Oak Hill · Transition modelFACILITY

The dominant physical dependency at Oak Hill is grid electricity, with the US grid observed at 384.4 gCO2/kWh (Ember 2025), making Scope 2 the likely primary GHG impact channel given the manufacturing asset type. Locally, water risk is Low across the board: baseline water stress (BWS) scores 0 (Low, <10%), overall water risk is 0.88 (Low, <25%), coastal flood risk is 0, and riverine flood risk is modest at 0.33. Drought score sits at 1.79 and untreated wastewater score at 0.88, both worth monitoring given the site's own asset-subtype flag as a "manufacturing (high water risk site)" — an internal designation that is not fully corroborated by the low external water-stress indicators shown here, and warrants reconciliation.

By 2030, the grid carbon intensity horizon (IEA WEO 2024 STEPS) drops to 220 gCO2/kWh, a roughly 43% reduction from the 2025 observed value, meaningfully de-risking the site's Scope 2 exposure without any operational change required. No forward water-stress (ws) or water-depletion (wd) horizon scores are populated for 2030, so the water-risk trajectory cannot be quantified at this horizon; today's Low ratings should be treated as the working baseline until horizon data is populated. The site is also flagged as a renewable power investment location, suggesting an active opportunity to accelerate decarbonisation ahead of grid-average trends.

By 2050 the grid horizon falls further to 80 gCO2/kWh, implying near-complete decarbonisation of purchased electricity under the STEPS trajectory — an 80%+ reduction versus 2025 — which would largely neutralize Scope 2 as a material impact category for this site. No 2080 grid or water horizon data is available, limiting visibility into residual long-run physical risk. Given current Low ratings on coastal and riverine flood and moderate drought/wastewater scores, residual physical risk appears manageable, but the unresolved "high water risk site" internal tag remains a data gap that should be closed before long-term risk is signed off.
