Convergent Buys Up 40MW of Flywheels in New York and Pennsylvania

on May 9, 2018

Energy-Storage-NewsConvergent Energy + Power, a US-Canadian project developer which has attracted investment from the venture capital arm of Statoil, has acquired 40MW of flywheel energy storage already in operation in grid-balancing markets in New York State and Pennsylvania.

Rockland Capital, an investment company focused on the energy sector in North America, acquired renewables integrator Beacon Power in 2012 and in doing so created a limited liability entity, Stephentown Spindle, to develop a 20MW flywheel project in Stephentown, New York. Spindle then went on to also develop the second 20MW flywheel project, Hazel Spindle, in Hazle Township, Pennsylvania.

The former went into operation in 2011, the latter in 2014, providing frequency regulation to the transmission networks of PJM Interconnection and New York ISO (Independent System Operator), bringing Convergent’s portfolio of energy storage assets in North America up to 66.5MW across seven projects.

The flywheels, which store power as rotational energy, can respond to grid signals in a fraction of the time it takes fossil fuel generators or nuclear, and do so cleanly. While not as fast-responding as lithium batteries, the wheels, in this case 400 of them weighing five tonnes each, experience little degradation over time and theoretically require less maintenance. With increasing amounts of variable renewable energy generation in North America, there is an increasing need to balance the frequency of grids. The flywheels were manufactured by RGA Investments, an arm of advanced engineering and technology group RGA Labs.

Convergent claimed the flywheels help support the local transition away from fossil fuels and towards renewable energy and also support the local grid at much less expense than the equivalent in transmission or distribution infrastructure upgrades. The company said it manages “all aspects” of development for its customers, which include utilities, grid operators and industrial entities.

EDF and STORNETIC Partnership Project: STORNETIC Flywheel Energy Storage System Delivered to EDF

on September 13, 2017

business-insiderStorage device DuraStor® reaches EDF Concept Grid site near Paris where it will serve within advanced smart grid project  

For the first time STORNETIC has delivered a Flywheel Energy Storage system to EDF. The storage device DuraStor® has safely reached the EDF Concept Grid site in Moret-sur-Loing near Paris where it will serve within a joint project on advanced smart grid storage solutions. The project serves to assess the performance of flywheel energy storage technology facing the demands of a modern grid environment and special customer requirements.

“We are very excited to test this innovative technology in our experimental facility of Concept Grid; the system has been successfully installed and connected to the grid. Thanks to the unique EDF experimental facility of Concept Grid, we will reproduce real distribution networks and test DuraStor® in fully controllable conditions of operation and thus demonstrate the interest of this technology in the future smart grids,” says Etienne Brière, Renewables and Storage Program Director at EDF’s R&D.

Flywheels for short term energy storage  
The DuraStor® by STORNETIC is designed for industrial customers with many charging and discharging cycles. Unlike other storage technologies the flywheel keeps its full capacity over the complete lifetime while combining the advantages of mechanical energy storage, such as sturdiness and endurance, with the advantages of modularity and rapid installation. The device operates purely mechanically – without the use of chemicals – and is made of materials that are fully recyclable. As an innovative short term energy storage solution it enables operators of micro grids around the globe to transform electric energy into rotation energy and store it.

Flywheel energy storage device to be installed near Paris

on November 22, 2016

Electric-Light-and-PowerEDF and Stornetic have launched a joint project on advanced smart grid storage solutions. The project serves to assess the performance of flywheel energy storage technology facing the requirements of a modern grid environment.

As part of the collaboration, Stornetic is going to deliver a DuraStor Energy Storage device to EDF by June 2017, which will be installed at the EDF Concept Grid site in Moret-sur-Loing near Paris.

The development of variable renewables has raised a lot of new requirements to generation facilities and grid operators. “We believe that energy storage solutions will play a key role in the upcoming transformations of the electrical systems. Thanks to the unique EDF experimental facility of Concept Grid, we are able to reproduce real distribution networks and test innovative electrical equipment in fully controllable conditions of operation. Thus, as one of the promising storage solutions, we are very excited to assess the performances of the Stornetic technology regarding various applications such as renewables smoothing or frequency regulation” says Etienne Brière, Renewables and Storage Program Director at EDF’s R&D.

The DuraStor by Stornetic enables grid operators to transform electrical energy into rotation energy and store it. It is a durable solution, designed for more than 1,000,000 charging cycles and retains its full capacity over its complete lifetime. It combines the advantages of mechanical energy storage, such as sturdiness and endurance, with the advantages of modularity and rapid installation. The device operates purely mechanically – without the use of chemicals – and is made of materials that are fully recyclable.

“We are thrilled to see EDF having decided for our solution”, says Stornetic’s Director Olivier Marques-Borras. “We believe that our flywheel technology can make a real difference. It is ideal for customers with many charging and discharging cycles. This makes it highly interesting for operators of micro grids all around the globe. At the EDF Concept Grid site we are going to assess the advantages of our technology. We believe that flywheels will be part of the future of short term energy storage”
