The cost of electricity is no longer only an energy issue for South African businesses. It is increasingly a question of competitiveness, investment and long-term operational resilience.

Recent figures show the pressure on large power users. Business Day reported on 7 September that South Africa's mining and industrial majors paid Eskom R115 billion for electricity in the 2025/26 financial year. According to Eskom's annual report, industrial electricity demand fell by more than 22% over the same period as high power costs weighed on energy-intensive operations.

At the same time, major businesses are moving to alternative supply. Reuters reported on 26 August that South African mining companies are accelerating investment in renewable energy to cut costs, diversify supply and meet decarbonisation targets.

For commercial and industrial energy users, the question is no longer simply how to secure power. It is how to buy it, what to invest in, and which energy strategy makes the strongest commercial sense.

Energy procurement is becoming more complex

Businesses are now weighing several procurement options at once. Should they sign a long-term PPA? Buy through an electricity trader? Wheel renewable power across the grid? Invest in behind-the-meter generation? Add battery storage? Each option carries different implications for cost, risk, contracting and long-term flexibility.

These decisions will take centre stage at the C&I Energy + Storage Summit Johannesburg, taking place on 28–29 October 2026 at The Maslow Hotel, Sandton. The programme is built around the practical challenges facing energy buyers today, with a focus on real projects, commercial models and implementation rather than technology in isolation.

A programme built around the buyer's decisions

The summit closes with the C&I Decision Clinic: Ask the Experts, a masterclass where attendees submit real project challenges in advance and receive practical, anonymised responses from experts. Questions on the table include whether to build onsite PV or sign a wheeled PPA, how much battery storage makes commercial sense, what a bankable project preparation pack should contain, and what financiers require before term sheet stage.

It follows The C&I Energy Playbook: Five decisions business leaders need to make now, a closing panel in which the moderators of key summit sessions distil the programme into the priorities C&I businesses should act on.

Other sessions address the questions buyers are asking now:

• Energy storage beyond backup power: unlocking commercial value examines peak shaving, demand charge management, energy arbitrage and hybrid PV-plus-storage business models, along with the operational realities of dispatch, degradation and warranties.
• Making public-private engagement work for you unpacks how wheeling agreements are structured in practice, where interface risks arise, and how businesses can engage utilities and municipalities early.
• Reducing energy costs without building new generation is a case-study-led workshop on energy efficiency, operational optimisation, demand response and digital energy management.
• Projects Spotlight gives energy users the floor to share the strategies they have implemented, the lessons learned and the outcomes achieved.

The programme opens with the keynote panel Threats and opportunities in South Africa's industrial future, bringing together policymakers, industrial leaders, financiers, and energy and water experts.

Bringing energy buyers into the conversation

The summit's Hosted Buyer Programme is designed for qualified end-user energy buyers across sectors including mining, manufacturing, property, agriculture and other energy-intensive industries. Hosted buyers take part in the full programme and receive curated engagement with solution providers across energy procurement, storage deployment and project development.

Four events, one venue

The summit is co-located with the EIUG Conference, Water Security Africa and the Data Centre Summit, bringing the energy, water and digital infrastructure communities together in Sandton. It is brought to you by Enlit Africa, with ESI Africa as host media, and is accredited by the SAIEE.
