NEI is responsible for producing the complete electrical engineering design documents for the interconnection of the plant to the building. Also, NEI provided the design for the protective relaying required by the utility for additional safety. NEI performed short circuit and coordination studies and provided relay settings. NEI also specified all equipment and procured the major equipement and worked with the contractor during construction. NEI commissioned electrical system before startup.

The complete design consisted of the interconnection through the building electrical system to Public Service of Colorado's service feeding the building. In addition the turbine was connected such that in the event of a failure of the utility the microturbine would supply standby power to the building. Turbine operation is completely automatic.

NEI coordinated the design with the utility and with the Denver Building Department to comply with all regulations and requirements of the National Electrical Code and all local building codes.

NEI provided the following services:

• Conceptual and detailed design
• Relay panel design and wiring diagrams
• Procurement of major equipment
• Relay settings
• Coordination with local building authorities
• Project engineering support
• Coordination with utility
• Aid during construction
• Help during startup and commissioning
