NorthStar will work with City Utilities of Springfield, Missouri, to deploy an energy storage system to evaluate how the city's energy supply can be made more efficient and sustainable. The demonstration will use NorthStar BLUE+ batteries monitored by remote management software.

ESS represents an emerging industry with a potential worldwide capacity of multiple gigawatt hours, Sweden-based NorthStar says.

The need for utilities to reduce peak power demand on generation, transmission and distribution systems has created a need for battery storage to fill reliability gaps and cut peak costs. Utilities strive to optimize transmission and distribution of the electric grid, among other objectives.

"The ESS market is expected to grow to $200-400 billion by 2040 and represents a significant growth opportunity for NorthStar," says NorthStar's CEO Hans Lidén.

The energy storage solution in Springfield will be deployed next to an electrical substation located southwest of Springfield. The project enables City Utilities to investigate the possibility of a utility scale battery storage system.

NorthStar's technology uses a thin plate lead carbon (TPLC) battery.

NorthStar ACE is an integrated remote monitoring system that combines Bluetooth communication with an Internet of Things (IoT) concept. The cloud service is built to aggregate and display data on a system level, but still only require a few clicks to display detailed data for a single battery. The system enables full control of the energy storage from anywhere at any time, which improves operation significantly.

The joint ESS project will be deployed in September 2017.
