Portsmouth Marine Terminal (offshore wind staging redevelopment) · Transition modelFACILITY

As a 116-hectare marine terminal being redeveloped for offshore wind staging, the site's dominant dependencies are coastal/marine infrastructure and grid electricity rather than freshwater; baseline water stress is Low-Medium (BWS 1.14, label "Low - Medium (10-20%)") in the North Atlantic watershed, with overall physical risk scored Low at 0.88. The main present-state impact driver is Scope 2 emissions intensity, currently at the observed 2025 US grid value of 384.4 gCO2/kWh (Ember Yearly Electricity 2025). Coastal flood exposure (score 1.11) is the most relevant location-specific physical pressure given the terminal's waterfront position in Portsmouth, VA, though it remains within the Low overall risk band alongside a moderate drought score of 1.91.

By 2030, the IEA WEO 2024 STEPS horizon projects grid intensity falling to 220 gCO2/kWh, more than a 40% reduction from observed 2025 levels, meaningfully lowering Scope 2 exposure for terminal operations and any electrified port/staging equipment. Water-related forward horizons (2030/2050/2080 wd_future_score, ws_future_score, and 2080 labels) are not populated in this dataset, so no directional signal on future water stress or drought escalation can be cited; this is a data gap rather than an assessed stable outlook.

The grid decarbonisation trajectory continues to an 80 gCO2/kWh horizon by 2050, a ~79% reduction from the 2025 observed baseline, effectively de-risking the site's Scope 2 profile as the offshore wind staging function scales. Residual physical risk centers on coastal flooding given the site's tidal/marine location; absent 2080 water-stress and flood horizon data, this remains a monitoring item rather than a quantified long-term threat.
