Energy networks as top economic bet: key project insights for civil engineers
Reviewed by Joe Ashwell

First reported on New Civil Engineer
30 Second Briefing
Investment in constructing energy infrastructure delivers the largest economic growth multiplier among infrastructure classes, according to new modelling by Boston Consulting Group. The analysis compares grid and transmission upgrades with sectors such as transport, water and social infrastructure, finding that spending on energy networks generates the highest indirect gains through supply-chain activity and productivity. For civil and geotechnical engineers, the findings strengthen the case for capital programmes focused on high-voltage transmission, distribution reinforcement and grid‑connection works for renewables.
Technical Brief
- For project pipelines, the work supports prioritising grid-connection civil works in constrained public capital budgets.
Our Take
Boston Consulting Group appears only sporadically in our 644-item Infrastructure category, so its involvement here signals that energy networks are being framed more as a macroeconomic productivity lever than as a conventional project-by-project capex decision.
Across the 1,760 tag-matched ‘Projects’ and ‘Sustainability’ pieces, most infrastructure coverage focuses on transport or water assets, so highlighting energy networks as the most economically beneficial suggests a reprioritisation case for grid and network upgrades in public investment pipelines.
For New Civil Engineer’s practitioner audience, BCG’s economic framing of energy networks is likely to feed directly into business cases and cost–benefit analyses, strengthening arguments for regulatory allowances and long-term network planning rather than short-term asset sweating.
