The aim of the project was to test new technologies, visualize the power output from a energy storage and experiment with new business models. The goal was a pilot plant where Falbygdens Energi has the ability to test, evaluate the technology and benefits of a local energy storage.

The project was implemented between 2011-03-22 and 2012-09-30

Test and evaluation of Energy storage

•Functions tests •Applications test •Business models

The goal is to test and evaluate an existing energy storage plague spirit in a local power grid, and to evaluate the role of energy storage in the size of 100 kWh may have in the future regarding function, applications and possible business models. The project will continue to 2014-12-31.

Energy storage connected to the wind power

The goal of the study is that the report will serve as an instruction and as a basis for a technical specification and can be used for a possible purchase of an energy store.

The project was implemented between 2011-11-01 and 2012-09-30.

Business models Energy Hub

http://www.ferroamp.com/energyhub/benefits-for-consumers

The purpose of the study is to investigate and evaluate new business models for energihuben, solar cells and energy storage. The local energy store is located directly adjacent to the consumer's installation. The business model will be the basis for getting the product to market. The goal is to find the business model that ties together the various new benefits with the product, where all partners supplier / customer / utility companies is winner and an intermediate goal is to identify and quantify the various new benefits that are the product of electric utilities, consumers and the environment.

The project will continue to 2013-12-31.

The first battery storage in Sweden. Case studies, possibilities and outcomes.

Conclusions

• Peak shaving/load shifting, Reactive power compensation, Power quality improvement

• Provides additional wind power in the grid • Applications (Increased hosting capacity, reduced cost, peak

reduction, reduced losses and prevention power interruption) • More profitable for a supplier than the network owner • Resonance problem (E-STATCOM)
