A study by Navigant Research indicates nearly two GW of energy storage systems have been announced worldwide so far this year.

Navigant said new project announcements are coming on a regular basis, and various companies are exploring new ways to make energy storage systems profitable.

Lithium ion batteries remain the top method of energy storage for new projects, accounting of 83 percent of the new capacity through the third quarter of 2016.

Distributed energy storage systems are becoming more popular, as they accounted for 14 percent of new energy storage projects so far.

“DESSs are generally much smaller than utility-scale systems and are expected to thrive as they become more cost-effective and productized, leading to more streamlined installation and opening new markets,” said Ian McClenny, a research associate with Navigant Research.

Projects using flow batteries and hybrid battery systems are also becoming more common.

The largest solar and energy storage system in Connecticut was recently opened, by the Connecticut Municipal Electric Energy Cooperative (CMEEC) and Norwich Public Utilities (NPU), in partnership with SolarCity and Brightfields Development.  NPU will now provide its customers with solar power as part of its current electric service and without an additional charge. When added to NPU’s existing hydropower capabilities, the NPU energy portfolio is now nearly 20% renewable.

The 4.7 megawatt Mountain Ash Solar Farm includes more than 15,000 solar panels on a 15-acre site, and is expected to produce enough solar energy over the next two decades to power more than 8,400 homes for a year.

As highlighted in the full press release on NPU’s website, the energy storage system installed at the Mountain Ash Farm is SolarCity’s first project to utilize its proprietary GridLogic control platform to provide capacity services to a utility. The 750 kilowatt energy storage system will provide up to 3,000 kilowatt hours of electricity. SolarCity is providing engineering, installation, and maintenance of a battery storage system, which through the Gridlogic platform, allows CMEEC to remotely and instantaneously dispatch stored solar energy in the event of increased demand or large-scale power outages in its service territory.

Under the terms of the 20-year solar purchase power agreement with SolarCIty, CMEEC will utilize the clean solar energy produced at Mountain Ash Farm. The energy storage system, also financed by SolarCity, will allow CMEEC to pay a fixed-rate for capacity, which lowers its operating costs and helps keep prices stable for its member organizations and their customers.

{Editor’s Note: The NPU facility at Mountain Ash Farm was highlighted in the Nov. 7, 2016 NY Times’ article: “Power Couple: Tie-Up Shows How Batteries and Solar May Link” more recent NY Times article, which also provides updates on the Tesla/SolarCity merger.]

Tesla has acquired German engineering firm Grohmann Engineering to form a new advanced automation segment of its business, producing manufacturing equipment for its factories in the US.

It is believed the acquisition and subsequent creation of Tesla Grohmann Automation will boost production of its stationary storage as well as its automotive segment, with the parent company anticipating the hire of 1,000 advanced engineering and skilled technicians in Germany. This would be in addition to the existing 700 employees on Grohmann’s books.

Tesla reiterated in a blog post announcing the news that it has set itself a target of producing 500,000 cars annually by 2018, which by then will include the Model 3 “affordable” EV with a range of over 200km.

“Accelerating a sustainable energy future is only possible with high-volume factories,” the post read.

“At very high production volumes, the factory becomes more of a product than the product itself.”

While a spokesperson confirmed that production of the cars and stationary storage Powerwalls and Powerpacks will remain in the US, including its EV factory in Fremont, California and the Gigafactory in Nevada, some of Tesla’s automated manufacturing systems will be designed and engineered by the Grohmann team. Tesla said it expected to add more locations for Tesla Grohmann Automation centres in future.

The Grohmann acquisition remains subject to approval by regulators with Tesla hoping to close the deal early next year. The news follows the launch of the second-generation Powerwall residential and Powerpack commercial and industrial storage systems, both with significantly increased energy density from previous models, as well as solar roof tiles in a joint undertaking with SolarCity. Tesla and SolarCity could merge later this month, with shareholders voting on 17 November.

BOULDER, Colo.–(BUSINESS WIRE)–A new report from Navigant Research examines global energy storage projects, providing a database of more than 1,200 projects encompassing more than 43,000 individual systems, with an analysis of regional technology choices and market shares.

Market activity in the energy storage sector continues to grow, with new project announcements occurring routinely and industry players exploring innovative business cases to make energy storage systems (ESSs) profitable. Nearly two gigawatts (GW) of new ESSs have been announced in 2016 so far, and several projects have reached commercial operation this quarter alone. Click to tweet: According to a new report from @NavigantRSRCH, lithium ion (Li-ion) batteries remain the leading energy storage technology for new projects worldwide (excluding pumped hydro storage), accounting for 83 percent of newly announced ESS capacity through 3Q 2016.

