improvement.

Kaco developed its Blueplanet gridsave 50.0 TL3-S battery inverter based on experience gained from storage projects in Europe. In pv magazine‘s recent webinar in partnership with Kaco, a number of questions were raised about the device, which the experts now answer.

The installation of an 18 MW battery storage system shows the region’s pioneering work in integrating innovative storage systems to its electricity grid.

The renewable energy developer claims that more opportunities in the UK storage business will be created by the balancing mechanism and growing demand for storage retrofits.

A new report published by the Institution of Mechanical Engineers outlines the potential for power to gas as a technology to support the addition of renewable energy capacity to the grid, and as a storage alternative with advantages over much talked about lithium-ion technology.

Puerto Rico’s Financial Oversight and Management Board (JSF) is examining a series of infrastructure projects that, if approved, would be fast-tracked for development and construction. Some of the PV arrays included in the infrastructure round already have PPAs signed with local utility PREPA. Two include co-located storage.

Swiss storage system provider releases financial report for 2017 showing losses, due to growth capital delay. Project from 2017 pipeline will be finished in 2018, however, promising a strong year ahead. Overall, it expects 100 MWh of operational storage projects this year.

SolarEdge has announced the launch of a new virtual power plant solution promising grid services and reducing the necessity for costly grid infrastructure investments.

The goal of the project, RE 8760 is to show how the storage of renewable energies can make them usable all year round. The generated solar power is stored and converted into hydrogen. It can also be conserved over long periods and used to recharge fuel cell vehicles during the dark winter months.
