Read NowDelhi (Union Territory, IEX Northern Region) draws power from a tightly integrated northern grid rather than from substantial in-territory generation. At 4,051 MW of live demand (as of 02:15 UTC, 01 Jun 2026), it represents one of India's most concentrated urban load centres. Renewable energy accounts for just 6.3% of the current generation mix — low even by NR standards — and the average carbon intensity over the recent ~48h window stands at 660.3 gCO2/kWh, consistent with a coal-heavy import profile. On the positive side, the p95 peak deficit registers at 0.0%, indicating that supply has been meeting peak demand reliably over the assessed period. AT&C losses across Delhi's three DISCOMs averaged 7.58% in FY23 (range: 6.00–9.18%), which is comparatively low nationally. The open-access charge stack at HT voltage is INR 0.98/kWh. RPO compliance is estimated at 20.8% (FY23, provisional). The territory's energy story is one of reliable supply and low distribution losses set against a low RE share and high carbon intensity.
Live demand at 02:15 UTC on 01 Jun 2026 stood at 4,051 MW. Delhi has no significant in-territory thermal generation base and relies predominantly on interstate allocations and bilateral/short-term power from the Northern Region pool. The current fuel mix reflects this dependence: renewable energy constitutes 6.3% of the generation slice as of 02:00 UTC on 01 Jun 2026, with the remainder attributable to coal and gas-based central-sector allocations. A recent-window RE share delta could not be computed — the endpoint returned null at both window endpoints — so directional movement within the ~48h window is unquantifiable at this time. The p95 peak deficit over the assessed period (as of 30 May 2026) is 0.0%, meaning that at the 95th percentile of daily peak conditions, Delhi experienced no measurable shortfall between peak demand and peak supply. This is a strong reliability signal for a UT with no captive thermal buffer. Transmission ATC/TTC data for Delhi is not yet available in the Atlas database, so corridor-level headroom cannot be assessed. The open-access charge stack at HT voltage is INR 0.98/kWh (as of 01 Apr 2025), representing the all-in cost of CSS, wheeling, transmission, and losses for eligible consumers sourcing power outside DISCOM supply.
Delhi's RE share in the current generation mix is 6.3% (as of 02:00 UTC, 01 Jun 2026). This is materially below the national trajectory implied by RPO schedules. RPO compliance for FY23 is provisionally estimated at 20.8% against DERC tariff order data — flagged as modelled rather than audited, and the upstream Atlas RPO compliance feed is not integrated; this figure should be treated as indicative. The average carbon intensity over the recent ~48h window is 660.3 gCO2/kWh, which is high and consistent with a generation mix dominated by coal-based central-sector draws. A within-window RE share trend could not be computed due to missing endpoint data; no directional claim is possible for the ~48h period. A multi-year demand CAGR is not yet available — the Atlas platform does not expose a long-term aggregator — so long-run trajectory against RPO targets cannot be benchmarked here. Delhi's transition posture is therefore characterised by: a low absolute RE share, an elevated carbon intensity, provisional RPO compliance data, and the absence of a verified long-term demand or generation trend series. Any assessment of transition pace relative to DERC-mandated RPO glide paths would require PFC/DERC audited annual data.
Delhi's three DISCOMs (BRPL, BYPL, TPDDL) reported a mean AT&C loss of 7.58% in FY23, with individual DISCOM losses ranging from 6.00% to 9.18% — among the lowest AT&C figures for any major Indian urban UT, reflecting sustained metering and collection investment over the prior decade. The p95 peak deficit of 0.0% (as of 30 May 2026) corroborates adequate procurement headroom relative to peak load. The open-access charge stack at HT voltage is INR 0.98/kWh (as of 01 Apr 2025), covering CSS, wheeling, transmission, and losses; this is the operative cost-of-power signal for industrial and C&I consumers considering OA arrangements. Two material data gaps limit the DISCOM health assessment: residential tariff data is unavailable because the Atlas tariff endpoint requires an API key not yet provisioned, and IEX DAM average prices are unavailable due to an empty upstream feed — preventing a tariff cost-of-supply comparison. Active subsidy or incentive scheme data is also absent from the Atlas database (IEA-59 pending). Transmission ATC/TTC is not yet integrated for Delhi.
Over a 1–3 year horizon, Delhi's core strength is supply reliability: a 0.0% p95 peak deficit and 7.58% mean AT&C losses provide a stable baseline for any demand growth scenario. The primary structural vulnerability is carbon intensity — at 660.3 gCO2/kWh, the import-heavy mix leaves Delhi exposed to any tightening of national RPO obligations or corporate green-power mandates. With RE share at 6.3% and provisional RPO compliance at 20.8% (FY23, modelled), the gap to near-term RPO targets is likely to widen unless DERC procures additional RE through bilateral or RE-certificate mechanisms. The OA charge of INR 0.98/kWh at HT offers C&I consumers a measurable cost of self-sourcing; whether this is competitive against DAM prices cannot be assessed until the IEX feed is restored. Three data integrations — residential tariff, IEX DAM price, and multi-year demand CAGR — are required before a fully quantified investment or household-level recommendation can be made. Priority actions for the UT: (1) accelerate DERC's rooftop solar and RE procurement pipeline to close the RE share gap; (2) restore Atlas IEX and tariff feeds to enable real-time cost benchmarking; (3) commission an independent AT&C audit to validate FY23 DISCOM figures ahead of the next tariff cycle.
