National DC Policy 2025: 6 Metrics to Track

Single-window clearances, ESMA status, NBC updates and CLS access sound great. Here’s the scoreboard to know if builds actually speed up.
By bataSutra Editorial · September 11, 2025
In this piece:
  • 6 measurable metrics for policy follow-through
  • Benchmarks to watch at Centre vs State levels
  • Where bottlenecks move next (power, water, CLS)

The short

Clearances → Power (MW, RE%) → Resilience. Track single-window timelines, ESMA notifications, NBC adoption, CLS/ROW lead times, and water/WUE.

  • Clearances: Cut median approval timelines by ≥40% via single-window SLAs; publish state-wise hit rates.
  • Power: Track MW energised, % under firm RE PPAs, dual-feed availability, and outage minutes.
  • Resilience (ESMA): 10+ states to notify DCs as “essential service” with documented restoration priority.
  • Code (NBC): DC-specific classification adopted by ≥15 states; liquid-cooling/fire guidance clarified.
  • Connectivity: CLS approvals + ROW decisions in ≤60 days; new subsea landings monitored.
  • Water & ESG: Mandatory WUE reporting for >75% new MW; ≥50% treated/recycled water where feasible.

1) Clearance clock — from 30+ approvals to one window

Metric: Median days from application to “construction start” (site + building + fire + power + environmental) under the new single-window. Track by state.

Benchmark Year-1 target: cut median timeline by ≥40% vs 2023–24 baselines; publish state-wise SLAs and hit-rates monthly.

2) Power on tap — MW energised & renewable share

Metric: MW energised per quarter and share under firm renewable PPAs; time from substation readiness to energisation; outage minutes per quarter for DC parks.

Benchmark ≥60% RE-backed supply for new campuses; dual-feed substations; published outage SLAs and actuals.

3) ESMA “essential service” status — resilience in practice

Metric: Number of states formally notifying DCs as “essential service” under ESMA with documented restoration priority and exemptions during strikes/emergencies.

Benchmark 10+ states notified in Year-1; include power restoration priority and logistics exemptions in the text.

4) NBC recognition — code clarity for DC builds

Metric: Formal NBC classification and fire/life-safety annex specific to data centres adopted by states; # of permits citing the DC category.

Benchmark NBC-aligned DC occupancy adopted by 15+ states; fire-code equivalence for liquid cooling/higher densities clarified.

5) Connectivity — cable landing & backhaul access

Metric: New CLS approvals/year; average time for ILD/CLS co-location and ROW for backhaul; new subsea systems landed (IAX/IEX/2Africa Pearls etc.).

Benchmark 3+ CLS additions or expansions in two years; ROW decisions ≤60 days; co-lo pricing/SLAs published.

6) Water & sustainability — transparency and WUE

Metric: State-wise water extraction rules/charges applied to DCs; % of campuses with WUE disclosure; shift from evaporative to air/liquid-loop designs.

Benchmark Mandatory WUE reporting for >75% new MW; recycled/treated water share ≥50% where feasible.

Scorecard (what to publish quarterly)

Category Metric Why it matters
Clearances Median approval days; SLA adherence by state Predictability drops financing costs; reduces idle capex
Power MW energised; RE% of supply; outage minutes Campus ramp speed + carbon trajectory
ESMA # of states with ESMA notification; scope (power/logistics) Operational continuity and priority restoration
NBC States adopting DC-specific code/annex Removes interpretation delays, enables new cooling
Connectivity # CLS approvals; ILD/ROW lead times; new subsea landings Latency, route diversity, cost of bandwidth
Water & ESG WUE disclosure; recycled-water share; state charges License to operate; resilience in heat/drought

What good looks like in 12 months

  • Two new coastal CLSs online and ROW timelines under 60 days.
  • Median single-window approval timelines cut by ~40% across top DC states.
  • At least four parks formally under ESMA with documented restoration priority.
  • DC-specific NBC adoption across a majority of metros; liquid-cooling guidance clarified.
  • Quarterly public dashboards for power (MW, RE%), water (WUE), and outages.
