Virginia governor Terry McAuliffe signed 11 bills earlier this week that promote solar and other renewable energy resources such as pumped hydro.

The bills include proposals for establishing a community solar pilot project, include energy storage in the mission of the state solar development authority and increase the size of clean energy projects eligible for permit from 100MW to 125MW.

The legislation indicated that the legislature is making a concerted effort to promote renewables and energy efficiency in the state; a move which was propounded by local utility Dominion Virginia Power – which recently has called for the integration of 5.2GW of new solar capacity over 25 years.

In this spirit, the state has increased clean energy investment from US$500 million to US$2 billion since 2014, with officials underscoring the associated job creation as an incentive for approving these bills. 

Key bills

Virginia is relatively demure when it comes to renewable energy, actually falling in rankings this year for installed capacity – going from 17th in 2016 to 20th this year – with 238.3MW of installed solar, according to the Solar Energy Industries Association (SEIA).

But things are starting to get moving, thanks to this legislative effort by the state.

“It is clear that Virginia is moving in the right direction, especially with the recent announcement of record growth in our solar industry, but there is still work to do,” governor McAuliffe said Monday.

“[The] bill signing highlights the commitment we have to reducing energy consumption and providing more sustainable energy options in the Commonwealth,” added secretary of Commerce and Trade, Todd Haymore.

One key measure, SB 1393, authorises community solar pilot programmes to be run by the Appalachian Power Company, Dominion, and the Electric Cooperatives. Each utility will develop its own territory-specific programme that allows citizens and businesses the ability to subscribe to receive electricity generated by a small centrally-located solar generation system.

HB 1565 develops green zones giving special taxing and zoning exemptions for energy efficient buildings, and HB 1760/SB 1418 secures a rate approval for pumped hydro storage projects in the south-western area of the state.

The terminology might seem diminutive, but there is no doubt that the future for microgrids is anything but small.

In fact, in future, microgrids themselves won’t necessarily be that small physically in their own right either. Misconceptions about the isolation of microgrids also abound.

They don’t have to work in full isolation, they may in fact be made up of several small grids and via the legacy grid, they may well be connected in the future to series of similar microgrids. It’s not easy to find a catch-all term that encompasses all of these characteristics. So with the objective of scaling up the benefits of microgrids to larger and larger systems, is the name misleading?

“Possibly, yes,” says Troy Miller, director of grid solutions at S&C Electric. “We’ve got some exciting projects in the pipeline that are much larger. People have used the term microgrid generically to mean a system, whatever the size, that can be separated from, islanded from. The overall larger grid is measured in GWs and TWs, microgrids can be tens or hundreds of MW. I haven’t heard a name for them as they get bigger but people have coined new terms for them as they got smaller, nano- grids and pico-grids.”

S&C played a key role in the development of an ambitious micro-grid project completed in 2015 for the Texas utility firm Oncor. The site is part of a large Oncor testing facility that had been operating with diesel back-up. The motivation for the project was two-fold, one financial and one strategic.

“They originally wanted to build a microgrid from the ground up, greenfield, with all new sources of generation. To save on some of the capex they decided to integrate the existing generation assets. So they hired S&C to create a dynamic microgrid to combine the sources they had on-site with some newer assets, a microturbine, some battery storage as well as PV,” explains Miller. “It was a fairly complex problem. They were looking to reduce the amount of energy they used and use the most energy efficient sources first, the PV, followed by the energy storage, followed by the microturbine and lastly the diesel, to reduce their need for additional generation. Then they were trying to match the critical loads with the available and existing generation.”

Mission statement

Santiago, Chile, Westborough, Massachusetts, USA and Tokyo, Japan (PRWEB) May 09, 2017

Competing under a demanding process against a robust group of other leading energy storage companies, NEC Chile was awarded and signed the contract with ENGIE Energía Chile last week. This project is the first smart energy project for NEC Chile and will be the first energy storage system which will be operated by the ENGIE group in the region.

“This energy storage project is the first step by ENGIE Energía Chile to establish a new energy storage business, in line with the change of the business strategy of the ENGIE group to invest less in traditional generating technologies and focus mainly on renewable energy. This project aims precisely in that direction and for its development we have chosen one of the most experienced companies in the world,” said Axel Leveque, general manager of ENGIE Energía Chile.

