Llancayo Solar Farm of 5MW
Our client had an urgent requirement to deliver a large-scale project (5MW in total) in a very short space of time. The UK Government had given notice of a reduction of the FiT tariff for PV systems above 50KW during the Fast Track Review. The client had an issue sourcing an experienced EPC contractor that would commit to finishing the project before August 1st 2011.
SES were sought to provide EPC (Engineering, Procurement and Construction)for the project. An initial site visit ensued, and consequently followed with employing SES fast track project evaluation and reporting techniques. This enabled the client to not only feel comfortable the project would be delivered, but that it would be constructed in such a way that would maximise output, re-use materials where possible and be sympathetic to surroundings and local heritage.
After delays out of the control of SES, the contract was finally signed on 15th July and the project commenced with the initial delivery of materials on the 18th. SES sourced labour and materials locally where possible, assisting the local economy.
Over 100 people were employed during an operation that initially lasted two weeks, working around the clock.
One constraint on the project was that a suspected Roman Temple was buried under a large portion of the project site, this was later confirmed during the build. Liaising with the local archaeologists of Monmouth Council, SES ensured that the Temple remained preserved and the location recorded before being re-covered.
Phase 1 commissioning and G59 testing at 11kV was carried out by Western Power Distribution (the District Network Operator) which passed first time on July 29th 2011. Phase 1 consisted of 16,997 modules (3,900KW) and 3,000KW of inverters.
Phase 2 took the project up to 5MW with an additional 1.1MW being installed under the extension allowance, making a total of 21,735 modules.
The projects performance is constantly being monitored and has shown to be approximately 8.5% higher than originally anticipated, this is down to two key factors:
1. Proven SES system design, minimising loss.
2. High quality materials (Solar Max inverters and Risen Modules)
Furthermore, the project comes with an insurance policy that covers the client for any eventuality including loss of production (even loss of solar irradiance against predictions) and covers the inverters and modules for a period of 25 years. This makes it very attractive to investors looking for a long-term guaranteed return, because no matter what the eventuality, the insurance cover ensures that payments will be made.
A long-term service contract covers the project for general operations and maintenance and includes system monitoring whereby performance can be measured by the hour, minute, day, or chosen time period. The web-based system ensures that clients can monitor the performance of the system at any time.
