Battery Energy Storage
Commercial Battery Energy Storage in South Africa — Independent BESS Advisory
BESS is no longer just a backup power solution. For South African businesses, it's now a financial tool — reducing peak demand charges, maximising solar self-consumption and providing operational resilience.
Why invest
Why South African businesses are investing in BESS
Between rising Eskom tariffs, demand charge structures and an increasingly unreliable grid, BESS delivers measurable returns well beyond load shedding protection.
Peak Demand Reduction
Demand charges can represent up to 40% of a commercial electricity bill. BESS discharges during peak windows, flattening your load profile and reducing the tariff component most businesses overlook.
Solar Self-Consumption
Without storage, excess solar generation is fed back to the grid at a low rate or wasted. BESS stores that energy and deploys it when your panels aren't producing — significantly improving your solar ROI.
Energy Resilience
A correctly sized BESS provides seamless backup during load shedding or grid outages — keeping critical operations running without the running costs and emissions of a diesel generator.
Independent process
SOLINK's independent BESS advisory process
SOLINK does not sell or install battery systems. Our recommendations are based entirely on what is right for your energy profile — not on what a supplier wants to move.
-
STEP 01
Energy & Demand Profile Analysis
We analyse your half-hourly consumption data and demand profile to determine exactly how BESS can deliver the greatest financial benefit for your specific site — before any system is specified.
-
STEP 02
System Sizing & Technology Selection
We size your BESS correctly and select the most appropriate battery technology — LFP, NMC, or alternatives — based on your application, cycle requirements and budget.
-
STEP 03
Procurement & Contractor Management
We develop a detailed RFP and run a competitive procurement process across pre-qualified BESS installers — ensuring you receive the most cost-effective, technically sound proposal.
Standalone or integrated
Standalone BESS or Solar + Storage integration
SOLINK advises on both standalone battery storage systems and fully integrated solar PV + BESS solutions. Whether you already have a solar installation or are planning a combined system from scratch, we ensure the two technologies are optimised to work together — not just bolted on.
