What Krill Generadores does

Krill Generadores is a Spanish specialist in temporary and emergency electrical power supply, founded in 2003 and headquartered in La Nucía, Alicante. The company rents generator sets ranging from 40 KVA to 1,450 KVA per unit, with parallel synchronization capability enabling combined capacities exceeding 25 MW. Its equipment is sourced from manufacturers including Atlas Copco, Caterpillar, AEM Spain Gensets, and Volvo Penta, and is controlled via DEIF electronic systems (AGC2, AGC4, AGC150, AGC243, DVC550). The fleet is supported by a proprietary, internally developed remote telemetry platform providing real-time generator status, geolocation, maintenance management, and remote start/stop capabilities, monitored 24/7 by in-house operators and technicians.

The company generates revenue primarily through usage-based generator rentals, supplemented by technical services (installation, commissioning, maintenance), accessories and complementary equipment (distribution panels, cabling, fuel tanks), and energy consulting for complex projects. Go-to-market is direct enterprise field sales targeting electrical utilities, industrial manufacturers, construction firms, healthcare facilities, telecom operators, agricultural operations, petrochemical sites, and event organizers, alongside a 24/7/365 emergency response service accessible via a dedicated phone line. Distribution is anchored by five regional delegations across Spain (Alicante HQ, Valencia, Zaragoza, Seville, Barcelona), enabling nationwide coverage without third-party resellers.

In December 2025, Krill Generadores was acquired by Aggreko Limited, a global temporary power operator owned by TDR Capital and I Squared Capital, with DLA Piper advising Aggreko on the transaction. The company holds ISO 9001, ISO 14001, and ISO 45001 certifications, and is registered with the Spanish Ministry of Economy as an "Empresa Productora y Distribuidora de Energía Eléctrica Móvil," a regulatory designation required to operate generator rental services in Spain. Named enterprise customers include Iberdrola (designated emergency response partner), Eiffage Energía, and Correos.
