Case Studies

  • Intelligence for Europe's Biggest Storage Project: Leighton Buzzard Battery Park (UK)

    This Smarter Network Storage (SNS) project aims to carry out a range of technical and commercial innovations to tackle the challenges associated with the low-carbon transition and facilitate the economic adoption of storage. It is differentiated from other LCNF electrical storage projects by its demonstration of storage across multiple parts of the electricity system, outside the boundaries of the distribution network.

  • Long-Duration Energy Storage on a Grid Scale: Highview Power Storage LAES

    Liquid Air Energy Storage (LAES) is sometimes referred to as Cryogenic Energy Storage (CES). The word “cryogenic” refers to a gas in a liquid state at very low temperatures. The working fluid is Liquefied Air or Liquid Nitrogen (78% of air). The systems share similar performance characteristics to pumped hydro and can harness industrial low-grade waste heat/waste cold from co-located processes, converting it to power. Size range extends from around 5MW/15MWh to >50MW/250MWh and with capacity and energy being de-coupled, the systems are very well suited to long duration applications.

  • Making Batteries a Business: Schwerin Battery Park

    gas nationally, it also operates a regional distribution grid in western Mecklenburg, northern Brandenburg and Lower Saxony through its subsidiary WEMAG Netz GmbH. WEMAGs’ wind-swept grid already has an installed renewable generation capacity of more than 800 megawatt (MW). In 2014 these assets generated more than 100 percent of the energy volume distributed to consumers in the 8,600 km² grid area.

  • 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.
