ABB microgrid to bring power reliability to Alaska community

13.02.2017

A microgrid combining battery and flywheel based storage technologies will be installed in Anchorage. The small scale project aims to identify technologies that will enable the integration of more renewables.

ABB’s modular and containerized microgrid solution PowerStore will blend the complementary capabilities of the two storage technologies used. The flywheel will facilitate the integration of fluctuating wind power and the battery will be used for long-term storage. It has a capacity of 500 kWh with a maximum performance of 2 MW.

The microgrid aims to identify technologies that will enable the integration of more renewables, including wind power from a 17 MW wind farm on Fire Island, located about 4 km off the coast of Anchorage, which will work in concert with the innovative storage solution. “This innovative solution shows how energy storage technology can boost renewable energy penetration in Alaska and have far reaching implications for new renewable projects on the Railbelt as well as in smaller Alaskan communities,” said Paul Risse, Senior Vice President, Power Supply at Chugach Electric Association, Inc., the company that initiated the the project.

The microgrid will be monitored by ABB’s the Microgrid Plus control system to ensure proper loading share between the technologies. The system is also equipped for remote service and maintenance.

ABB is a renowned company in the field of microgrid technology. It has around 40 installations all over the world under its belt.

TrinaBEST announced today that it has been awarded to design and construct a hybrid energy storage system in Nouakchott, Mauritania. This project is developed and operated by Damane Assurances Company. The project which encompasses 40kW solar system, 415kVA diesel generator system and 320 kWh energy storage system, is expected to be completed by the end of 2016. When completed, it will be one of the largest Microgrid energy storage projects in Mauritania.

Younicos has signed an agreement with Kodiak Electric Association (KEA) in Alaska to design, install and commission an upgraded 3 MW battery-based energy storage system on Kodiak Island that will replace a system that was installed by the company in 2012. The project is expected to be complete by mid-August 2017, in time to support increased seasonal levels of wind power on the island.

TrinaBESS announced today that the company will introduce its large-scale Energy Storage Solution ‘TrinaMega’ for German Market at Energy Storage Europe 2017, held in Dusseldorf on March 14th - 16th. The event, which has always been influential to German large-scale Energy Storage market, affords TrinaBESS a great opportunity to introduce its new Energy Storage Solution. TrinaMega is a modular design of thousands of lithium-ion battery cells, integrated and controlled by advanced software giving a future-proof alternative to traditional methods by assisting transmission, generation and distribution networks.

After a full year of construction, the M5BAT modular large-scale battery storage system was put into operation in Aachen today. Prof. Dirk Uwe Sauer of the Institute for Power Generation and Storage Systems (PGS) at RWTH Aachen University, director of the project and M5BAT operations, said regarding the significance of the project for energy research: "From day one, we have intensely and individually monitored more than 25,000 battery cells in six strings of different lithium-ion battery technologies and four strings of different lead batteries. This will allow us to gather valuable information on aging, reliability, and service life. At the same time, we want to use intelligent battery management to show how overall operations can be optimized with a hybrid system using different technologies."
