Imergy Flow Batteries Installed at Trojane Restaurant, Part of AlpStore Energy Storage Strategy Development for Europe's Alpine Region

Energy Storage System Will Support the Restaurant's Solar Photovoltaic System, Which Provides It With the Power It Needs to Cook Its Famous Donuts

FREMONT, CA--(Marketwired - Jan 14, 2015) - Imergy Power Systems, a pioneer in advanced energy storage systems, today announced that Metronik Energija has installed two of Imergy's ESP4 series vanadium-based flow batteries at Trojane, a restaurant located in the Slovenian Alps.

Although famed across Slovenia for its donuts, the restaurant has already pioneered a number of advanced energy infrastructures for self sufficiency, including a 49 kilowatt (kw) photovoltaic solar power system, a 30 kw combined heat and power (CHP) system, and an electric vehicle (EV) charging station.

The energy storage project, sponsored by the Slovenian Utility Elektro Ljubljana and supported by the Business Suport Center Kranj, is designed to demonstrate how Imergy's flow batteries manage multiple applications, such as renewable energy system integration, peak demand reduction, backup power and EV charging. Energy storage systems that can support multiple applications like these deliver a higher return on investment (ROI) than systems that can only be used for a single application.

The project is part of the European AlpStore program, with partners from seven countries tasked with developing a long-term energy storage strategy for the Alpine regions. It will be evaluated by Elektro Ljubljana and will establish how energy storage systems incorporating vanadium-based flow batteries manage the intermittent nature of renewable energy sources. For example, the system will be used for solar firming with the PV solar power system at the restaurant, smoothing out the system's jagged solar power production in order to provide consistent power throughout the day. Flow-batteries are well-suited for solar firming and other renewable integration applications like these, as they can be charged and recharged an infinite number of times with little to no degradation in performance.

The evaluation period for the project will take two years, at which point an optimal function mix for this particular location will be set up and continuous operation will start.

The market for energy storage is growing rapidly. Worldwide revenue from energy storage for the grid and ancillary services is expected to grow from $675 million annually in 2014 to $15.6 billion in 2024, according to a report from Navigant Research.

"Trojane is well known for its advanced energy infrastructure for Renewables," said Dr Jurij Curk, of Metronik Energija. "The new Imergy flow-batteries will further strengthen our reputation, and help us demonstrate how renewable and other advanced energy technologies can provide the Alps with clean, affordable and reliable energy."

"This project reflects the increasing demand for energy storage systems that can perform multiple applications," said Tom Tipple, Imergy Power Systems Regional VP, EMEA. "By combining affordability with flexibility, Imergy's vanadium-based flow batteries deliver the price and performance needed for successful multi-use energy storage projects."
