Generating utility-scale solar
energy from ground-mounted arrays

A utility-scale solar farm generates large amounts of solar energy equivalent to a full-scale power utility. The solar energy generated is supplied to the local electricity grid operator and an offtaker can enjoy a steady source of renewable energy through a long term Power Purchase Agreement (PPA).

How off-site PPA works:

An off-site PPA is a contract associated with the virtual supply of renewable energy generated from a utility-scale solar project, which is connected to the transmission network of Singapore’s electricity system.

With solar energy harnessed from Sembcorp’s utility-scale solar project, an off-site PPA arrangement is suitable for businesses with massive green energy requirements.

Case Study

Sembcorp’s solar farm in Tuas

Following the successful roll out of the first two phases at Jurong Island and Changi Business Park, JTC issued a tender for the third phase of its SolarLand programme in February 2020. SolarLand Phase 3 maximises the use of over 56 hectares of temporary vacant land all across Singapore. Its system is made modular and flexible by using mobile PV panels and hybrid SPPG substations which can be redeployed when the land is needed for other uses.

The SolarLand program aims to overcome space constraints and high capital costs while at the same time, reduce the carbon footprint and optimise the use of industrial land to contribute clean energy to Singapore.

Sembcorp’s solar farm in Tuas is one of the sites under JTC SolarLand Phase 3. It has a combined solar capacity of 17.6MWp and is built across two sites. Estimated to be sitting on close to 10 hectares of temporary vacant land, it is also Singapore’s first solar farm with an integrated rainwater harvesting system.

Rainwater is collected via a drainage network built between the solar panel arrays and connected to an underground water storage tank that has been constructed using a geocellular system. The treated rainwater, which has been neutralised and free of contaminants and odour, will primarily be for non-potable use to further clean the solar panels onsite, as well as for solar panel cooling purposes.

The Solar PV system of 17.62MWp will help avoid approximately 9,000 tonnes of carbon dioxide and treats up to 170,000m3 of rainwater annually , which equates to:

Powering approximately
4,700 4-room
HDB Flats per year

Planting almost 150,000
trees annually

Reclaiming an equivalent of 68
Olympic-sized swimming pools annually
