• Uses industry standard programming languages
• Microprocessor-based controller
• Fast load-shedding timing coordinates with backup frequency load shedding
• Installations in the United States
• Local customer support for current and future OCSD projects
Also, reduced staff training and less spare parts
Recommendations - Item 11
• Authorize staff to specify Schweitzer Engineering Laboratories as
the sole source provider for current and future projects
equipment, materials, and services for electrical power system
protective relays and load-shedding systems at Plant Nos. 1 and 2;
and
• Authorize staff to negotiate service agreements for services
related to protective relays and load-shedding systems for current
and future projects, and for on-going operations and maintenance
at Plant Nos. 1 and 2; and
• Ratify the addition of Schweitzer Engineering Laboratories
to the list of pre-approved Original Equipment
Manufacturers for procurements under $100,000 for
equipment, materials, and services for electrical power
system protective relays and load-shedding systems.