“While Li-ion leads in terms of technology, distributed energy storage systems (DESSs) are becoming increasingly popular in several regions, accounting for around 14 percent of new system capacity announced in 2016—the highest percentage of any year on record,” says Ian McClenny, research associate with Navigant Research. “DESSs are generally much smaller than utility-scale systems and are expected to thrive as they become more cost-effective and productized, leading to more streamlined installation and opening new markets.”

Projects using flow batteries and hybrid battery systems are also becoming more popular, according to the report. These systems are advantageous in that they can provide multiple services to the grid based on dynamic conditions and specific requirements.

The European-funded project will allow participating homes to store excess solar energy in either batteries or hot water tanks for use in the evenings.

Energy storage technology means less reliance on the grid, creating more sustainable communities. The project will also research the issues and parameters of community energy schemes that sell and share self-generated energy from homes in the project.

It will use ‘communal batteries’ as part of this, located in the area’s schools.

Some 37 homes from across the neighbourhood will take part in the project, and 22 of these will receive technology that will allow them to use significantly more of their clean green energy generated from their own solar photovoltaic (PV) panels. Installation begins early 2017.

This innovative project, SENSIBLE, which aims to show positive ways to reduce fuel poverty, is led by The University of Nottingham and MOZES, the Meadow’s ‘Community Energy Group’.

The Meadows is an ideal community to trial the technology as it has a large proportion of houses across different tenures, housing types and ages and socio-economic groups installed with solar PV panels following the receipt of a Department of Environment and Climate Change grant in 2010 which made it one of 11 UK Low Carbon Communities.

Its residents are therefore relatively used to ‘test’ initiatives regarding energy and efficiency because of this and the related work MOZES does within the community. This range of demographics relating to how and when electrical energy is used in The Meadows will go on to help the SENSIBLE researchers to draw more accurate conclusions from the gathered data.

The first energy storage project in the Midcontinent ISO is up and running, but it is not being compensated for the services it is providing in the MISO footprint.

Indianapolis Power & Light’s 20 MW, 20 MWh Harding Street storage facility went into service in May, but as valuable as those batteries may be, there is no regulatory path for IPL to get paid.

IPL is working on that problem, but it could be a heavy lift.

Late last month, IPL filed a complaint with the Federal Energy Regulatory Commission, asking the regulator to find that MISO’s rules for energy storage are deficient and should be revised.

The fast track complaint seeks three changes. IPL wants to see MISO revise its tariff for primary frequency regulation (PFR) by unbundling it and paying locational marginal prices (LMP) for the service under its own schedule. Because it is an automated function, current rules do not consider PFR to be a market operation because there is no bid and dispatch function.

The utility also wants MISO to revise its dispatch protocols for secondary frequency control. As currently designed, lithium-ion batteries wanting to participate in the MISO market would be forced to operate in a way that would degrade their batteries quicker than usual.

Those protocols were designed for flywheel storage devices, but forcing li-ion batteries to provide one hour of injection and one hour of withdrawal prevents batteries from “being used in the most valuable manner,” the filing says.

Cell life of the Harding Street battery would be reduced to three years, instead of the 10 years if it were cycled properly, IPL argues. IPL also wants to be paid, not charged, the LMP when withdrawing power from the grid in response to frequency deviations.

Battery manufacturer and developer NEC Energy Solutions is to supply Southern California Edison (SCE) with its first grid energy storage pilot system under a procurement programme established last year.

The NEC ES GSS grid storage solution is a ‘plug-and-play’ procurement strategy being used by the Californian utility to pilot energy storage as a grid stabilising solution. It allows SCE to employ energy storage with a variety of features and configurations on-demand and could be installed almost anywhere across the state to support SCE pilot programmes.

The first storage system delivered under the procurement programme will include 3.4MWh of containerised lithium-ion batteries, a 3MW power conversion system and NEC Energy Solution’s software controls.

The energy storage system will be installed to prevent conventional grid upgrades that are becoming increasingly challenging, particularly in dense urban environments such as those found in SCE service territory. NEC Energy will also provide service and maintenance offerings to the utility for the upkeep of the energy storage system.

“Commercialisation of energy storage in a way that allows quick and easy procurement has always been a goal of ours,” said Bud Collins, CEO, NEC Energy Solutions, in a statement. “We worked extensively with SCE on this innovative programme to make energy storage transactional while ensuring safety, reliability, and cost-effectiveness of the technology. Programmes like this will make energy storage – a fast, flexible, clean, and dispatchable resource – an integral part of the grid.”

Recently, SCE and GE announced that they plan to install the world’s first battery storage and gas turbine hybrid. SCE is one of California’s three investor owned utilities that make up around 75% of the state’s electricity supply andare bound by AB2514, the mandate that orders the utilities to put 1.3GW of energy storage on the grid by 2020.
