Norway Grants „Green ICT“ program

This project aims to reduce energy sector carbon intensity while increasing the energy system's efficiency.

About the Project

Norway Grants Green ICT program gives Fusebox and Pixii the unique opportunity to collaborate on a renewable energy field project.

The innovation of this project is to combine demand-side flexibility (demand response) with energy storage systems (modular batteries) into a hybrid solution.

While existing infrastructure was built to support centralised electricity generation, we combine Fusebox’s competence in demand response with Pixii’s energy storage expertise to enable next-generation energy infrastructure. The project allows real-time communication between electricity consumers, energy storage, and energy systems to maximise the use of renewables. It also helps to solve the issues related to variable generation. We offer an integrated flexibility system for a cost-effective, green, and resilient grid globally.

Implementation Period

1st of June 2021-1st of June 2023

 

Progress

1st stage. First, we are mapping suitable locations for energy storage units. We install the energy storage units and other necessary hardware for different purposes in different places. We develop operational capability and connectivity between energy storage units and Fusebox virtual power plant platform and run field testing.

  • During the first stage Fusebox has mapped 3 potential energy storage locations. Two battery energy storage units are located in Estonia and one is in Finland. These sites include a lot of potential to benefit from the value stacking of energy storage. Batteries are adding value to EV chargers and distributed renewable generation such as solar and hydro.
  •  First battery installation was completed in January 2022. 100 kW/kWh battery was installed in Jägala hydropower plant in Estonia. Read more:

  • Active testing since February 2022.

2nd stage. In the second stage, we focus on market integration and piloting. We pilot new products and ancillary services, such as frequency and voltage control in the electricity grid. We will test Pixii energy storage systems and Fusebox virtual power plant platform functions according to the local market rules and technical requirements. Accordingly, we will develop additional functions on the Fusebox platform and test them with the Pixii energy storage system.

  • Fusebox has tested Pixii energy storage systems on various markets such as Finland and Estonia.
  • Fusebox has built an integration with Finnish energy market and transmission system operator Fingrid according to local market rules and technical requirements. As a result Fusebox could provide reserve power market services in Finland combining batteries with local consumption, local generation, EV chargers, and demand response.
  • Battery capacity in Finland is 150 kW/325 kWh. The battery system is located in Laappenranta city and is connected to IsoKristiina shopping mall.

3rd stage. Based on our measuring and trading data, new complex functionalities are in focus. The aim is to maximise the utilisation of EV-s and renewables in combination with energy storage systems. Our hybrid solution can provide flexibility services in two different ways; locally it can increase the EV charging power capacity and charging stations in densely populated or remote locations whilst also storing excess solar power. On the other hand, nationally, it supports electricity grid stability.

4th stage. The focus is on user experience for usability and future expansion. This stage includes standardisation and optimisation of developed functions. We will fix software bugs. We are analysing the results and making conclusions. Both parties can provide several new services and products to different markets. Services we have developed together are following the local market regulations.
