Power rental market remains fragmented as Aggreko leads 2024 sales

The Business Research Company says the global power rental market is still split across many competitors, with Aggreko plc holding the top spot in 2024 sales at 3%. The report points to rising demand for temporary, reliable and fuel-efficient power as data centers, infrastructure projects and emergency users lean on rental fleets.

Why it matters: - The power rental market is becoming more important as industries seek temporary power that can be deployed fast, scaled up or down, and kept reliable. - Competition is being shaped by capital intensity, emissions rules, complex logistics and the need for smarter fleet management. - The report says fleet refurbishment, hybrid systems and digital monitoring are becoming key ways rental providers protect margins and improve uptime.

What happened: - The Business Research Company released a 2026 power rental market report covering market size, trends and a 2026-2035 forecast. - Aggreko plc led global power rental sales in 2024 with a 3% market share. - United Rentals Inc., Caterpillar Inc. and Cummins Inc. each held 3% shares, while Ashtead Group plc, Atlas Copco AB, Herc Rentals Inc. and APR Energy Ltd. each held 2%. - Generac Power Systems Inc. and Wärtsilä Oyj each held 0.1%. - The market is fairly fragmented, with the top 10 players accounting for 20% of total revenue in 2024.

Between the lines: - The concentration data suggests no company has overwhelming control, so share gains may depend more on execution than scale alone. - The mix of equipment makers, rental specialists and industrial service firms shows the market is tied to both asset ownership and service delivery. - Demand from hyperscale cloud providers, utilities and large contractors points to a market that is increasingly linked to data infrastructure, grid resilience and project-based energy needs. - In April 2026, Finning Power Rental launched a rebuild program refurbishing a 1000kVA Cat XQ1000 generator powered by a C32 engine. - The program includes engine overhauls, component replacement, alternator rewinding and testing, and is designed to extend equipment life by up to 12 to 14 years.

What's next: - The report expects strategic collaborations, fleet expansion and continued innovation to strengthen leading companies' positions. - More rental providers are likely to invest in hybrid power systems, predictive maintenance and faster deployment models as customers demand lower downtime and better fuel efficiency. - The Business Research Company also highlighted updated 2026 report features, including TAM analysis, company scoring matrices, forecasting dashboards, market hotspot infographics and technology trend analysis.

The bottom line: - Power rental remains a fragmented market, but the companies that combine fleet depth, digital tools and rapid deployment appear best positioned to win new work.
