The total value of this project will be determined by the PPA price as per the agreed bid sheet, over the term of the agreement. The scope of work is summarised in the non-exhaustive list below: full design and engineering, procurement, full MEICA installation, commissioning (including commissioning activities at point of connection), Distribution Network Operator (DNO) witnessing, testing and approval to satisfy the terms of the connection agreement or offer, supporting OFGEM accreditation for REGOs, operation and maintenance, monthly and annual reporting, training of emergency procedures, training of essential operational activities, documentation, demarcation fencing and signage, biodiversity net gain requirements and any visual impact requirements. The PV installation will be floating with a maximum capacity of 4MW. The Supplier shall design and optimise the size of the PV plant for behind-the-meter use and achieve an attractive payback period and NPV. The PV plant shall require inhibiting when the board is being fed from the generator or in an island situation. The PV plant shall utilise the most efficient and appropriate components to ensure an efficient and low-maintenance system. The scope will be awarded via PPA model, with a subsequent Lease Agreement, with only one supplier to be awarded.",
