Octave.energy’s €10M Series A: Profitable Batteries Meet Grid Congestion
SPDG Growth led Octave.energy’s €10M Series A (equity + flexible debt) after €16M 2025 revenue and three profitable years — Belgian BESS+EMS expansion into NL, France, and Germany.
Editorial team
SPDG Growth led a €10 million Series A for Mechelen’s Octave.energy in early September 2026, structured as equity plus flexible debt, with imec.istart, BNP Paribas Fortis, and KBC participating (Made in, n24).
Spine: this is expansion capital for a profitable installer-led BESS+EMS business, not a pre-revenue climate science bet — grid congestion is the demand driver.

Who uses the product — and for what job
Users: industrial sites, SMEs, and agricultural enterprises fighting grid congestion, peak prices, and electrification constraints.
Job: pair first-life LFP batteries with Octave’s EMS so sites can store power, cut peaks, coordinate EV charging, and monetize flexibility — with the customer free to choose their market optimizer (company).
CEO Maxime Snick’s framing (Made in): electrification of heat, industry, and transport is colliding with net congestion as the bottleneck.
Why now
- Western European summers and industrial electrification made capacity constraints operational, not theoretical.
- Banks in the syndicate (BNP Paribas Fortis, KBC) fit asset-backed clean-infra stories better than pure software VCs.
- Proceeds: NL / France / Germany sales-service hubs via installation partners; EMS/asset-management platform depth.
Why SPDG — portfolio fit
SPDG already backed the seed and is doubling down on a cash-flowing hardware+software operator. Bank participation signals underwriting comfort with receivables and project economics.
Likely founder rationale: raise patient expansion capital from an existing family-office lead that understands Belgian industrial GTM, plus banks that can support working capital as deployments scale.
SPDG Growth, imec.istart, BNP Paribas Fortis, and KBC are not in our fund directory — editorial only.
Competitive map
| Approach | Tradeoff |
|---|---|
| Utility-scale storage only | Large projects; misses behind-the-meter SME pain |
| Pure EMS software | Asset-light; depends on third-party battery quality |
| Commodity battery installers | Price competition; weak software moat |
| Octave BESS+EMS integration | Higher attach; execution-heavy multi-country rollout |
What is not proven
- Exact equity vs debt split inside the €10M not disclosed.
- Valuation not disclosed.
- Gross margin on hardware vs software mix not disclosed.
Practical takeaway
- Founders (climate): Profitability plus named logos changes Series A conversations in Europe’s selective climate market.
- Investors: Diligence partner-installer quality and service uptime — the moat is ops, not slides.
- Operators: Relevant if grid connection delays or peak tariffs already block electrification plans.
