What is Battery Energy Storage?

Battery Energy Storage Systems (BESS) are fundamentally changing the energy landscape, playing a pivotal role in accelerating the global shift from fossil fuels to renewable sources.

For businesses in Malaysia, BESS is the key to energy resilience. It optimizes renewable integration, minimizes energy waste, and acts as a dispatchable power source to manage fluctuations from intermittent sources like solar and wind.

BESS Application Across Segments

Utility Scale

Provides essential grid services like frequency and voltage regulation which are vital for stability. It acts as a dispatchable power source to manage fluctuations from intermittent renewables like solar and wind.

Strategic asset for cost and operational optimization. Its primary function is to reduce electricity costs through peak shaving and load shifting. BESS also ensures power reliability and backup, crucial for preventing costly downtime in facilities like data centers.

For homeowners with solar PV systems, BESS stores excess energy generated during the day for use at night, lowering bills and maximizing selfconsumption.

Manages high-power demand of fast chargers by charging slowly from the grid and discharging rapidly to the EV. This avoids the need for expensive grid upgrades and manages the Maximum Demand (MD) of the charging station.

Key Benefits of BESS

The benefits of deploying BESS are multifaceted and extend beyond simple cost reduction. They include:

Financial Savings

By strategically managing energy consumption, BESS enables peak shaving and load shifting, directly reducing high Maximum Demand (MD) charges and overall electricity bills.

Grid Stability

BESS provides crucial grid services, such as frequency regulation and power smoothing, which enhance the reliability and resilience of the electrical network.

Renewable Energy Integration

BESS addresses the intermittency of solar and wind power, allowing for a higher penetration of renewable energy into the grid. It stores surplus energy when generation is high and releases it when needed.

Operational Reliability

BESS can act as a reliable backup power source, ensuring business continuity during unexpected grid outages.

Environmental Sustainability

By facilitating the greater use of renewable energy, BESS contributes to a lower carbon footprint and helps businesses meet their sustainability goals.

Maximize Savings with Peak Shaving using our Solution

Addressing TNB's RP4 Tariff

Under TNB’s RP4 structure, Commercial & Industrial (C&I) businesses face high Maximum Demand (MD) charges. By discharging stored energy during peak hours, BESS “shaves” the top off your energy usage spikes.

Reduce Max Demand up to 65%

Our case studies show MD reduction ranging from 20% to over 65% by adopting Solarvest BESS Solution.

Potentially achieve a rapid return on investment (ROI) within 3 years, allowing you to enjoy savings faster and reinvest in other critical business areas.

Implementation Strategy

Service Provider Selection

A key first step is partnering with a clean energy expert with a proven track record. Solarvest’s deep experience in the Asia Pacific region ensures a seamless process from consultation to commissioning and beyond.

Assessment & Customization

Solarvest’s team conducts a thorough analysis of a client’s facility’s energy consumption and load profile using its advanced AIES (AI-driven Energy Simulator). This data driven approach allows for the precise sizing and design of the BESS and a customized charge/discharge strategy to maximize savings.

Real-time Monitoring & Reporting

Following installation, the EPMS (Energy Performance Monitoring System) provides continuous, real-time tracking of the system’s performance. This ensures that the BESS operates at peak efficiency and allows for proactive adjustments to be made over time, guaranteeing a consistent return on investment.
