French firm Voltalia has started building the largest energy storage system in French Guiana made up of two separate lithium-ion batteries.

The Mana Stockage facility with 10MW / 11.3MWh of storage is located close to Voltalia’s under-construction Savanes des Pères project within the Toco storage complex, which couples a 2.6MW / 2.9MWh battery system and a 3.8MW solar plant.

The new project was a winner in the French Commission for Energy Regulation (CRE) call for projects in 2018. In fact, the Mana Stockage faciluty represents 90% of the storage capacity awarded for French Guiana.

One battery unit of 5MW / 4MWh capacity will be used to regulate the frequency of the network, while the second unit of 5MW / 7.3MWh capacity will be used for arbitrage.

Together with the neigbhouring Savane des Pères project, the storage and PV systems are due for completion in the second half of the year

Sébastien Clerc, CEO of Voltalia, said: “Battery storage is a nascent market: it represented less than 1% of the renewables market in 2018. With the drop in batteries prices, but also in the cost of other storage technologies, the sector will experience a fast and sustainable growth. Active in the market since 2017, we continue to build an expertise on both small and large storage capacities, a strategy which will open up many opportunities.”

A new research network is being formed to create solutions for ‘urgent’ challenges in energy storage.

The Supergen Energy Storage Network+ 2019 will be led by the Birmingham Centre for Energy Storage (BCES). It aims to support collaborations and innovative research, whilst connecting researchers from diverse disciplines.

The network will primarily focus on creating an accessible map and directory of energy storage expertise to allow for greater collaboration in the industry. It will also look at mentoring early career researchers, improving diversity and inclusion and facilitating stakeholder engagement and knowledge transfer across discipline and sector. Feasibility studies will also be funded by the network.

The Engineering and Physical Sciences Research Council has provided £1 million in funding for the network, which includes a partnership of 19 investigators from 12 UK institutions. A further 60 organisations both from the UK and abroad are also supporting the network.

Professor Yulong Ding, BCES director and principal investigator of the network, said: “Our aim is to create a dynamic, strategic and sustainable platform, which connects and serves people from diverse backgrounds across the whole ES value chain.

Navigant Research has published a new report discussing how energy storage value-added services (VASs) have evolved and contributed to the growth of the energy storage market and towards the reduced customer risks.

VASs enable energy storage projects to be bankable as consumers and investors are generally unfamiliar with the technology.

According to the study, VASs remain an important component of new energy storage projects and present opportunities for innovative companies to establish a leadership position.

In order to stay competitive, Navigant Research recommends energy storage system providers to continue to innovate on their existing VASs and maintain flexibility in their offerings to design a VAS programme to suit the needs of their customers.

Vendors of emerging technology (such as flow batteries) need to offer VASs that can reduce the perceived risk to customers by taking on the performance risk themselves.

Alex Eller, senior research analyst at Navigant Research, said: “VASs include operations and maintenance (O&M), warranties, and performance guarantees, which are collectively fundamental components of any project proposal.

“Energy storage VASs have played a fundamental role in the growth of the energy storage industry over the past decade and will remain an important component of new projects.”

BERLIN (AP) — Amid the hum and heat of Berlin’s Reuter thermal power station stands a shining contraption that looks out of place in the decades-old machine hall.

Its silver pipes and vats contain a substance that Vattenfall, the plant’s operator, says could become a key ingredient for a fossil fuel-free future.

The energy company, together with a Swedish start-up, is testing the use of salt — though not quite the common table variety — to store heat, which accounts for more than half the power consumed in Germany.

If it works well, the system could help solve a problem posed by renewable energy sources like wind and solar the world over: they are unreliable, meaning they sometimes generate too much, and sometimes too little power.

“Germany currently has enough installed renewable energy capacity to produce twice as much as it needs, it’s just not constant,” says Hendrik Roeglin, who oversees the salt storage project for Vattenfall. Rival utility E.ON recently calculated that solar and wind power generated up to 52 gigawatt hours of electricity during peak daylight hours on Easter Monday. Germany’s energy consumption at the time was just 49.5 gigawatt hours.

“With many facilities like this one, in theory you wouldn’t need gas or other fossil fuel backups,” said Roeglin.

Phasing out nuclear, coal and gas is an ambitious undertaking for a heavily industrialized country such as Germany. The government has set a deadline to shutter all the country’s nuclear plants by 2022 and stop burning coal for electricity by 2038; gas will be a stop-gap technology until a way is found to rely wholly on renewable technology sometime around the middle of the century.

