Thermal energy storage developer Ice Energy is gearing up to increase sales of a product that has the potential to end California’s famous ‘duck curve’.

The Southern California Public Power Authority (SCPPA) has already announced plans to buy up to 100 of Ice Energy’s Ice Bear 20 residential cooling systems, which completed testing about a month ago.

The 20 ton-hour systems use energy when there is excess production, for example at night, to create ice that is then used for cooling during peak electricity consumption periods, such as evenings.

“At 9.6kW per Ice Bear 20, the order will potentially add nearly 1MW of new energy storage and peak demand reduction capacity to the SCPPA network, saving energy, improving efficiency and reducing emissions,” said Ice Energy.

The deal marks Ice Energy’s debut in the residential energy storage market, a move the company unveiled in Energy Storage Report last year, and follows growing utility interest in using Ice Bears for demand response.

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.

The year 2016 will probably be remembered as the point at which energy storage began to take off in earnest.

Projects came thick and fast as interest in storage extended quickly beyond early hotspots such as California and Germany.

We saw grid-scale storage playing a starring role in the UK’s frequency response market, while battery makers jostled for position in an increasingly buoyant Australian consumer market. And that was just a couple of examples.

Almost every major energy market in Asia, Europe and North America had a storage story to tell. But which were the ones that caught your eye? Here’s a rundown of our most popular headlines from 2016.

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 sees growing role for energy storage

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.

Why you should aim for an open business model

Delegates at next year's Energy Storage Europe Conference will hear a plea for open business models (Pic: Energy Storage Europe 2016).

Delegates at next year’s Energy Storage Europe Conference will hear a plea for open business models (Pic: Energy Storage Europe 2016).

Energy storage developers and asset owners should aim to be technologically neutral to make the most of global markets, experts will hear next year.

Florian Mayr, partner and storage expert of management consultancy Apricum, is due to make the case for technologically open business models at the Energy Storage Europe Conference 2017 in Düsseldorf, Germany.

These models can benefit most from the growth of international storage markets as flexibility becomes a key factor for success in the industry, he claims.

“Today storage markets are still comparatively small and characterised by individual, often geographically determined application cases,” he said.
