Europe’s first grid-scale Tesla Powerpack energy storage system installation was recently officially unveiled in Somerset (England), according to recent reports.

The new Tesla Powerpack installation was designed to store the electricity generated at a solar photovoltaic (PV) project located at the site. The energy storage project, which was developed by Camborne Energy Storage, is intended to provide enough electricity to supply for the needs of about 500 regional households if necessary.

The UK’s Energy Minister Baroness Neville Rolfe attended the recent unveiling event and stated:

“We welcome this exciting project from Tesla and Camborne. Innovation in storage technologies will help manage our electricity grid more efficiently, support greater energy security and, crucially, drive down consumer bills.

“Our upcoming industrial strategy will build on this work further, working with businesses to ensure the UK continues to be at the forefront of low-carbon technology, creating the conditions for future success.”

Business Green provides more: “The industry has been calling on the government to provide a clearer policy landscape for energy storage projects and take steps to accelerate investment in the sector. However, Business and Energy Secretary Greg Clark delivered a boost for the fledgling industry last month, delivering a speech in which he argued energy storage and smart grid technologies would play a critical role in the UK’s energy system in the future and launching a call for evidence on how smart systems should be developed.”

The managing director at developer Camborne Energy Storage, Dan Taylor, commented at the recent unveiling as well: “Camborne is pleased to have developed Europe’s first Tesla grid scale installation by co-locating with a solar farm in Somerset, England. This project is already commercially operational providing low carbon power during times of high demand. Our first co-located site is an early step in the right direction, both for Camborne and for the industry and we look forward to continuing to deliver further low carbon power to the UK.”

PHOENIX–(BUSINESS WIRE)–Arizona Public Service (APS) is bringing battery-based energy storage to the desert through a 4-megawatt (MW) energy storage agreement with AES Energy Storage. The pair of 2-MW AES Advancion^® energy storage arrays, which will provide enough storage capacity to power 1,000 homes, will be deployed as part of the APS Solar Partner Program (SPP) and represent AES’ first installation in Arizona.

APS’s Solar Partner Program studies the use of smart inverters and energy storage to examine how best to integrate solar onto the grid in areas with a high penetration of solar while still maintaining reliability for customers. Through SPP, more than 1,500 customers had photovoltaic rooftop solar panels, totaling 10 MW, installed on their homes at no charge, and receive a $30 monthly bill credit for the next 20 years for their participation. The information APS gains from this study will help craft what the future of renewable energy integration looks like for utilities across the country.

“The best renewable energy is the type a customer never thinks about. A light goes on, a load of towels gets washed and life goes on as reliably as ever before, all powered by the sun,” said Scott Bordenkircher, APS’s director of technology innovation. “This is the future APS looks toward as it studies energy storage.”

The two Advancion battery arrays will be installed in Surprise and Buckeye, which have a total of 120 SPP customers and a high penetration of solar. The batteries will deliver energy to customers at the time of day when electricity is in the greatest demand and is most expensive. By bringing energy storage to these areas, APS can maintain reliable service for solar customers, even when the sun is down and solar panels are no longer producing power.

APS anticipates Arizona’s energy needs will be approximately 25 percent higher by 2025. The company plans to meet 50 percent of that growth with renewable energy and energy efficiency. Through SPP and other groundbreaking pilot programs, APS is taking the lead in Arizona’s deployment of energy storage, advanced inverters, and other controllable resources to manage peak demand better, minimize CO₂ emissions, and solve renewable integration challenges for the benefit of all of APS’s customers.

Researchers have identified a glow-in-the-dark dye as optimal material to develop batteries for energies like wind and solar in the continued quest to develop storage for large-scale alternative energy reuse.

A team of chemists at the University at Buffalo have discovered that a fluorescent dye called BODIPY — an acronym for boron-dipyrromethene — executes two energy-related tasks extremely well: storing electrons and participating in electron transfer. These are exactly the tasks batteries must perform to save and deliver energy, they said, making BODIPY a perfect material to store large amounts of energy in rechargeable, liquid-based batteries that could one day power cars and homes.

Researchers tested BODIPY in what’s called a redox flow battery, which consists of two tanks of fluids separated by various barriers. Flow batteries are one method being pursued by a number of researchers as candidates for large-scale solar- and wind-energy storage. Researchers think these types of batteries will solve the problem of scale and reuse because they can easily be enlarged to store more energy for reuse later in both residential scenarios and for use by energy utilities.

“A flow battery using BODIPY can be used to store any energy source that drives the generation of electricity,” explained Timothy Cook, an assistant professor of chemistry at the University at Buffalo and the leader of the research team. “For example, a solar panel can generate a current and voltage that can be used to charge up the BODIPY dye, but the same battery could easily be attached to a wind turbine, a hydroelectric dam, or even a hand-crank generator. As long as a high enough charging voltage can be created, any source capable of generating electricity can be stored.”

The effectiveness of a redox flow battery depends on the chemical properties of the fluids in each tank. When the battery is being used, electrons are harvested from one tank and moved to the other, generating an electric current that in theory can power from the smallest device to an entire house. To recharge the battery, a solar or wind energy source would force the electrons back into the original tank, where the process of generating an electric current starts over.

Battery storage coupled with low-carbon electricity generation could have helped to avoid the power outages experienced in South Australia earlier this year, according to a study by RES and Lloyd’s Register.

RES Australia technical head Jeremy Moon said the power outages, which were caused by severe storms will mean a detailed review of the Australian state’s power system security policy.

“We understand this requires investment long term and the adoption of new technology and solutions that enable sustainable energy provision now and in the future.”

The two companies said new technology should be planned for now by both government and operators.

Lloyd’s Register energy services manager for the Australian power engineering division Andrew Jones said: “New technology solutions in energy storage can be leveraged to help operators use more cost-effective and locally produced energy.

“This study seeks to open discussions on … how large-scale grid connected battery storage available right now can play a critical role in improving power system events such as those experienced in South Australia.”

The largest battery storage system in the world will also be one of the fastest constructed in history.

In August, San Diego Gas & Electric tapped energy storage company AES to install two energy storage projects totaling 37.5 MW, 150 MWh. When completed, the larger, 120 MWh project is expected to be the single biggest lithium ion battery in service on a utility grid in the world. 

Both battery facilities are expected to be online by the end of January 2017 — nothing short of miraculous in an industry where deploying assets, especially newfangled technologies, can take years. 

And the companies are not alone. Southern California Edison and Tesla announced a 30 MW, 80 MWh project in September that is expected to be online even sooner, and will be the largest operating battery for a time.

The accelerated deployment comes in response to an unprecedented shortage of natural gas for electricity generation in southern California. Last October, a leak at the Aliso Canyon gas storage facility outside Los Angeles caused it to be shut down, constricting fuel supplies for area plants. 

Fearing blackouts, the California Public Utilities Commission quickly mandated a series of mitigation measures, including an expedited procurement for local energy storage resources. The more renewable energy that can be stored during the day, the reasoning went, the less need to fire up fossil fuel generators as electricity demand increases in the evening.

The CPUC order directed the utilities to identify storage projects that could be sited, constructed and put into operation in only a few months. Though the regulators said storage resources must be “cost-effective” compared to other local capacity products, no pricing details for the projects have been released.
