Producer
Perkins Engines
Perkins Engines Company Ltd. (Peterborough, UK; wholly owned subsidiary of Caterpillar Inc. since 1997; ~£1B+ revenue) is the dominant manufacturer of diesel engines for smaller standby gensets in the 5kW to 500kW range — the segment serving telecom towers, small hospitals, commercial buildings, and light infrastructure. Perkins is the engine of choice for most portable and standby telecom tower generators globally. Primary manufacturing at Peterborough, UK (world's largest single-site diesel engine plant, ~3,000 employees; opened 1932); secondary manufacturing in Chennai, India (Perkins India, serving Asia-Pacific). Perkins engines power an estimated 1 in every 5 gensets globally by unit count. The Perkins 1100 and 1500 series (diesel) are found in telecom backup across Africa, Asia, and Latin America. The global telecom tower genset market — estimated 4-6 million engines in service — is heavily dependent on Perkins supply.

Chokepoint2023
Perkins Engines (Peterborough, UK; Caterpillar subsidiary) manufactures the diesel engines powering an estimated 1 in 5 standby gensets globally by unit count, with dominant concentration in the global telecom tower segment (estimated 4-6 million towers each with 1-3 backup genset engines). In Sub-Saharan Africa and South Asia, where grid reliability is lowest and diesel gensets are the primary power source for telecom infrastructure, Perkins has an estimated 60-70% market share. The Peterborough plant (opened 1932) is the sole high-volume production site for Perkins' telecom tower engine range. A disruption to Peterborough would directly threaten mobile connectivity infrastructure across Africa, South Asia, and Latin America — the regions most dependent on diesel backup for telecom operations. Perkins' strategic role in telecom tower backup is almost entirely absent from Western critical infrastructure analyses because it is a consumer goods-adjacent 'engine subsidiary' rather than a named critical facility.
Perkins Engines Company Ltd. ↗Did you know2024
Perkins Engines dominates the 5-500kW diesel engine range that powers: (1) telecom tower backup generators globally — when the power grid fails, Perkins engines keep 4G and 5G base stations running for emergency communications; (2) agricultural tractors across Africa, South Asia, and Latin America; and (3) construction equipment (skid steers, telehandlers, smaller excavators) that builds infrastructure. The 5G/cellular emergency communications supply chain, the food production/agricultural supply chain, and the construction supply chain all share Perkins's Peterborough engine manufacturing base and global distribution network. A Perkins production disruption would simultaneously affect mobile network resilience in a hurricane, tractor availability for food production in India, and backhoe availability for infrastructure construction.
Perkins Engines ↗Origin2023
Perkins Engines was founded in 1932 in Peterborough, Cambridgeshire by Frank Perkins, who left the Lawrence Engineering Service to establish his own diesel engine company during the Great Depression. Perkins succeeded by making smaller, lighter diesel engines practical for agricultural and commercial applications that previously used petrol engines — contributing to UK agricultural mechanization post-WWII. The company grew significantly as British agriculture, construction, and industrial equipment manufacturers adopted Perkins diesel. Caterpillar acquired Perkins in 1997 for £1.13 billion, adding the UK engine maker's global agricultural and small genset distribution network to Caterpillar's industrial engine portfolio.
