Bainton Heath Electricity Substation · Transition modelFACILITY

As an HV substation, Bainton Heath's core dependency is grid/asset reliability rather than water or purchased energy consumption in the conventional sense — it is part of the delivery infrastructure itself. The site sits in a Low-Medium water stress area (BWS score 1.65, label "Low-Medium 10-20%") within the North Sea watershed, with overall physical risk scored Low (<25%, 0.64). Riverine flood score (1.82) and coastal flood score (2.80) are modest but non-trivial for asset resilience planning given the site's grid-critical function. The observed GB grid carbon intensity is 217.41 gCO2/kWh (2025, Ember), the relevant benchmark for any auxiliary power or Scope 2-adjacent exposure at the site.

The GB grid emissions trajectory is projected to hold near 100 gCO2/kWh by 2030 under IEA WEO 2024 STEPS — less than half the 2025 observed intensity — reflecting continued renewables build-out and reduced thermal generation. Water-related forward horizons (2030/2050/2080 for both water depletion and water stress) are not populated in this dataset, so no directional signal is available on shifting physical water risk at this location; current Low-Medium baseline stress should be treated as the reference point until updated. No flow-level data (energy, water withdrawal volumes) is recorded for this facility, limiting quantification of operational exposure.

By 2050, GB grid intensity is projected to fall further to 30 gCO2/kWh under STEPS, consistent with near-full decarbonisation of the national power system — a structural tailwind for any transition-linked emissions exposure tied to this asset. Residual physical risk at this site is dominated by coastal and riverine flood scores (2.80 and 1.82 respectively) rather than water scarcity, and with no long-horizon water stress/depletion labels provided, downstream flood and drought dynamics (drought score 3.29) remain the key watch items for asset resilience through mid-century.