The energy storage system will be installed in the second half of 2017 in the city of Arica, in the north of Chile. The system will be designed to offer ancillary services such as spinning reserve and time-shifting, helping the integration of PV and wind projects. It will be connected to an existing substation. This will mark the third project in Chile for NEC Energy Solutions since 2009, which had under previous ownership installed 32 MW of grid energy storage solutions in the country.

In cooperation with NEC Energy Solutions, NEC Chile will provide a GSS® grid storage solution including containerized lithium ion batteries, power conversion system, and NEC Energy Solutions proprietary AEROS® controls system, as well as service and maintenance packages to ENGIE.

CAISO is moving forward with an initiative meant to ease the integration of distributed resources into its markets.

The main goal of the program: to make it easier for grid-connected resources such as rooftop solar, energy storage, plug-in electric vehicles and demand response to participate in the ISO’s market operations, creating more system flexibility and reducing carbon dioxide emissions.

“The number and diversity of these resources are growing and represent an increasingly important part of the resource mix,” CAISO said in its revised proposal.

On May 4, CAISO provided an update on phase two of its Energy Storage and DER initiative, which will propose changes that are due to be reviewed by the Energy Imbalance Market (EIM) Governing Body on July 13 and submitted to the ISO’s Board of Governors for approval during its July 26-27 meeting.

The proposals involve improving the accuracy of DR contributions through alternative energy usage baselines, distinguishing between charging energy and station power for storage resources, and developing a net benefits test for DR resources that participate in the EIM.

Expanded Baseline Options

According to CAISO, a majority of market participants support a set of baselines to assess the performance of proxy demand resources — DR aggregations of retail customers — that was developed by a stakeholder working group.

While the current “10-in-10” baseline methodology is considered accurate for many large commercial and industrial customers, stakeholders don’t think it is appropriate for all customer types, prompting the working group to propose additional baselines. Using the 10-in-10 methodology, the ISO calculates a baseline by examining the 45 days prior to a trade date and finding 10 “like” days in which no DR was required. The ISO then uses hourly average meter data to create a baseline representing a typical load profile, and the resource is paid for reducing usage below the baseline.

Under the new proposal, baselines for residential resources would be based on a four-day weather match that estimates what electricity use would have been in absence of DR dispatch under similar weather and on similar days, and using a control group of similar users.

Commercial baselines would be based on the 10-in-10 method with a 20% adjustment cap, an average of the previous five days and a control group. Baselines are adjusted using actual load data in the hours preceding a DR event to better reflect variables that might not be present in the historical data.

“Stakeholders who supported the proposal stated that the use of additional baselines for residential and commercial customers would improve the accuracy and reduce bias when compared to the 10-in-10 baseline,” CAISO said.

Mercedes-Benz is bringing energy storage to home and business owners in the United Kingdom.

Homeowners in the UK can have up to eight 2.5 kWh storage modules installed for a total of 20 kWh of back-up power. Commercial customers will have access to even more power.

The lithium-ion batteries are based on the same technology that’s gone into over 80,000 plug-in hybrid and all-electric Daimler vehicles since 2012.

Homes and commercial properties with their own solar power panels can store the surplus power without a loss, says Mercedes-Benz. Households will be able to increase consumption of that generated energy by as much as 65 percent.

Parent company Daimler started the energy storage division in 2015 soon after Tesla Energy was launched. BMW and Nissan have also started up energy storage businesses.

Users can bring in a customized pack of components for energy storage system. These include a photovoltaic system generating solar power, a battery inverter, an energy management system, the Mercedes-Benz energy storage unit, and the cost of installation.

The photo gallery below shows the range of storage size and capacity available to end users.

The German automaker’s energy storage unit is working with UK distributors including Alternergy, Innasol, and Wind & Sun. Other companies, such as Solar Frontier, can provide complete system installations. These types of stationary battery storage systems are often installed together with solar panels, Mercedes-Benz said.

Market demand for clean energy and storage is building up in the UK.

