Commercial energy storage case in Southeast Asia

Project Background

Overview of the mall:

Scale:4-story commercial complex (35,000㎡), annual electricity consumption 4.2GWh

Pain points:

Electricity costs account for 28% of operating costs (electricity prices fluctuate between $0.18-0.32/kWh)

High backup costs for diesel generators (US$60,000/year)

Idle roof space (8,000㎡ available)

Comparison of operational results (18 months after implementation)

Annual electricity bill was 1.02M USD before transformation and 0.61M USD after transformation, a 40% reduction

Diesel consumption was 85,000L/year before transformation and 9,000L/year after transformation, a 89% reduction

PV penetration increased from 0% to 34%

Power outage losses increased from 230,000 USD/year to 0 losses, achieving 100% power outage operation guarantee

Typical scenarios:

Electricity price arbitrage: Discharge during the peak electricity price period from 2 to 5 p.m., saving up to $1,850 per day

Emergency response: When the power grid fails in April 2024, the energy storage system automatically switches to ensure constant temperature and humidity in the jewelry store

Carbon trading income: Obtain Malaysian carbon credits (VCUs), with an annual increase of $42,000
