The PVS is to be designed, engineered and constructed in accordance with Milford Haven Port Authority’s requirements as defined in this RFP and the EPC agreement. The PV system shall be connected to a 33KV metering circuit breaker installed by the local distributed network operator (Western Power Distribution) connected to a tee in the overhead cable line between the Steynton and Milford Haven 33KV/11KV substation that runs through the site at Liddeston Ridge (as described in the connection agreement, see Appendix A). The primary role of the contractor is to execute a Design-Build Agreement, provide turnkey planning, design, engineering, labour, materials, delivery, installation, and commissioning of a cost-effective and energy efficient solar PV system together with associated infrastructure, to maximise the use of the solar resource at Liddeston Ridge. The targeted size of the solar installation is 5.0MWp however consideration will be given for proposals that maximise the return on investment of the solar resource at the site. The project is to be completed within 3-months from the issuance of the Notice to Proceed (NTP) instruction. The successful EPC shall provide qualified personnel for services, including—but not limited to the following tasks: 1. Turnkey planning, design, engineering, labour, materials, delivery, installation, monitoring and commissioning of a cost-effective and energy efficient solar PV system. 2. Warranties & Guarantees. 3. Provision of Bank Guarantees and Insurances. 4. O & M support for the site. 5. A full & comprehensive insurance wrapper for the complete EPC Contract. 4 Milford Haven Port Authority has engaged Pure Wafer International (PWI) in a consultancy capacity to manage the EPC procurement process on their behalf. MHPA have also obtained the necessary planning approval for the PVS from Pembrokeshire County Council and also have a connection agreement with Western Power Distribution for connection to the 33KV line at the site.
