BESS Peak Shaving for a Major Singapore Commercial Facility
Verified outcomes from energy saving, industrial IIoT, digital twin, and broadcast infrastructure deployments across Singapore.
Client Context
A major Singapore commercial and retail development with a peak electrical demand exceeding 1,200 kVA sought to reduce its SP Group Maximum Demand (MD) billing and prepare for BCA Green Mark recertification. The facility operates 18 hours per day, with peak demand concentrated in the 09:00–21:00 window, resulting in significant MD charge liability under Singapore's commercial electricity tariff.
Challenge
The client required a BESS solution that: (1) delivered measurable MD reduction under Singapore's electricity tariff structure; (2) met BCA Green Mark documentation requirements; (3) could be installed within the existing plant room space without structural modification; and (4) was certified to Singapore Fire Safety Act requirements for battery energy storage in commercial buildings.