“There is tremendous interest in our energy storage units in the UK. We’re very pleased to be able to offer Mercedes-Benz Energy Storage Home to customers here,” said Marc Thomas, managing director of Mercedes-Benz Energy.

Mercedes-Benz Energy has its eyes set on two more growth markets beyond sales in the UK: large-scale industrial projects in the ‘primary reserve’ market; and the founding of Mercedes-Benz Energy Americas.

Grid integration of renewable energies, increased efficiency and durability of lithium-ion batteries, and the step towards megawatt output: The ees Award 2017 reflects the current developments in the industry. Finalists for the prestigious award have been selected from a wide range of international submissions. The winners will be announced at ees Europe, the continent’s largest and most visited exhibition for batteries and energy storage systems, at the Innovation and Application Forum on 31 May, 2017. The exhibition takes place parallel to Intersolar Europe, the world’s largest exhibition for the solar industry and its partners, from 31 May to 2June in Munich.

Over the last few years, the energy storage industry has boomed. Systems are becoming increasingly affordable – for example, lithium-ion storage systems were 15% cheaper in the second half of 2016 than the start of 2015 – making it increasingly attractive to invest in this technology. The development is being driven by numerous innovations which make batteries more powerful and more reliable. The ees Award has been honoring pioneering developments in the industry for four years.

Submission trends

The industry is clearly dominated by the topics of efficiency and durability, which is reflected in the submissions for the 2017 ees Award. The vast majority of projects submitted were in the area of lithium-ion technology, with a marked increase in high-voltage storage systems. Progress has been made in terms of energy density, capacity and lifespan. Easy-to-install modular storage systems are another hot topic. Self-configuring battery systems make design and installation easier and minimize potential sources of defect. And to boost functionality, there is a trend towards standardizing interfaces and data logs. Quality and safety also play an important role amongst this year’s submissions. The aim is to develop systems which can be used safely for longer, while minimizing operating expenses. Large-scale storage systems in the megawatt range are gaining a foothold in the market, thanks to the decreasing cost of lithium-ion batteries. These systems support the grid by providing balancing power and stabilizing frequency and voltage, and are used as an emergency power supply or mini-grids in combination with PV and wind energy installations. Lead battery systems are also being optimized, and are frequently used in off-grid applications. Here too, there is a trend towards modularity and reducing installation and operating costs. Standardized PV battery systems which are compatible with mini-grids can be scaled to any size, and thus make it possible to supply self-controlled and self-learning power in remote areas.

It’s the stuff of an action-hero movie: An accident threatens an unsuspecting metropolis. Electricity supplies face disruptions and millions are at risk of being without electricity as blackouts roll across the city. Faced with the prospect of escalating chaos, officials gather on the steps of government buildings and implore, “Who can help us?”

But let’s leave that cliffhanger for a moment, knowing that reality was not quite so—shall we say—Hollywood.

Even so, this movie-quality crisis is based in fact and has energy storage as its action hero. The increasingly mainstream zero-emission technology helped ease a real-life crisis that had all the makings of a major catastrophe.

Official records say that on 23 October 2015, a significant natural gas leak in well SS25 was detected at the Aliso Canyon natural gas storage facility in the San Fernando Valley north of Los Angeles. Repeated attempts by Southern California Gas Co., the owner, to “kill”—plug up—the well and stop the leak failed.

SoCalGas relies on Aliso Canyon to provide gas for core customers—homes and small businesses—as well as non-core customers, including hospitals, local governments, oil refineries, and 17 natural gas-fired power plants with a combined generating capacity of nearly 10,000 megawatts.

As part of a multi-part response to the crisis, the California Public Utilities Commission in May 2016 fast-tracked approval of 104.5 MW of battery-based energy storage systems within the service areas of Southern California Edison (SCE) and San Diego Gas & Electric (SCD&E).

Those utilities, along with the Los Angeles Department of Water and Power—the nation’s largest municipal utility—provide gas and electric service to most of southern California. By the end of February 2017, seven of eight fast-tracked Aliso Canyon–related energy storage projects were online, helping the region’s energy grid regain stability.

The significance of the Aliso Canyon energy storage deployment is “hard to overstate,” says Alex Morris, director of policy and regulatory affairs for the California Energy Storage Alliance, an advocacy group.
