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).
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.

Singapore's first solar farm with an integrated rainwater harvesting system
Our integrated rainwater harvesting system allows us to collect and neutralise rainwater so that the treated water can be employed for primarily non-potable uses, such as to further clean the solar panels onsite and for solar panel cooling purposes.
This system can treat up to 170,000m³ of rainwater annually, which equates to reclaiming an equivalent of 68 Olympic-sized swimming pools annually.
*Meeting the daily electricity needs of around 24,000 four-room public housing flats in a single discharge.
