Utilities are seeking new ways to respond to grid defection as the economics of solar-plus-storage make it easier for homeowners to disconnect.

A report called The Economics of Grid Defection, by the Rocky Mountain Institute (RMI), concludes that in territories such as Hawaii off-grid solar plus storage is already economically competitive with remaining on the electricity network.

Tens of millions of customers will defect in other areas such as California and New York as solar plus storage achieves grid parity by 2030, and possibly even 2020, the RMI predicts.

And grid defection is by no means a US-only phenomenon.

In many parts of Australia and Germany, for example, the business case for residential PV and storage is still far from convincing, but that has not stopped homeowners from installing systems for a whole host of other reasons.

San Francisco, USA-based Advanced Microgrid Solutions (AMS) is expanding into Texas as part of moves to grow its presence outside its core California market.

The company this month announced a USD$3.24m US Department of Energy grant-funded project with Pedernales Electric Cooperative (PEC), of central Texas, to investigate the use of storage with distributed solar generation.

The news came hot on the heels of another deal, with Texas Electric Cooperatives (TEC), to showcase a 200kWh AMS installation and offer energy storage systems at preferential rates to TEC’s member cooperatives.

“TEC is the co-op of co-ops,” said Manal Yamout, vice president of policy at AMS. “They have 75 co-op members, and what TEC does for them is bulk-buy poles and wires and now AMS batteries.”

The partnership is essentially a distribution deal that opens the door for AMS to sell batteries and services to consumer-owned electric cooperatives serving 2m homes and businesses in Texas, Oklahoma and New Mexico.

New York, USA-based Convergent Energy and Power is seeing the fruits of sticking to a pure-play developer model after building a 75MW, 200MWh project pipeline.

Johannes Rittershausen, Convergent’s CEO, told Energy Storage Report that behind this pipeline of projects in operation, being built or under contract there was “hundreds of megawatts … of deals we’re working on.”

Even though the company is currently focused on just two countries, the USA and Canada, its business has been doubling every year for the last couple of years.

In the next couple of years, said Rittershausen, “I could easily see a scenario where we could do better than that. We can barely keep up. It’s a great market to be in.”

The most recent addition to Convergent’s portfolio is the 7MW, 7MWh Sault Ste Marie plant in Ontario, Canada, being built to store wind and solar energy under a three-year contract with the Independent Electricity System Operator (IESO).

Alevo, a Swiss battery maker with operations in Concord, North Carolina, USA, has confirmed the first commercial delivery of its sulphur-based lithium-ion GridBank product.

The company is due to install six 2MW/1MWh GridBank units this month across three sites in Hagerstown, Maryland, to provide frequency regulation and other ancillary services to the PJM Interconnection Market.

Speaking to Energy Storage Report during European Utility Week last year, Alevo officials confirmed that two other projects were already “grid connected.”

The implication is that these two projects, a 8MW/4MWh deployment Lewes, Delaware, which was announced in March 2016, and a 10MW, 3MWh project in Georgetown, Texas, are non-commercial pilots.

According to the Charlotte Business Journal: “The company has taken longer than initially expected to get to commercial production of the battery and its control systems.

The value that led Enel to buy Demand Energy

By Jason Deign

Enel’s buyout of US project developer Demand Energy last week was largely down to a secret ingredient that has been cooking for several years.

While Washington State-based Demand Energy has a decent portfolio of projects in New York and closed last year with a microgrid deal in Costa Rica, the real lure for Enel is understood to have been its software platform, DEN.OS.

DEN.OS, which stands for ‘Distributed Energy Network Optimization System’, is a cloud-based platform for integrating energy storage and distributed generation that Demand Energy has perfected over the last eight years.

A critical early challenge facing the company was how to adapt its software to work in New York, a market characterised by longer-duration storage applications.

The market was of interest because the state’s Reforming the Energy Vision plan was creating new opportunities for storage to complement distributed generation in reducing demand, shifting load and adding resiliency.

The rise of electric vehicles: what can it lead to?

GUEST POST by Rhys Walker, cost estimator, Glenmore Investments

According to the latest predictions, the cost of electric vehicles is likely to be the same as their internal-combustion counterparts by 2022, while by 2040 this price is predicted to become even lower.

Skeptics would say that predictions should not be taken too seriously as they are always to some extent based on merely subjective opinions. This is absolutely right, just like is the fact that electric car sales continue to increase.

Statistics say that global sales increased by approximately 80% in 2015 compared to 2014, from 315,519 to 565,668, while by the end of 2016 the number of electric cars on the world’s roads is expected to exceed 2 million.

By 2040, for instance, electric vehicles would account for 35% of all new vehicle sales. What this implies is that even if some years or numbers in such sort of predictions may be inaccurate, the tendency of sales growth is definitely strong and cannot be doubted.

Energy storage systems developer Demand Energy and Latin America microgrid pioneer Rio Grande Renewables this week announced a record-breaking project in Costa Rica.

The two companies have commissioned a battery storage-plus-solar-PV microgrid at Establishment Labs, a Costa Rican medical manufacturing plant, said Demand Energy in a press release.

The microgrid is said to be the largest in Central America and includes a 500kW, 1MWh lithium-ion battery connected to 276kW of solar PV.

The system is designed to provide multiple on-site and grid-assisting services, including peak demand reduction, solar variability smoothing and backup power for critical loads in the event of an outage.

It is controlled by Demand Energy’s Distributed Energy Network Operating System (DEN.OS™), which optimises how energy storage, distributed generation and other distributed energy resources interact and perform.

Finland’s nascent grid-scale battery market is set to expand rapidly in the coming years, according to Landis+Gyr’s Northern Europe CEO Ari Tolonen.

He told Energy Storage Report his company was pursuing four other energy storage projects in Finland after completing the largest battery plant in the Nordic countries earlier this year.

Up to 4MW of battery storage could be installed across the country “very soon,” he said. “I believe we will see three or four cases a year. I expect to see this kind of system everywhere.”

In August, Landis+Gyr commissioned a 1.2MW, 600kWh battery system for Helen Electricity, a distribution system operator covering the Helsinki area of Finland.

The €2m Helen storage facility was built alongside Finland’s largest solar plant, a 340kW array in Suvilahti, and will also serve an 850kW PV project being built at nearby Kivikko.
