NCP Chlorchem, one of South Africa’s leading producers of chlorine and essential water treatment chemicals, has partnered with Terra Firma , a top developer of commercial and industrial solar and battery-storage projects, to launch a 27 MWp multi-phase solar initiative

This programme ranks among the largest standalone behind-the-meter solar installations in the country and will power NCP’s primary manufacturing site.

The site is designated as a National Key Point due to its vital contribution to providing safe, potable water to millions across South Africa. The solar rollout will meet a considerable portion of the facility’s power needs, with several phases already operational. More capacity is expected to be added in early 2026, and the full programme is projected for completion by the end of that year.

As core industries navigate high electricity prices, grid instability and increasing demands to cut carbon emissions, onsite renewable energy is becoming an essential part of long-term operational and financial planning.

NCP’s production processes require substantial amounts of energy, making reliable long-term energy supply and emissions reduction fundamental to its sustainability agenda. The company began its solar partnership with Terra Firma in 2023 through a 1.1 MWp pilot system, installed under earlier regulatory constraints that capped project size. After the pilot proved successful, NCP progressed to a 10 MWp second phase consisting of rooftop, carport and ground-mounted systems, now nearing commissioning. Construction of an additional 17.5 MWp is underway, bringing the total solar capacity to 27 MWp.

“As a producer of essential chemicals used in water and sanitation, sustainability is central to how we operate,” said Schalk Venter, managing director, NCP. “Working with Terra Firma has allowed us to lower our carbon emissions and manage long-term energy costs more effectively. It’s a major step in building a more resilient and sustainable future for our operations.”

“As South Africa’s energy transition accelerates, more large energy users in complex industrial sectors are turning to onsite renewable systems to meet their cost and sustainability targets,” said Grant Berndsen, CEO, Terra Firma.

“Supporting a facility as vital as NCP’s, where uninterrupted operations are essential to public health, highlights the importance of getting these projects right. Integrating a 27 MWp solar system into a live chemical production site demands careful planning and collaboration, with the highest possible safety standards and processes. The success of this programme shows how renewables can be delivered effectively within such a high-stakes environment. It sets a benchmark for secure, compliant industrial decarbonisation.”

Vodafone boosts AI-driven power backup across Europe, Africa

Telecom and internet outages highlight just how dependent modern life is on uninterrupted digital connectivity. From GPS to mobile banking to emergency services, critical operations falter when networks fail. In response, Vodafone has accelerated its Enhanced Power initiative, a comprehensive programme designed to strengthen network resilience, extend power backup, and maintain vital connectivity for emergency and critical online services across Europe and Africa

Boosting AI and backup power

The increasing frequency of climate-related disasters and grid instability underscores the urgent need for resilient communications infrastructure for emergency services. Power outages caused by floods, wildfires, earthquakes, or blackouts can affect local, regional, or national areas. Though prolonged outages remain rare in Europe, last summer’s extreme weather alone is expected to cost the EU economy €126 billion by 2029.

The Enhanced Power initiative was fast-tracked following a major blackout in April 2025, which disrupted essential services including telecoms, transportation, and banking in Portugal and parts of Spain and France. At the outage’s peak, about 60% of Portuguese mobile users experienced connectivity loss or difficulties.

Vodafone’s programme aims to strengthen more than 10,000 critical mobile infrastructure sites supporting emergency services across Europe, beginning with Portugal and rolling out across Vodafone’s European markets over the next two years. The initiative combines existing temporary backup systems with AI-powered software to predict, control, and optimise backup power. Solutions are designed to handle outages depending on severity and scale, while also reducing CO2 emissions.

Local, regional, and national response capabilities

For localised outages affecting up to ten mobile sites, Vodafone will continue to deploy portable solutions such as Cells on Wheels (COW), complemented by the Instant Network Emergency Response (INER) programme. INER, active since 2012, provides free Wi-Fi and phone charging stations during disaster relief efforts and has supported 28 disasters worldwide, most recently Hurricane Melissa in Jamaica.

For larger regional outages impacting dozens or hundreds of sites, Vodafone deploys temporary and backup units alongside its AI-controlled Adaptive Power Backup system, which remotely extends base station battery duration, potentially doubling backup times.

