What Green Voltage does
Green Voltage Limited is a UK-based specialist in silent, zero-emission battery power systems for film, television, and event production environments. Founded in October 2018 by industry professionals David Sinfield and Adam Baker — whose combined 90+ credits span major franchises including Bond, Star Wars, Indiana Jones, La La Land, Marvel, DC, and Disney — the company was established to displace diesel generators in production settings where noise, fumes, and fuel handling create operational and environmental friction.
The company's product platform centers on the proprietary GV Kube 10k, a British-engineered and assembled LiFePO4 battery unit delivering 6 kVA continuous output, 10.2 kWh usable capacity, integrated 4G LTE telemetry with GPS, parallel-link scaling to 50+ kWh, dual MPPT solar input, and an IP54-rated aluminum enclosure operating from -20°C to +50°C. The platform is supported by a VRM cloud portal for remote monitoring, runtime tracking, asset geofencing, and carbon-savings reporting. A larger GV Kube 150k unit is in development to extend the proprietary line. Beyond the Kube, the company operates a hire fleet spanning third-party units from Instagrid (One Max), VOLTstack (5k), and Wattman (10k), through to trailer-mounted EGEN systems (20K, 30K, 45/100, 50K) that collectively cover 2 kWh to 120 kWh capacity ranges.
Commercially, Green Voltage operates a sales-led, direct-engagement model with two revenue streams: (1) rental of silent battery power systems to productions and events on a project basis with on-site support, and (2) outright sales of the GV Kube 10k to fleet operators, production companies, and trade buyers. Pricing is quote-based with no public list. The customer base is concentrated in UK film and television, with logos including Warner Bros.'s Wonka, Sony Pictures's Venom 3, Eon Productions's No Time To Die, and BBC/Netflix's Peaky Blinders – The Immortal Man. Operations are headquartered in Staines, United Kingdom, with a team of 1–10 employees. No external funding rounds have been disclosed.

Green Voltage competitors and assessment
Company assessmentEmerging players
- Jackery: Consumer-leaning portable power station brand scaling up capacity tiers. Adjacent competitor at the lower-capacity, prosumer end of silent battery power where GV also competes via the Instagrid One Max in its hire fleet.
- EcoFlow: Fast-growing portable power station maker expanding from consumer/prosumer into professional and light-commercial use cases. Partial overlap with GV at the lower-kWh end of the market.
Direct peers
- Instagrid: German portable-battery specialist whose Instagrid One Max (2 kWh) is itself in Green Voltage's hire fleet. Direct head-to-head competitor in silent, lightweight battery power for film, events and trade.
- Prolectric: UK-based specialist in solar-hybrid and battery temporary power for construction sites, events and film productions. Closely comparable in geography, customer verticals and zero-emission positioning.
- Portable Electric (VOLTstack): Canadian maker of VOLTstack mobile battery power stations (VOLTstack 5k is in GV's hire fleet). Closely comparable in offering mobile Li-ion/LiFePO4 power to film, events and construction customers.
Broad incumbents
- Aggreko: Global temporary-power incumbent (diesel/gas generators) now expanding into battery and hybrid solutions. Competes with GV for large-scale film, event and industrial temporary power contracts, with far greater capital and geographic reach.
- Caterpillar Energy & Transportation: Global diesel-generator and power-systems incumbent progressively adding battery-energy-storage product lines. Relevant as a broad incumbent entering mobile battery power for the same end customers.
- Atlas Copco Power Technique: Global industrial equipment major with a mobile power division covering generators, energy storage and hybrid solutions. Overlaps with GV on temporary silent power for events, construction and film.
Regional players
- Power Electrics: UK generator hire specialist with a national depot network serving events, film and construction. Comparable in UK event/film temporary-power customer base, currently more diesel-led and now adding low-emission options.
- Shenton Group: UK provider of generators, UPS and emerging battery power solutions for events, construction and industrial sites. Comparable in geography and customer base but broader/less specialised in film-grade silent power.
