        "description": "UKIFS (now UKFE) has conducted this Procurement for a Construction Partner, who, together with a Fusion Partner (determined to be United Kingdom Atomic Energy Authority (UKAEA)), will bring together and develop extensive industrial capabilities to design and build a UK prototype fusion energy plant capable of delivering net-energy to the grid, and build a world-leading fusion delivery industry. The Procurement was originally divided into two lots: * Lot 1: Engineering Partner (EP) * Lot 2: Construction Partner (CP) However, Lot 1 - EP has since been cancelled. Lot 2 - CP is now the only Lot included in this Procurement exercise. The contract term for Lot 2 will expire 31 March 2029, followed by three (3) optional extension periods of four (4), six (6) and seven (7) years. UKFE will have the right to exercise an extension option at six (6) months' notice. The maximum contract duration will be twenty (20) years with an estimated value of PS10,000,000,000 across this period.",