The plan, known as the Energiewende, or energy transition, is being closely watched by other countries trying to figure out how to curb greenhouse gas emissions and meet the Paris climate accord that aims to keep global warming well below 2 degrees Celsius (3.6 Fahrenheit).

Experts agree that a range of technological solutions will be necessary to replace fossil fuels, some already existing and some still at the experimental phase. California-based automaker Tesla has already shown in Australia that it can provide large lithium-ion battery systems to stabilize electricity grids.

In December 2018, the Union of Concerned Scientists convened a diverse group of stakeholders to discuss the equitable deployment of energy storage. The group—which included environmental justice and grassroots organizations, policy experts, industry, labor, consumer advocates, faith groups, and renewable energy advocates—collectively developed a set of consensus principles for equitable storage deployment.

The principles—which have been signed by 26 participating organizations—are intended to help state policymakers promote energy storage, address the needs of disadvantaged communities, and avoid inadvertent harm. The stakeholders grappled with the following questions:

How can storage be deployed to reduce emissions and improve air quality?
How can storage make communities and residents more resilient to disasters and power outages?
How can storage promote local economic development and job growth?
How can storage help accelerate greater levels of renewable energy on the grid?
How can storage help reduce electricity bills?
How can policymakers ensure that communities have a seat at the table?

The Union of Concerned Scientists convened a group of diverse stakeholders, including environmental justice and grassroots organizations, policy experts, industry, labor, consumer advocates, faith groups, and renewable energy advocates, in December 2018 in Chicago, Illinois, focused on the equitable deployment of energy storage. Energy storage is poised to expand dramatically, transforming the way we produce and use electricity. It is critical that this expansion and the transition to a clean energy economy address the needs of vulnerable residents of disadvantaged neighborhoods and frontline communities without inadvertently causing harm.

The participants developed a set of consensus principles for storage deployment that elevate the critical importance of community-led clean energy solutions. Together, these principles can help state policymakers focus on solutions that ensure that the growth of energy storage improves all communities, including environmental justice communities, communities of color, low income residents, tribal communities, and historically disadvantaged communities. Importantly, these principles are not meant to constrain organizations taking stronger positions on particular policies, regulatory proceedings, or project proposals.

As renewable energy capacity rises around the globe, markets are changing, creating opportunities for new businesses and technologies.

One of the primary beneficiaries of the tide of renewable energy is a battery storage industry whose global market volume will rise to $13.13 billion by 2023, buoyed by necessity and falling system prices.

That is the prediction made by market analysis company Globaldata in its Battery Energy Storage Market, Update 2019 – Global Market Size, Competitive Landscape and Key Country Analysis to 2023 report, which states the Asia and Pacific region (APAC), as well as Europe, the Middle East and Africa (EMEA), will be the most dominant battery storage markets up to 2023.

According to the analysts, the APAC region made up 45% of the world’s installed battery storage capacity last year. The region will continue on that trajectory, said Globaldata. In China, India, Japan, South Korea and the Philippines in particular, said the analysts, significant uptake of grid connected renewable electricity generation will necessitate frequency control in grid networks to improve resilience.

The EMEA region significantly increased its battery storage market share between 2013 and 2018, to a 26% slice of the world market worth $1.72 billion. The Globaldata report adds, the European market has robust demand for flexibility and will be EMEA’s driver for new storage capacity with Africa and the Middle East to follow suit once renewable energy deployment gains traction.

The Americas battery storage market was slightly larger than EMEA with a registered value of $1.97 billion last year, to make up around 28% of the global market. Chile, Canada, Brazil and the U.S. in particular saw rapid uptake of storage.

Globaldata analyst Bhavana Sri said: “The U.S. has been the largest [national] market for battery energy storage systems, both in terms of cumulative installed capacity and by market value, for projects installed up to 2018 and is likely to continue to lead the market at the country level. The U.S. market for battery energy storage is estimated to reach $2.96 billion in 2023, accounting for 23% of the global market.”

Washington — Having received the nod from the Federal Energy Regulatory Commission, New York’s grid operator is moving forward with a proposal to prepare its real-time market settlement rules for the expansion of wholesale market participation by energy storage resources.

New York currently has about 30 MW of energy storage capability, all located downstate, but its grid operator anticipates that figure growing to more than 1,000 MW by 2025 and nearly 4,000 MW by 2039.
FERC’s Order 841, issued last year, mandated tariff changes creating market participation rules that recognize the physical and operational characteristics of storage and accommodate its participation in the wholesale power markets. New York Independent System Operator in December filed a suite of tariff revisions (ER16-467) to comply with the order, and separately worked energy storage resources into a March 15 proposal (ER19-1332) to remove unnecessary complexity from its real-time market settlement rules.

