The complete design consisted of the interconnection and auxiliary power design for a 50 MW gas turbine.  The generator transformer was a 36/50/67 MVA 13.8 to 69 kV transformer delivering power to the 69 kV sub-transmission system and the auxiliary plant loads.

NEI was responsible for producing the complete electrical engineering design documents for the interconnection of the plant to the utility.  Also, NEI provided the design for connection of all electrical plant loads and all protective relaying.  NEI performed short circuit and coordination studies and provided relay settings.

NEI also aided the local utility during construction and startup and commissioning.  NEI programmed and tested the relays and coordinated all design problems with the local utility.

NEI provided the following services:

• Conceptual and detailed design
• Relay panel design and wiring diagrams
• Submittal evaluation for major equipment
• Relay settings
• Equipment testing specifications
• Project engineering support
• Coordination with utility
• Aid during construction
• Help during startup and commissioning
