Only two U.S. states, California and Massachusetts, have set targets for energy storage deployments. Now New York City has joined them.

The city government unveiled a storage goal of 100 megawatt-hours by 2020 last week, along with an expanded solar target of 1,000 megawatts by 2030. Storage, with its capacity to integrate variable wind and solar power sources into the grid, is expected to play a critical role in meeting the city’s plans to cut greenhouse gases by 80 percent by 2050.

Storage experts told GTM that this is the first time a city has set such a target.

The city’s target is not a legally binding requirement like California’s. It’s more of an aspirational target with policies designed to make the process easier. 

“With a city-based target, they are also directly responsible for building codes and siting regulations, deployment strategies and even local taxes — and the city can also take steps to adapt all these rules and regulations to accelerate deployment,” wrote Matt Roberts, executive director of the Energy Storage Association, in an email. “The city is able to marshal its forces toward this collective goal, and can more easily adjust the goal based on the observed value delivered in the future.”

The New York City target applies to the full spectrum of storage, including electrochemical and thermal technologies. City officials are targeting storage as a way to reduce demand charges, defer distribution system upgrades, pre-cool buildings and shift solar power consumption.

For all the potential use cases, energy storage is still a bit player in the city’s energy system. A major motivation for the storage target is to make permitting easier, said Daniel Zarrilli, senior director of climate policy and programs with the city.

German manufacturer Stornetic aims to provide its flywheel storage system to wind power plants, it said today at the trade fair, WindEnergy, in Hamburg.

The company said its flywheel system, which turns electrical energy into rotational energy and stores it for later use, allows wind farm operators to balance output fluctuations over the long term.

Stornetic managing director Rainer vor dem Esche said: “Our storage machine EnWheel allows output peaks to be absorbed, thereby making the output of entire wind farms more even and predictable.”

He suggested flywheel energy storage will also be able to provide grid services in combination with wind power plants. “This is an ideal starting point for the challenges of the future,” said vor dem Esche.

Earlier this month, Stornetic announced its EnWheel system has been optimised as wayside storage for the public transportation industry, and particularly for train operators, which can store energy from braking trains at stations to help power them as they depart again.

Stornetic reckons its energy storage solution, designed for more than 100,000 load change cycles, can absorb load changes in the range of milliseconds, and is particularly suitable for applications in which many fast load changes are required.

Only a few weeks after announcing one of the biggest energy storage projects ever, Tesla Energy won again a massive energy storage contract. The automaker’s energy division will supply ‘Powerpacks’ to its energy storage deployment partner, Advanced Microgrid Solutions (AMS), for a major new project: a 7 MW / 34 MWh network of battery systems to support water treatment facilities of Irvine Ranch Water District (IRWD).

The project is part of Tesla’s supply agreement with Advanced Microgrid Solutions signed last year. Under the contract, Tesla will supply AMS with up to 500 MWh of energy storage. It looks like this new project is the biggest between the two companies yet.

Previous projects include a 12 MWh with Cal State University, another one for several office buildings in Irvine, and more recently, a 1 MW Powerpack system inside Morgan Stanley’s San Francisco skyscraper.

In a press release today, AMS describes the new project as “the largest network of energy storage systems at a public water agency in the United States”. IRWD board president, Mary Aileen Matheis, commented on the announcement:

“Our agency has stepped forward with an innovative solution designed to protect customers while helping to reduce and better balance Southern California’s energy demands. This battery storage system – the largest in the nation – provides significant cost savings, enhanced grid stability and contributes to reductions in greenhouse gas emissions and a smaller carbon footprint.”

All the logistics related to water treatment consume a lot of electricity in California. As AMS points out, according to the California Energy Commission, the transportation and treatment of water, treatment and disposal of wastewater, and the energy used to heat and consume water account for nearly 20 percent of the total electricity and 30 percent of non-power plant related natural gas consumed in California.

This new energy storage system should help reduce peak demand for the water treatment facilities and stabilize its energy consumption.

Hawaiian Electric Co. has placed into service its first utility-scale battery energy storage system (BESS), a 1 MW battery located at the Campbell Industrial Park generating station on Oahu.

The BESS is a joint demonstration project by the Hawaii Natural Energy Institute at the University of Hawaii and Hawaiian Electric. It also includes funding from the U.S. Office of Naval Research.

The demo will continue for two years – with a possible extension – to determine the battery’s safety, operating characteristics and effectiveness in helping to integrate more renewable energy on a circuit that already has a high level of solar, the utility says.

“To achieve our 100 percent renewable energy goal, we need to be able to smooth power flowing to the grid from variable renewable generation like wind and solar, as well as shift electricity generated when the sun is shining to when people use the most electricity in the evening,” said Shelee Kimura, Hawaiian Electric’s vice president for corporate planning and business development. “We are working on these capabilities both with larger, utility-scale systems like the BESS units and with ‘behind-the-meter’ batteries at business and residential customer sites – all working in unison to make clean power work.”

