Industry Pain Points
The Challenges Your Clients Face Every Day
Before you can offer solutions, you need a partner who truly understands the real-world problems your customers are trying to solve.
Challenge 01
Soaring Electricity Costs & Demand Charges
Commercial and industrial operators face escalating peak demand tariffs that significantly inflate their energy bills, squeezing margins across industries.
Peak demand charges can represent 30–50% of commercial electricity bills
Challenge 02
Grid Instability & Power Outages
Frequent blackouts and unstable grid conditions across Africa, Southeast Asia, and Latin America cause operational disruptions and significant revenue losses for businesses.
Unplanned downtime costs businesses an average of $5,000–$8,000 per hour
Challenge 03
Renewable Energy Intermittency
Solar generation only works when the sun shines. Without intelligent storage, up to 30% of renewable energy is wasted due to grid curtailment or timing mismatches.
Up to 30% of solar energy wasted without paired storage
Challenge 04
Home Energy Dependence & Load Shedding
Residential customers in markets like South Africa, Nigeria, and parts of Europe are demanding energy independence solutions to escape grid vulnerability and rising tariffs.
Residential storage market growing 28% CAGR through 2030
Challenge 05
EV Charging Infrastructure Gaps
Accelerating EV adoption globally is outpacing charging infrastructure deployment, creating major business opportunities for distributors and EPC contractors.
EV charging market to exceed $140B globally by 2030
