GEMS Site Controller enables participating generation owners to meet secure operational data telemetry requirements.
Greensmith Energy, a Wärtsilä Company, today announced that the California Independent System Operator (CAISO) has certified the Greensmith GEMS Site Controller as a Remote Intelligent Gateway (RIG) for direct telemetry of participating generators and loads within the CAISO balancing authority area.
Metering and telemetry are mandatory tools used to ensure operational visibility and accurate revenue accounting for the ISO grid. The RIG allows CAISO to access generator information and/or controls from the ISO’s Energy Management System (EMS) in order to provide ancillary services and supplemental energy. Generation facilities that want to interconnect at the transmission level must install a field RIG unit or an acceptable equivalent that can interface with the EMS.
For RIG qualification, devices must undergo rigorous testing and verification for data accuracy, integrity, security, and communications. The Greensmith GEMS Site Controller exceeded all certification requirements, including secure communications via Transport Layer Security (TLS); X.509 certificate generation with the option of 1024- and 2048-bit RSA key sizes; the ability to store CA certificates issued by CAISO; a data integrity check on all values by reporting information on quality; configurable scaling of analog inputs; and a point-to-point check validating the correct scaling of signals.
GEMS Site Controller is a highly scalable power plant controller that embodies intelligent applications that focus on monitoring and operating energy storage power plants and hybrid power plants formed by energy storage, thermal generator, wind and solar combined. Greensmith Energy is fully qualified to provide the design, integration and commissioning services required to bring its RIG online and comply with CAISO requirements.
Wärtsilä closed the acquisition of Greensmith Energy Management Systems Inc in July 2017. Greensmith is a leading energy storage integrator with over 150MW deployed in North America. Greensmith provides a full range of solutions including the turnkey delivery of storage systems complete with software controls to maximize returns for system owners/operators.
