What emost does

emost AG is a privately held Swiss company, founded in 2022 and headquartered in Dietikon, that designs, sells, and rents mobile battery storage systems intended to displace diesel generators on construction sites, events, and industrial projects. Its core product line is the Butler series — the compact Butler S (50 kVA / 25 kWh) for smaller sites and events, and the high-capacity Butler M (150 kVA / 150 kWh) for large construction, major events, and critical backup applications — complemented by the LinkDuo CEE125 power-distribution accessory and the Smart IoT Platform that provides remote monitoring, situation-based alerts, and remote intervention across the deployed fleet. Trailer-mounted mobility and Swiss-engineering positioning underpin the value proposition, with the company claiming up to 60% lower lifetime operating cost versus diesel and 18 tonnes of CO2 saved per unit per year. The commercial model combines direct hardware sales and rental solutions sold exclusively within Switzerland through a website-driven, sales-led motion: prospects request a free trial or a quote (typically returned within 24 hours), with a 48-hour typical setup, and ongoing Swiss-based service and maintenance support. The named customer base spans more than 25 Swiss enterprises across construction (Implenia, KIBAG, Robert Aebi, Ammann), energy (AXPO, Nexans), rail and transport (SBB CFF FFS, DB), events (Red Bull Erzbergrodeo), agriculture, and electrical services, with the company serving eight marketed use-case segments from construction and infrastructure through emergency backup and film production.

Broad incumbents

• Caterpillar: Global heavy equipment leader whose Cat Rental network supplies mobile power generation including diesel gensets and emerging battery storage solutions. Larger incumbent offering emost's category as part of a broad construction equipment and power generation portfolio.
• Volvo Construction Equipment: Global construction equipment OEM with a stated roadmap to electrify compact machines and supporting site power. Broad incumbent entering battery-electric construction equipment that overlaps with emost's construction site power focus.
• Generac: US-based incumbent in residential, commercial, and industrial power generation with a rapidly expanding battery energy storage systems portfolio. Broad incumbent incumbent in the genset/emission-free power space that emost serves at smaller scale.
• Hilti: Liechtenstein-based construction tools and services company operating its own battery platform (Nuron) and equipment fleet management for jobsites. Premium industrial brand comparable to emost's positioning, with a broader tools/services portfolio.
• Honda Power Equipment: Honda's generator and portable power division, a long-standing mobile generator incumbent that is extending into battery-based portable power products. Broad incumbent whose traditional generator business emost is directly displacing at the small-to-mid scale.

Direct peers

• Aggreko: UK-headquartered global leader in mobile temporary power and temperature control rentals, including a growing fleet of battery energy storage units. Directly comparable in target market (mobile power rental for construction and events), revenue model (rental-led), and product category (battery storage replacing diesel gensets).
• Wacker Neuson: German construction and compact equipment manufacturer with an industry-leading line of battery-electric excavators, wheel loaders, and dumpers, plus battery-based site power. Direct competitor in electrified construction site equipment and temporary construction power.
• EcoFlow: Portable power station specialist rapidly scaling into higher-capacity mobile battery products targeting construction and outdoor professional use. Closely comparable product category (portable/mobile lithium battery power) though primarily consumer-led with prosumer expansion.
• BLUETTI: Leading portable power station brand expanding from consumer into professional and semi-industrial mobile power use cases. Direct product-comparable in mobile battery-based silent/clean power generation, though serving different end-customer scales.
• Atlas Copco Power & Flow: Swedish industrial group with a dedicated Power & Flow division offering mobile generators, light towers, and increasingly battery-driven energy storage solutions for construction. Direct competitor in mobile temporary power with comparable product roadmap toward electrified construction site power.
