GLOBAL ELECTRICITY INFRASTRUCTURE COST OVERRUN MARKET (2026 - 2030)

The Electricity Infrastructure Cost Overrun Market was valued at approximately USD 15 Billion in 2025 and is projected to reach a market size of around USD 27.60 Billion by the end of 2030. Over the forecast period of 2026-2030, the market is expected to grow at a CAGR of about 13%.

The Electricity Infrastructure Cost Overrun Market tracks how and why power projects exceed planned budgets across generation, transmission, and distribution systems globally. It covers cost deviations, risk patterns, and control mechanisms used by utilities, developers, and contractors. The focus is not electricity output, but financial performance gaps during project execution and delivery stages. It includes cost overruns across power generation, transmission, distribution, and renewable integration projects, along with services such as project control, risk advisory, EPC oversight, and digital monitoring. It excludes non-electric infrastructure, operational cost inefficiencies post-commissioning, and unrelated construction sectors that do not directly impact electricity infrastructure project budgets.

Since 2024, cost overruns have shifted from isolated execution issues to systemic risks driven by supply chain volatility, renewable integration complexity, and financing uncertainty. Projects now face multi-layered risks that interact, making traditional cost estimation models less reliable and harder to defend.

Buyers must evaluate cost overrun drivers, not just project size. Better decisions depend on identifying risk sources early and selecting the right control mechanisms.
