Regulated networks that move electricity, gas, water and heat, spanning national transmission systems, regional distribution, and the last-mile assets that connect end users. The most mature regulated-return asset class in infrastructure.
Energy & utility networks are the archetypal infrastructure asset: physical monopolies whose revenue is set by a regulator rather than a market. Across most of the class, value is earned on a regulated asset base: the regulator allows a return on invested capital, recovery of depreciation, an operating allowance and performance incentives, largely decoupling revenue from the volume flowing through the pipes and wires.
That makes these the most defensive, most rate-sensitive assets in infrastructure. The references below work through transmission, distribution and last-mile assets across electricity, gas, water and heat, each illustrated with real networks under genuinely different regulatory regimes.
