Utilities unite to tackle grid supply chain challenges

Global utilities and leading power equipment manufacturers have united to address escalating bottlenecks within grid supply chains.
In a joint statement released during London Climate Action Week, industry leaders outlined steps to harmonise fragmented equipment standards and provide enhanced demand visibility, aiming to de-risk international procurement.
By 2030, Utilities for Net Zero Alliance (UNEZA) members will require nearly 90,000 kilometres of transmission cable; enough to wrap around the Earth over twice, alongside 273 high-voltage transformers, 12,000 medium- and low-voltage transformers, and 77 substations.
These requirements severely eclipse current manufacturing capacities, with transformer wait times now exceeding three years. Addressing these material constraints is critical to maintaining the pace of global grid expansion.
Co-led by UK utility SSE and Abu Dhabi-based TAQA, UNEZA operates under the guidance of the International Renewable Energy Agency (IRENA) and the UN Climate Change High-Level Champions, working alongside the UK Government-led Global Clean Power Alliance (GCPA).
UK Climate Minister Katie White stated: “This call from the Utilities for Net Zero Alliance shows that, by working with industry, governments can stop tying themselves in knots and start delivering the infrastructure needed to meet global demand – enough cable to wrap around the Earth more than twice. Through partnerships like the Global Clean Power Alliance, Britain is tackling long-standing barriers to clean energy. That will help us deliver the clean power mission, lower bills for good, and support other countries to reduce emissions and accelerate their own transition.”
Khalifa Al Mheiri, Chief Strategy & Investment Officer at TAQA Transmission, said: "As a utility investing in the next generation of electricity networks, TAQA recognises that delivering the energy transition at the pace the world requires depends not only on investment, but on our ability to strengthen and modernise global supply chains. Through UNEZA, utilities are taking practical action to improve coordination, harmonise technical approaches and explore pooled procurement models that provide greater certainty for suppliers while helping utilities deliver critical infrastructure faster, more efficiently and at lower cost. Collaboration across the value chain will be fundamental to building resilient electricity systems that support long-term energy security and net-zero ambitions.”
Glenn Barber, Director of Corporate Affairs at SSE, said: “We know from our experience in the UK that long-term visibility of demand is vital. It gives supply chain partners the certainty they need to invest in the manufacturing capacity and technical innovation needed to meet the demands of a monumental global energy transition. By bringing global utilities and supply chain partners together, UNEZA is not only helping to provide that visibility but tackling the practical barriers to supply chain development. The focus at London Climate Week on electrification of demand is welcome and necessary; at the same time, electrification will only be possible if grids can keep pace and the steps outlined today can plan an important role in that.”
Francesco La Camera, Director-General of IRENA, said: “We have spent the past decade proving that renewables can be deployed at scale. That case is made. The challenge now is ensuring grids and supply chains keep pace to deliver clean power reliably to homes, industries and communities. As electrification takes center stage in the next phase of the transition, with IRENA calling for a global electrification target of 35% by 2035, resilient supply chains will be essential. Initiatives such as the Utilities for Net Zero Alliance and the Global Clean Power Alliance show the value of governments, utilities and industry working together to accelerate progress while enhancing energy security and system resilience.”
Following a roundtable co-hosted with the GCPA, the alliance underscored massive financial commitments. At COP30, UNEZA members raised their collective annual investment target for renewables, grids, and storage from USD 117 billion to USD 148 billion. Overall clean energy investments between COP28 and 2030 are on course to exceed USD 1 trillion.
To secure supply chain resilience, UNEZA launched a Delivery Mechanism focused on pooled procurement. Members committed to three priority actions: providing annual demand signals to spur capacity growth, advancing harmonised equipment standards to improve interoperability, and scaling coordinated procurement. Now comprising 85 member organisations, UNEZA will continue developing this supply chain roadmap ahead of COP31, driving practical action to build robust electricity systems globally.
