Terrenus Energy and Digo Corporation were jointly awarded a 70 megawatt-peak (MWp) solar contract by the Housing Development Board (HDB) and Singapore Economic Development Board (EDB) in March 2022.

The project, under HDB’s SolarNova programme, will see the installation of solar panels across 1,198 HDB blocks and 57 government sites. When completed, it will become Singapore’s largest collection of distributed solar systems capable of generating at least 90 gigawatt-hours (GWh) of solar energy annually. This amount of energy is capable of powering an estimated 20,000 4-room HDB flats for one year and helps to offset carbon emissions by about 38,000 tonnes per year.

As part of SolarNova Phase 6, Terrenus Energy is developing proprietary smart electrical power meters to be installed at assigned HDB blocks. The devices will gather and track energy consumption patterns and performance data of common services such as lifts. Tapping into this data, HDB and Town Councils can compare and derive actionable insights on energy supply and demand across individual blocks in an estate.

Terrenus Energy will also be deploying Building-Applied Photovoltaics (BAPV) on some of these HDB buildings in an effort to enhance sustainable infrastructure and expand green energy innovation in the country.
