Global renewable energy development company, SunEdison, signed a 10-year agreement with Ontario’s Independent Electricity System Operator (IESO) this past December to supply 5 MW (or 20-MWh) of battery storage to the province. The Ontario IESO works at the heart of Ontario’s power system, and is responsible for making sure everyone in the province gets the electricity they need,…
Another recent low-cost battery offers to store renewable energy
Wind and solar energy projects are growing at a respectable clip. But storing electric power for days when the air is still or when the sun goes down remains a challenge, largely due to cost. Now researchers are developing a new battery that could bring the price of storage to more affordable levels. They report…
Advancing power storage with ultracapacitors
When considering energy storage, chances are you aren’t thinking about the pitch-control system in a wind turbine. But these systems, standard in most utility-scale turbines, include an important power-storage component. Because of the large rotors on these wind turbines, blades are exposed to wind speeds that vary from the highest point to the lowest. This…