Vodafone has also developed contingency plans for national or cross-border blackouts. Over 10,000 essential radio and backhaul access sites across Europe, including hospitals, government offices, airports, and transport hubs, will be equipped with at least four hours of backup power, while core mobile sites (over 400 data centres and backbone facilities) are guaranteed 72 hours of power or diesel generator refuelling within 48 hours. Aggregation sites, critical for routing customer data, are ensured a minimum of four hours’ backup.

Vodafone is exploring further resilience options by connecting emergency responders’ smartphones and other cellular devices via satellite even in extreme conditions.

AI to the rescue

Vodafone has launched its AI-driven Adaptive Power Backup service in Greece, with trials ongoing in Turkey before broader deployment in 2026. The system predicts outages and optimises energy usage, nearly doubling backup duration and keeping emergency services connected three times longer than industry standards. Non-essential equipment is remotely powered down or placed in low-energy “cell sleep mode,” while crucial communication channels remain operational.

AI adoption also reduces the capital needed for additional backup batteries, which would otherwise divert resources from network upgrades. Ofcom estimates that mandating four-hour backup at all UK telecom sites would require £2.2–4.4 billion (€2.6–5.2 billion), with similar costs expected across Europe. Vodafone is exploring collaboration with other operators and electricity providers, pooling resources to participate in electricity markets and using Virtual Power Plant services, enabling revenue generation from idle capacity. Government incentives are needed to drive wider adoption.

Africa focus

Vodacom, Vodafone’s African business, leverages AI to address challenges posed by frequent load-shedding. Its AI-on-the-edge solution prioritises energy sources, reduces diesel runtime, and ensures base stations operate on the most cost-efficient energy source without compromising availability. Initial results show a 10% – 15% reduction in diesel use, lower operational costs, fewer site visits, and improved customer experience.

Aligned with European frameworks

Vodafone’s resilience programme aligns with EU cybersecurity and infrastructure protection frameworks. Vodafone seeks to collaborate with Brussels and national authorities to ensure compliance, speed implementation, and explore co-funding opportunities. Operators alone cannot shoulder the burden, government support through funding and policy alignment is critical to sustain and expand infrastructure, ensuring Europe’s digital and telecom sectors remain resilient during major outages.

In a project engineered and executed by the Swiss-based Mitrelli Group, Angola has inaugurated the Quibala substation, the ninth and final substation to be delivered under the Sumbe-Gabela-Waco Kungo (SGWK) energy corridor

This milestone builds on earlier phases that added six substations and more than 600 km of overhead transmission lines (OHL) reaching up to 220 kV.

Together, this growing infrastructure forms the backbone of the SGWK corridor, improving the lives of 2.3 million people across the Cuanza Sul province, fuelling economic growth and industrialisation across the heart of the country.

The newly inaugurated Quibala 220/60 kV and 60/30 kV substation in Cuanza Sul Province will deliver reliable, renewable energy, adding 335 MW of available power to support industries, enhance public services and improve daily life across the region, a Mitrelli statement read.

It added that theconstruction of the substations has already created 900 direct jobs, with broader energy access expected to stimulate an additional 12,000 jobs across multiple sectors.

It also forms part of a broader, regional transformation with Mitrelli, in partnership with US-based energy investor HYDRO-LINK, advancing a landmark 1,150 km cross-border transmission corridor to link Angola and the Democratic Republic of Congo (DRC).

“This project will enable Angola’s renewable energy surplus, primarily from hydropower, to reach the DRC’s mineral-rich Copperbelt,” the Mitrelli statement noted.

“It represents a crucial step toward regional energy integration, improving grid stability, unlocking cross-border trade and strengthening energy security across Africa.”

Beyond residential and industrial use, the substations also support Angola’s agriculture and agri-processing sectors, critical pillars of its export diversification strategy.

Reliable electricity boosts production, reduces post-harvest losses, and expands cold storage capacity.

Rodrigo Manso, CEO, Mitrelli, also said that the transition to grid-connected, renewable power is expected to reduce dependence on diesel generators, cutting CO2 emissions by an estimated 392,000 cubic metres per year — the equivalent of generating 335 MW through fossil fuels.

“We are proud to stand alongside the Angolan government in expanding energy access as a foundation for inclusive national development,” said Manso.

“These projects drive economic growth, support businesses, and create jobs. The inauguration of the Quibala substation reflects Angola’s commitment to sustained progress. By combining global expertise with deep local knowledge, we’re helping build a more connected, self-sufficient, and prosperous future.”
