INTRODUCTION: This is the initial step in the planning process for the procurement of a power controller/regulator to control the input power to a 9 MW doubly fed wound rotor induction motor which drives a 95 MVA salient pole Generator. This controller/regulator will drive current in the induction motor rotor windings. This Motor Generator Set will be used at the Alternating Gradient Synchrotron (AGS) at Brookhaven National Laboratory (BNL) managed by Brookhaven Science Associates (BSA), as defined in the Statement of Work (SOW), attached. BSA anticipates conducting a competitive acquisition for this effort. The North American Industry Classification System (NAICS) code is anticipated to be 335999 – All Other Miscellaneous Electrical Equipment and Component Manufacturing. The size standard for NAICS code 335999 is 600 employees. INSTRUCTIONS: All interested respondents capable of providing services for the requirements outlined in the attached Statement of Work (SOW) are invited to respond electronically with a Statement of Capabilities (SOC) demonstrating the ability to meet the requirements.

Description of capability to meet the requirements identified in the SOW. 2. Overview of company’s experience in power controller/regulators and motorgenerators. Including a list of three similar power regulators successfully designed,manufactured, and installed. 3. Familiarity with motor-generator applications in high-energy physics and/or otherscientific/industrial environments. 4. The Government is also assessing the availability of domestic end products, asdefined under applicable statutes and regulations. The Offeror is requested toconfirm if the proposed system is considered a domestic end product as defined atFAR 25.101(a). If not, what is the country of origin of the product? 5. Respondents are requested to provide if the proposed system is a “commercialproduct” as defined at FAR 2.101. Please provide supporting documentation or justification for the commerciality determination in your response.
