Case Studies

  • Participating in New Markets Through Innovative Storage Solutions: Younicos Battery Park

    In 2013, a major solar farm was installed in Texas. OCI Solar Power decided to look at incorporating energy storage into the mix, and turned to Younicos to launch its first energy storage initiative. The customer wanted to install the storage system alongside its solar farm, taking advantage of existing equipment and interconnection facilities. To preserve the versatility of the system, it was important to select a chemistry that could reliably participate in the markets for energy storage today, namely Fast-Frequency-Regulation-Service (FRRS). The team selected the LG Chem JP1 batteries.

  • Peak Shaving and Demand Charge Avoidance: Prudent Energy Vanadium Redox Battery Energy Storage System (VRB-ESS®)

    Gills Onions operates one of the largest, most innovative and sustainable fresh-cut onion processing plants in the world. Its Advanced Energy Recovery System (AERS) that went into operation in July 2009 converts all of the plant’s daily onion waste into a combination of renewable energy and cattle feed. The result is increased energy independence, elimination of a significant waste stream, reduced operational costs and a smaller carbon footprint.

  • Peak Shaving to Reduce Energy Costs: EaglePicher Power Pyramid™ Hybrid Battery

    The Power Pyramid ™ system provides seamless power to the load via multiple input sources. In this demonstration project, the input sources will include 10 kW wind turbine, 20 kW solar comprised of multiple solar panels and multi-tier battery storage comprised of multiple electro-chemistries.

  • Providing 100% Renewable Power to Large Residence on Protected Kona Coast

    In 2014, Aquion Energy completed installation of a 1 MWh battery system as part of an off-grid solar microgrid at Bakken Hale on the Island of Hawaii. Bakken Hale, a private residential estate, is located along the environmentally sensitive Kona Coast and cannot be connected to the grid. The Aquion battery system stores energy generated from a large on-site solar installation and enables Bakken Hale to operate entirely from self-generated solar power.

  • S&C Electric Company PureWave® Storage Management System Helps Reduce the NOx Emissions on Catalina Island, California

    Catalina Island—a historic landmark 22 miles off the coast of Long Beach, California—has a population of approximately 3,700 people. There’s no utility tie to the mainland. The island microgrid has a peak load of 5 MW which is served by Southern California Edison (SCE) through a combination of six diesel generators and 1.4 MW of micro-turbines. The diesel generators were deemed to be high emitters of mono-nitrogen oxide (NOx) gases by the South Coast Air Quality Management District. To mitigate these smog causing emissions, SCE installed emissions control systems which convert the gases into water. But the catalyst for this conversion is only effective at a specific temperature range, which is reached when the generators are run above 80% load. SCE needed a solution that would allow the generators to run more efficiently, and thus reduce NOx emissions on the island.

  • S&C Electric Company: Canada’s First Utility-Scale Energy Storage System Islands Remote Town During Outages

    S&C’s solution includes a 1-MW NGK sodium-sulfur (NaS) battery and an S&C PureWave® Storage Management System (SMS), which controls battery charging and discharging. It also includes S&C’s IntelliRupter® PulseCloser for fault detection, S&C’s System VI™ Switchgear, and S&C’s IntelliTeam® SG Automatic Restoration System for peak shaving and transitions between the battery and grid. S&C SpeedNet™ Radios provide fast, two-way communication to help speed restoration.

  • S&C Electric Company: First Wind Energy Storage Application in the U.S.

    Xcel Energy—a major wind energy supplier—wanted to maximize the value of the renewable energy generated by the turbines at their Minwind Energy wind farm, in Beaver Creek, Minnesota. Part of Xcel Energy’s Smart Grid strategy involves testing emerging technologies and energy storage devices, which they believe are a key to expanding the use of renewable energy. To this end, they contracted with S&C to furnish and install an S&C Smart Grid Storage Management System.

  • S&C Electric Company: PureWave® Storage Management System Fortifies California Jail’s Microgrid

    S&C engineered and commissioned a highly reliable energy storage solution. They supplied and integrated a 2-MW PureWave® Storage Management System (SMS) into the jail’s microgrid. Originally engineered by S&C for a sodiumsulfur (NaS) battery, the system was re-engineered for a 2-MW/4-MWh lithium-ion battery by S&C’s p oject team, which coordinated with both battery suppliers to ensure proper operation of the system. S&C provided engineering services and project management for the PureWave SMS and battery installation.

  • S&C’s Energy Storage Solution Improves Power Quality in Australia’s Outback

    Electricity utility Ergon Energy was looking to improve power quality on its Single Wire Earth Return (SWER) lines, which were developed a century ago to bring power to remote parts of Australia and New Zealand. A single SWER line may stretch for hundreds of kilometers, with distribution transformers positioned at intervals along its length. The primary purpose of the SWER schemes was to accommodate basic domestic and farm loads.

  • Saft Li-ion batteries helps Gran Canaria’s STORE project integrate renewables

    Installing Saft’s energy storage system (ESS) on Gran Canaria is an ideal opportunity to evaluate the technical and economic viability of innovative solutions by making reserves of energy available in isolated locations, distribution substations and for energy arbitrage. Endesa, part of the Enel Group and Spain’s largest utility, operates two, large thermal power plants, as well as the transmission and distribution network on the island of Gran Canaria.
