About Flower

Flower Infrastructure Technologies AB — energy tech company founded 2020 by John Diklev (CEO), Stockholm-based. Published legal entity: Flower Infrastructure Technologies MidCo AB (publ), a wholly owned subsidiary subject to EU Market Abuse Regulation. 130–140+ employees (as of April/May 2026). Financial backing is stated inconsistently across the source press releases themselves: >€160 million (Mar-2026 trading update, published 2026-04-29) vs. >€150 million (Saarland and Hamburg BESS releases, published 2026-04-30 and 2026-04-28) — likely just varying PR boilerplate rather than a real change, but the two figures aren’t reconcilable from these sources. Self-described “Nordic market leader in energy asset optimization and trading.”

Swedish BESS portfolio

Named BESS sites:

• Grums (10 MW) — Värmland, developed by Ellevio Energy Solutions, optimized by Flower since 2023; operational summer 2022; one of Sweden’s first commercial grid-scale BESS; originally developed for Svk FCR markets
• Kungälv (15 MW) — Flower’s first internally developed battery park in Sweden
• Sköldinge (4 MW) — acquired from asset portfolio, acquired/operational ~2024
• Bredhälla (42.5 MW) — Flower-operated battery park

As of April/May 2026: 4 operational sites, 63 MW total + 3 internally developed projects “to be operational by 2026” (70 MW additional) → ~133 MW Sweden total by end 2026.

The Grums BESS demonstrated grid value on 10 June 2024 when a Forsmark nuclear reactor temporarily tripped, creating a large frequency disruption — the battery stabilized the grid by releasing stored energy at the critical moment.

Ellevio Energy Solutions relationship: Ellevio Energy Solutions is the commercial/project development arm of the Ellevio group (distinct from the regulated DSO Ellevio AB). Ellevio Energy Solutions and Flower have developed three BESS projects together.

March 2026 trading performance

Published as a press release (MAR-regulated), covering Flower’s full BESS portfolio across SE2, SE3, SE4:

Capacity markets (FCR-N, FCR-D, FFR etc.) are overwhelmingly the dominant revenue source. At 0.8 daily cycles, the battery is used for frequency regulation more than for energy arbitrage — consistent with the FCR bid-and-hold model.

DER aggregation (April 2026 expansion)

Flower announced expansion from large BESS into distributed energy resources via cloud-based API optimization — no additional hardware required. First integration: Polarium HomeBattery (Swedish BESS manufacturer, API-linked). Partner ecosystem:

• Flexecharge — EV charging infrastructure management
• Markedroid — smart home energy management
• Emulate — smart home energy management
• Rebel — electricity retailer (Sweden)

Assets in pipeline for integration: EV chargers, heat pumps, C&I batteries.

Flower Hub (residential service, August 2024)

Residential battery optimization service:

• Hardware: one plug-and-play device (described as “iPhone-sized”) installed on same network as home battery
• Web portal with interfaces for distributors, installers, and end customers
• Revenue model: per installed capacity per month, index updated quarterly to follow market prices
• Launch distributors: Senergia and KP Energy
• TSO (Svk) pre-qualification for home batteries technically approved

PPA innovation

April 2025: Flower signed a long-term physical pay-as-produced PPA with Locus Energy (SEB Nordic Energy portfolio company) for 180 GWh/year from 11 onshore wind farms across SE2, SE3, SE4. Largest single farm: 65 GWh/year. Flower manages profile risk using its BESS portfolio and AI platform. Framed as a precursor to “next-gen PPAs” where the offtaker (Flower) manages profile risk, making PPAs more scalable and affordable for wind/solar producers than baseload or pay-as-produced structures.

European BESS development pipeline

Germany (confirmed, as of April/May 2026):

• Hamburg Bergedorf: 100 MW / 400 MWh (internally developed, ready-to-build, target op. late 2028)
• Saxony-Anhalt Döllnitz: 63 MW / 257 MWh (acquired)
• Saarland Gersheim: 10 MW / 20 MWh (internally developed, ready-to-build, target op. 2027)
• Total Germany confirmed: 173 MW / 677 MWh

Also developing in Netherlands, France, and Belgium — described as “multi-GWh development pipeline.”
