With the continued expansion of renewable energy, the electrification of transportation and heat, and the rapid growth of data centers to support AI, global demand for electricity is surging. Electricity grids require significant investment to meet this skyrocketing demand. According to Bloomberg New Energy Finance, grid spending is expected to reach $577 billion annually by 2027, up from an estimated $479 billion in 2025. Clean Edge’s 2026 Grid Market Map represents a selection of companies and organizations contributing to the grid across a range of sectors, from transmission & distribution manufacturers and data and software providers to grid enhancing technology innovators and energy storage players. This year we made a number of changes to the market map, including reclassifying players such as Eaton and GE Vernova; removing companies that went bankrupt or changed their business focus, including Sunnova and NGK Insulators; adding companies such as Bloom Energy and KEC International; and bolstering our NGO and trade group section, in particular by adding in European players such as the EU DSO and Eurelectric. As always, this is not an exhaustive list but a high-level survey of established and emerging players.
