The estimated performance period is one year, and the primary NAICS code is 335311 with an 800-employee size standard. Interested firms must submit a maximum 8-page response demonstrating experience with similar multi-megawatt HVPS projects using 24-pulse SCR technology and copper-wound transformers.
