STELLA Futura

What STELLA Futura does

Stella Futura is a Stockholm-based developer and financier of battery energy storage systems (BESS) serving grid operators, industrial facilities, commercial properties, and energy producers across the Nordic region. The company designs, finances, installs, and operates behind-the-meter large-scale storage systems (0.5 MW and above) using LFP battery technology, BMS, and inverters sourced from European suppliers. Its core architectural concept, service stacking, allows a single battery installation to simultaneously deliver peak shaving, load shifting, backup power, and ancillary services such as FCR and FFR into the Svenska Kraftnät balancing market.

Stella Futura operates three commercial modules: Project (full-service delivery including feasibility, design, installation, commissioning, and O&M), Product (battery sale to customers with prepared sites), and Battery-as-a-Service (BaaS), under which Stella finances, owns, and operates the asset while the customer shares in revenues and savings via a lease arrangement. Reference projects include a 15 MW / 18.72 MWh system for Härjeåns, a 9 MW / 11.32 MWh system for a utility client in Vaggeryd, a 750 kW / 1.44 MWh backup system for an automated warehouse, a 1 MW / 1.1 MWh FFR system integrated with a hydropower plant, and a 1.2 MW / 1.44 MWh ancillary-services installation. The company states 50+ completed projects and 50+ MW under development.

Go-to-market is enterprise field sales targeting large C&I and utility buyers in the Nordics, supported by thought-leadership content through the Stella Battery Academy, the Knowledge Bank, and the Futurapodden podcast. In January 2025 the company entered strategic partnerships with Elinor Batteries (securing Nordic LFP supply and targeting 5 GWh by 2030) and Polarium (reseller arrangement targeting 100 MW in 18 months), and on June 4, 2025 Polarium announced the acquisition of Stella Futura. The company's original 2018 Africa-focused operations were spun off into the sister company Infra Futura in 2023.

Core offering

Stella Futura develops, integrates, and finances large-scale battery energy storage system (BESS) solutions of 0.5 MW or larger for grid operators, industrial facilities, commercial properties, and energy producers in the Nordic region. The company delivers battery systems built around European LFP battery technology with proprietary service stacking, providing peak shaving, load shifting, backup power, and ancillary grid services (FCR, FFR), offered through three commercial models: full Project delivery, Product purchase, and Battery-as-a-Service (BaaS) financing.

Product overview

Stella Futura offers a comprehensive BESS (Battery Energy Storage Systems) portfolio consisting of three service modules: Project (full-service battery system purchase with design and installation), Product (battery purchase for customers with prepared sites), and BaaS (Battery-as-a-Service with full financing). Their core offering targets large-scale storage systems (0.5 MW+) serving grid operators, industries, commercial properties, and energy producers. They combine European battery technology with flexible financing models and provide services including load shifting, peak shaving, ancillary services, and backup power. Knowledge dissemination through Futurapodden podcast and Stella Battery Academy complements their technical offerings.
