Every day, transmission system operators (TSOs) face the challenges of ensuring the safe and reliable operation of the transmission network - in compliance with the regulatory regime under which they operate - and in the context of an increasingly complex resource mix as renewable and demand side programs increase their market share. Operators must also ensure their networks are protected from cyber threats.
Transmission operators require systems that support operational and regulatory requirements as they exist today, and can also evolve to meet the needs of the future system operator. For more than 30 years our energy management system (EMS), using our advanced network applications, has assisted in the safe and reliable operation of power systems throughout the world. Our EMS has been independently tested against cyber security threats and we are at the forefront in the modeling of renewable resources and their impact on the transmission system.