The centerpiece of the BESS project is an Altairnano 1 MW/250 kWh BESS, which is housed in a large shipping container. The BESS comprises batteries that store 250 kWh of energy and a corresponding inverter that changes DC to AC electricity so that the battery can export up to 1 MW of power to the grid.

The utility says the quickly responding battery can go from zero to full power output in a fraction of a second, as well as provide 250 kW of power for one hour or 1 MW of power for 15 minutes.

Also being tested are control algorithms that may be used in even larger batteries for power smoothing, voltage regulation and frequency.

California Gov. Jerry Brown and the state legislature signed four bills into law that should positively impact energy storage investment in the Golden State.

Collectively, these bills will grow the behind-the-meter and utility-scale energy storage markets, create new clean energy jobs, reduce distributed energy resource interconnection challenges, and ensure that bulk energy storage is part of California’s renewable energy future, according to a release from the California Energy Storage Alliance.

The bills signed by Brown on Monday include:

·         AB 1637—Increases the Self Generation Incentive Program (SGIP) funding by $249 million, sending a clear market signal to industry stakeholders that behind-the-meter energy storage will play a key role in reducing greenhouse gas emissions and supporting the next-generation electric grid. Thanks to the California Public Utilities Commission’s (CPUC) recent SGIP reforms, 75 percent of the program budget going forward is now reserved for energy storage.

·         AB 2868—Requires the CPUC to direct California’s three investor owned utilities (IOUs) to accelerate the deployment of distributed energy storage by filing applications for new programs and investments of up to 500 MW. This bill directly increases the market for energy storage in California, as the 500 MW is in addition to the 1.325 GW procurement goal that California established in 2013.

·         AB 2861—Authorizes the CPUC to create an objective, expedited dispute-resolution process for distributed, behind-the-meter energy resources attempting to establish an interconnection to an IOU’s electricity distribution network. This bill and resulting dispute resolution process will accelerate and reduce Rule 21 interconnection costs.

·         AB 33 (Quirk)—Directs the CPUC and California Energy Commission to evaluate and analyze the potential for all types of long duration bulk energy storage, such as pumped hydro, to help integrate renewable generation into the grid. This bill ensures broader consideration of bulk energy storage’s unique capabilities and market roles.

September 27 (SeeNews) – New York City has set a new target of 1 GW of citywide solar capacity by 2030, mayor Bill de Blasio announced on Friday.

In 2014, the city committed to installing 100 MW of solar power on public buildings and spurring the installation of 250 MW on private buildings by 2025. Mayor de Blasio said progress made so far has encouraged the administration to adopt the new target, which is equivalent to the power needs of more than 250,000 households.

The mayor also set the city’s first ever energy storage target that calls for the deployment of 100 MWh by 2020.

According to the announcement, New York City’s solar capacity has almost quadrupled to 96 MW from 25 MW since mayor de Blasio took office at the start of 2014. There are 69 MW of private solar installations plus another 17 MW scheduled to be installed, while almost 9 MW of solar has now been constructed on public buildings.

New York City has a target of reducing carbon emissions 80% by 2050.

Separately, de Blasio on Monday announced the completion of a 3,152-panel rooftop solar installation at the Brooklyn Navy Yard.

The US Department of Energy has set aside US$37 million to improve energy storage and conversion technologies in transportation batteries, grid-level storage, and fuel cells.

The department’s Advanced Research Projects Agency for Energy (ARPA-E) will fund 16 new research projects into how new technology, specifically solid ion conductors, can overcome the limitations of current battery and fuel cell products.

Current fuel cells convert chemical energy into electricity, and back again, and can therefore store electricity from intermittent resources like wind and solar power, and also generate it as required from stored energy, whether from carbon free sources or natural gas or hydrogen. At the same time, the inherent limitations of electrochemical batteries has “stifled further innovation,” reckons ARPA-E.

Instead, batteries using parts built with solid ion conductors – solids in which ions can be mobile and store energy – offer a high-performance alternative to traditional liquid electrolytes or expensive materials used in current fuel cell stacks.

The new research will focus on how to overcome associated drawbacks such as low ionic conductivity and expensive processing, and how to finally integrate these parts into energy storage devices. It will also explore how to increase battery energy capacity while preventing short circuits and degradation, and how expensive elements like platinum can be replaced with more common metals.

ARPA-E director Ellen Williams said: “While battery technologies have improved by leaps and bounds over the past few years, there remain some imposing physical and chemical barriers that have stifled further innovation. Solid ion conductors made of affordable, easily produced materials could replace today’s mostly liquid electrolytes and expensive fuel cell parts, helping create a next generation of batteries and fuel cells that are low-cost, durable, and more efficient.”

This week, the Advanced Lead Acid Battery Consortium (ALABC) set out a three-year research programme to improve the performance of lead batteries in energy storage and electric vehicles, and close the gap on lithium-ion in the energy storage and electric vehicle markets.
