US power generation contractor and renewable energy company Blattner Energy has completed construction of a 20MW lithium-ion battery storage project.

The Lee/DeKalb energy storage system (ESS) in Illinois, US, is now providing the regional transmission organisation, PJM Interconnection, with the frequency regulation support needed for the area.

The project included Greensmith Energy Management Systems as the integrator of eight containers, 10 feet by 40 feet in size, housing 2.5MW of LG Chem lithium-ion batteries each.

Blattner Energy engineered the system, procured the technology and equipment, oversaw the installation and interconnection of the system technology, as well as completing the testing and start-up activities.

Stephen Jones, director of solar, Blattner Energy, said: “Battery storage will be a key technology in supporting the stability of our grid and the intermittency of some renewable generation sources.”

Europe's biggest electricity storage battery using a 10MW lithium-ion battery array is being built in Northern Ireland (NI).

Plans to provide an extra 250MW of capacity - enough to power 160,000 homes - are in the advanced stages at a site next to Kilroot Power Station.

Energy storage company Beacon Power has estimated that it will build 40MW of energy storage systems by the end of 2015.

Beacon Power CEO Barry Britt said in a Bloomberg interview that the demand for flywheel storage will double over the next years due to the increase of renewable power plants that raise the need for grid stabilising.

Mainstream Renewable Power (MRP) is to test 2MW of energy storage at a 10MW wind farm in Ireland.

MRP will assess the commercial availability of integrating wind generation with flywheels, synchronous condensers and batteries as well as operating the system in the Irish Single Electricity Market. The Irish state agency Enterprise Ireland will assist the “Wind-Storage Hybrid Study”.

Energy storage mandated for renewable energy developments in Puerto Rico

The Caribbean island expects vast growth in the renewable energy sector

Any renewable energy installation on the Latin American island of Puerto Rico must include storage, according to a new rule by a state-owned electricity supplier Autoridad de Energía Eléctrica (AEE). 

Puerto Rico’s Electric Power Authority (PREPA) and the AEE, which is the island’s sole utility provider, have stated for frequency regulating equipment there must be storage equal to 30% of the generating capacity and for ramping services it should be equal to 45%.

The island struggles with intermittent power from renewable sources being connected to the electricity grid— a problem this ruling will address.

The required storage levels of 30 and 45% mean the focus will be on high power options such as flywheels and supercapacitors rather than batteries and electrochemistry solutions.

Renewable energy developers are keen, with 64 already submitting plans that meet the technical requirements. AEE hopes 600MW of generating capacity will be built on the island, this would boost renewable generation on the island from 1% to 6%.

Smart grid trialled in Massachusetts

A smart grid pilot project is to be implemented in Worcester, Massachusetts, US by the National Grid to demonstrate the uses of available technology to improve energy efficiency.

National Grid

Its aim is to provide energy customers with choice and control over the energy they use to empower customers to save energy, while increasing electric service reliability and improving response to power outages.

National Grid has amassed a team of experts to work on the project to construct and deliver an end-to-end smart grid pilot including smart meters, advanced communications technologies, in-home energy management tools, devices for electric system automation, as well as customer outreach and education, project management, integration and evaluation.

Unlike other smart grid trials in the US, customer engagement is key. Customers choose their level of involvement and can receive information about their energy use via the website and downloadable app. Pricing options will be available so customers can save energy and money at different times of day.

National Grid will also be researching the option of full integration of renewable energy sources, installing EV charging stations and connecting energy storage to existing renewable projects.