NYISO has requested an effective date no earlier than May 1, 2020, for its Order 841 compliance filing, which remains under FERC review. But the commission Friday accepted the proposed real-time market settlement rule tweaks.

The changes, which will take effect May 15, clarify calculations regarding energy injections and withdrawals that are not scheduled in the day-ahead market, including deviations from day-ahead schedules. Such injections and withdrawals are subject to NYISO’s real-time market settlement often referred to as balancing market settlements.

The resulting balancing payments and charges address differences between scheduled and actual energy injections and withdrawals as well as differences between real-time and day-ahead energy schedules.

CONSOLIDATED TARIFF SECTIONS
FERC’s Friday sign-off clears the way for NYISO to consolidate tariff language addressing real-time market settlement for energy injections into one section and settlement for withdrawals in another section. The grid operator determined that differentiating between whether actual market activity exceeded or was less than day-ahead schedules was adding “unneeded complexity to the tariff rules.”

TORONTO–(BUSINESS WIRE)–Convergent Energy + Power (Convergent), the leading independent developer of energy storage solutions in North America, and Shell *, today announced a joint venture starting with 21 MWh of industrial battery storage systems at two Shell Canada Products facilities in Ontario. Convergent and Shell New Energies intend to collaborate on future projects for customers within and beyond Shell’s affiliated portfolio.

“Convergent is focused on building projects that save our customers real money while also increasing the overall sustainability and reliability of electricity,” says Convergent CEO Johannes Rittershausen. “We are proud to launch this joint venture with Shell to create value for a broader group of customers.”

By using the energy storage solutions developed and operated by Convergent, commercial and industrial customers can lower their energy bills by decreasing the amount of electricity their facilities consume during grid peak periods. For example, Convergent’s PEAK IQ™ dispatch algorithm is 25% more accurate at peak prediction than public market forecasts, which, coupled with the energy storage system, can save large commercial and industrial customers up to 40% on their electricity bills. The first two projects under the joint venture are currently in the construction phase at Shell Canada Products facilities in Brockville and Sarnia, Ontario.

“Convergent has a strong track record of delivering cost savings and resiliency services to large industrial customers,” says Eric Bradley, Global General Manager Connected Energy, Shell New Energies. “This energy storage offering complements the broader suite of solutions, including energy efficiency and energy management, that we already provide.”

Convergent is the largest operator of energy storage solutions in Ontario, with 26 MW in service, and Shell Energies North America provides comprehensive power services to industrial customers throughout North America, including Ontario. Under the partnership agreement, Convergent’s energy storage solutions will be offered to existing Shell Energy North America customers in Canada.

Massachusetts is a leader in the deployment of distributed energy storage in America, due to forward-thinking legislative approaches and other measures aimed at unlocking the full potential of the resource, analysts told Utility Dive.

The state, which is part of ISO New England (ISO-NE), recently became the first in the nation to allow behind-the-meter (BTM) energy storage to qualify for energy efficiency incentives. But the biggest boost to storage deployment in the state came when regulators decided to include storage resources in a new solar incentive program, Solar Massachusetts Renewable Target (SMART).

“Solar projects that participate under our SMART program are eligible to get an additional compensation rate if they pair with energy storage. You get more money if you pair with storage. The bigger the storage is and the longer duration it is, the more money you get,” Michael Judge, renewable energy division director of the state’s Department of Energy Resources (DOER), told Utility Dive.

The policy allowed Sunrun to bid into ISO-NE’s capacity market with 20 MW of aggregated BTM solar-plus-storage.

First of its kind
As a developer, Sunrun has reaped the benefits of Massachusetts’ aggressive push to expand energy storage deployment. The California-based renewable energy developer earlier this year set a new benchmark when ISO-NE accepted its bid for the 2022-2023 capacity market auction.

The success of Sunrun’s bid was a combination of strong state level policies and favorable wholesale market pathways, Christopher Rauscher, the company’s director for policy and storage market strategy, told Utility Dive.

“If we didn’t have that rock solid foundation for residential solar, we would not have been able to add on the storage in aggregate and fit into the market. That’s really what unlocked this at the state level,” he said. “The New England system operator, they have market access rules that are much more conducive to residential demand side resources than any other market in the country.”

Similar to Massachusetts, other ISO-NE markets, including Vermont, New Hampshire and Rhode Island have policies to encourage the development of residential solar and energy storage. Sunrun anticipates that the contract’s 20 MWs of capacity will be met with roughly 5,000 homes featuring onsite solar-plus-storage, which will be tied together through software to create a dispatchable resource for the system operator.
