Ferroamp Varberg Energi Volvo Penta Electric Boat V2G Pilot (2026)

Ferroamp press release (26 August 2026): “Electric boat batteries — an untapped resource for the electricity grid.” An extension of the existing Ferroamp/Varberg Energi V2G collaboration (documented at Ferroamp from its May 2025 villa/EV demonstration) into a new asset class — electric boats — with Volvo Penta as the boat-technology partner.

Partners: Ferroamp, Varberg Energi (aggregator role), Volvo Penta (boat technology) Funding: Västra Götaland Region

Key findings

• Two electric boats (with Volvo Penta technology) connected to the grid via Ferroamp V2G chargers and inverters; Varberg Energi acted as aggregator, signalling when to charge or discharge
• Rationale: many recreational boats sit idle on land through the Swedish winter — their batteries can instead support the grid (ancillary services, peak cutting, price-fluctuation management) during the winter, and availability known in advance is what ancillary-service markets require
• Ancillary-service qualification: the release states the system “meets the requirements of the fastest ancillary services” — it does not name the product; reaction time to a grid signal was the focus of the project’s testing
• Scale argument: boat batteries are framed as often offering around ten times the capacity of residential batteries — a distinct DER category from residential V2G/V2H that the wiki has not previously covered

Relevance to existing wiki topics

• Ferroamp — a direct extension of the existing Varberg Energi collaboration beyond the May 2025 villa/EV demonstration into a new asset class (boats), answering the page’s own data gap about what came after that first demonstration
• Vehicle-to-Grid — a genuinely new V2X asset category (recreational marine batteries) not previously represented in the wiki’s pilot table
• Balancing Markets — plausible FCR-D application, though not explicitly confirmed in this release
