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 Reportlast year, and follows growing utility interest in using Ice Bears for demand response. Read more →

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. Read more →

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). Read more →

Saltwater battery manufacturer Aquion Energy is aiming to cut the price of its batteries by up to 50% within a decade, a company executive confirmed.
Newly named chief commercial officer Tim Poor said it was “very reasonable” to expect a 25% to 50% cut in costs once current manufacturing facilities reached full scale, which would happen within “single-digit years.”
Aquion currently has manufacturing capacity for 200MWh of batteries a year, based on a single production line. But the company’s factory has space for four more lines, allowing for up to 1GWh of capacity to be produced a year.
Poor said the company was planning to double production in the fourth quarter of this year. Aquion has so far shipped 20MWh of storage to about 200 customers, with 50% of products going for export, he said.
Historically, though, Aquion has tended to attract attention for its fundraising escapades rather than its business growth. Read more →

Energy Storage Report understands the offering is not so much an integrated product as a concept aimed at raising awareness of the efficiency of cold storage over batteries.
Using cold storage with grid power can improve the efficiency of energy use by up to 34%, Viking Cold claimed.
Combined with solar, it could cut ongoing energy costs much further while providing a quicker return on investment (ROI) than batteries, the company said.
“We aim for a three-year payback,” said James Bell, president and CEO. “Our return on investment is based on energy savings. The bigger the facility, the bigger the savings. It can be tens of thousands of dollars a year.” Read more →
The Intersolar North America 2013 conference has now been and gone, leaving in its wake some fascinating comments, observations and presentations on energy storage. One recurring theme this year was an increasing interest in combining photovoltaic (PV) technology with battery-based storage, in order to take advantage of excess solar power and bring down the overall unit cost of energy produced.

The Wind Energy Institute of Canada has announced a supply agreement with S&C Electric Canada for a battery energy storage system (BESS) at Prince Edward Island. The BESS will be delivered in September and is expected to be operational by autumn. The BESS is composed of a power conversion system supplied by S&C and battery modules supplied by GE.
The batteries are sodium nickel chloride Durathon modules and represent the first such project for GE Energy Storage in Canada.
Officially launched with 70 founding members, the International Battery and Energy Storage Alliance (IBESA) states its mission is to “promote a path of cooperation and mutual support in achieving proactive solutions between all sectors within the photovoltaic (PV) power generation, battery storage and the smart grid technology value chain.”
The two men behind the new association are Bryan Ekus, managing director of the International PV Equipment Association, and Markus Hoehner, head of the Hoehner Research & Consulting Group.
Aimed at promoting networking and professional resources for “all those who produce and support solar, battery and energy services,” the IBESA costs €3,000 per year to join. We wish them every success and hope they will add to the development and adoption of energy storage.
