History of innovation

Since our beginning in 1975 as a manufacturer of state-of-the-art remote terminal units, to our present position as a major supplier of utility automation systems throughout the world, we\'ve created a record of industry firsts that parallels, and has often led, the evolution of energy distribution and management.

We have provided supervisory control and data acquisition (SCADA) systems, energy management systems, distribution management systems, and system components for electric, gas and water utilities since 1975.

We manufacture and deliver products and systems necessary to effectively control the generation, transmission and distribution of power.

In 1977, we introduced a small microprocessor to meet the distinctive needs of rural electric authorities and municipalities. In 1983, a SCADA master computer that could accommodate bigger distribution management systems was showcased. We delivered the world\'s first UNIX-based SCADA system in 1991, and the first energy management system employing fully-integrated power applications on an open system UNIX platform in 1995.

Our most recent achievements include the world’s first fully integrated DA/DSM system, the industry’s first integrated real-time outage management system and the newest fault detector module, jointly developed with the Portuguese Automation unit. 

We offer the broadest range of high performance, scalable “intelligent grid” solutions for SCADA, distribution management, distribution automation, substation automation and energy management available today - all on a common platform
