STELLA Futura AB is currently planning a fully commercial flexibility project in Hammarby Sjöstad in Stockholm. The initiator and driving force in this innovation work is the board of Sjöstadens Västra Sopsug Samfällighetsförening. The stationary vacuum system is installed by Envac. It will now be equipped with a roof-mounted photovoltaic system equipped with a market-leading stationary battery system (BESS), to cut the high power peaks created by the use of the vacuum cleaner. At night, the community is offered opportunities for income from the Nordic flexibility market.


The project is a major breakthrough for the entire flexibility market and the business case shows a saving of over SEK 90,000 per year with a return on invested capital for the customer of over 12.4% annually!
The plant’s electricity use profile means that a battery system is ideally suited for cutting power peaks throughout the year and operating in the frequency regulation market at night. The assignment is completely commercial and is not dependent on investment support.


STELLA Futura is a new player in the Swedish energy and flexibility market. The company was chosen as the supplier on the basis of strong references, its competence and exceptional technical competence, in combination with the company’s Energy as a Service services (EaaS). In addition to solar cells and a BESS, this assignment includes software that aggregates a number of installed batteries in the frequency control market, such as the FCR.
The BESS that STELLA offers consists of a lithium-ion battery (NMC) with a prismatic battery cell with maximum safety. In addition, we deliver a unique control and optimization system that the company is the only one to offer in the Swedish energy and flexibility market.


During the summer of 2021, the facility will be taken into use. Afterwards, site visits will be arranged to showcase the energy system of the future and how an energy warehouse from now on is both economically and technically extremely profitable and efficient for operating economy through a unique integration solution and a market-leading EaaS solution.
