Overview
Puducherry (UT, IEX Southern Region) is a small, import-dependent union territory whose generation footprint is structurally constrained by geography. As of the latest hourly slice (2026-05-01T01:00:00 UTC), renewables account for 25.4% of the territory's generation mix—a non-trivial share for an urban UT, but one that dropped sharply over the recent ~48h window. Carbon intensity averaged 612.0 gCO2/kWh over the same period, placing Puducherry firmly in the carbon-heavy half of Southern Region peers. The p95 peak deficit reading stands at 0.0% (as of 2026-04-23), indicating that peak demand has been met without recorded shortage at the 95th-percentile level. Real-time demand telemetry and open-access charge data are not available for this UT, which limits the depth of supply-side and cost-of-power analysis in this snapshot.
Demand & Supply
Puducherry's generation mix comprised four fuel-mix slices in the recent ~48h observation window. RE penetration stood at 25.4% of generation as of 2026-05-01T01:00:00 UTC. The recent ~48h window delta for RE share is −30.2 percentage points—a steep intra-window drawdown that most likely reflects a transition from high daytime solar output to a predominantly thermal or import-based supply posture during evening and nighttime hours; this is a short-window oscillation, not a multi-year structural trend. The p95 peak deficit is 0.0% (as of 2026-04-23 across the 23-point POSOCO PSP series), meaning the UT met its peak demand obligation without measurable shortage at the tail of the observed distribution. Real-time demand in MW is not available from live SLDC feeds for Puducherry; the 47-point demand history series in the chart data provides temporal context but does not yield a current MW anchor. Multi-year demand CAGR and IEX DAM price data are not yet integrated, preventing forward-load and market-price benchmarking.
RE & Transition
At 25.4% RE share (latest hourly, 2026-05-01T01:00:00 UTC), Puducherry registers above zero but below the Southern Region's leading states in renewable penetration. The recent ~48h window delta of −30.2 pp signals a pronounced diurnal collapse in renewable generation—almost certainly solar-driven—confirming that the UT's RE contribution is highly time-of-day dependent and not firmed by storage or dispatchable green capacity. Average carbon intensity over the ~48h window is 612.0 gCO2/kWh, consistent with a mix dominated by coal-sourced grid imports when solar is not generating. This intensity level is characteristic of a high-thermal baseline, and absent battery storage or firm RE procurement, the off-peak carbon footprint is unlikely to improve materially in the short term. RPO compliance data are not yet integrated (IEA-58), so it is not possible to assess whether Puducherry is meeting its mandated renewable purchase obligations. Multi-year RE capacity addition CAGR is also not yet available from the Atlas long-term aggregator, limiting any assessment of the pace of transition.
DISCOM Health
The available metrics for DISCOM health are narrow. On the reliability side, the p95 peak deficit of 0.0% (POSOCO PSP, as of 2026-04-23) indicates that Puducherry's distribution entity has procured or accessed sufficient power to avoid peak shortfall at the tail level across the 23-observation series—a baseline pass on supply adequacy. Open-access charge stack data (CSS + wheeling + transmission + losses, HT voltage) are not available for this UT, removing the primary quantitative proxy for cost-of-power signals and OA economics. AT&C loss data (UDAY dataset, IEA-57) are not yet integrated, which is the single most important gap for assessing DISCOM financial health; without it, revenue leakage and collection efficiency cannot be benchmarked. Residential tariff data are also unavailable, as the Atlas tariff endpoint requires an API key not yet provisioned. The combination of these three gaps—AT&C losses, OA charge stack, and residential tariff—means DISCOM financial posture can only be described directionally from the peak deficit figure.
Outlook
Over a 1–3 year horizon, Puducherry's key structural challenge is the high carbon intensity of its off-peak supply (612.0 gCO2/kWh average over the recent ~48h window) combined with a renewable share that collapses by ~30 pp intra-day, reflecting the absence of firming capacity. The 0.0% p95 peak deficit confirms current supply adequacy but does not address the quality or cost of that supply. Priority actions suggested by available data: (1) firm the 25.4% RE share with behind-the-meter or grid-scale storage to reduce the diurnal carbon intensity spike; (2) once the AT&C loss endpoint (IEA-57) and residential tariff endpoint are provisioned, benchmark DISCOM financial health and identify subsidy rationalisation headroom; (3) integrate RPO compliance data (IEA-58) to determine whether the UT faces regulatory risk under MoP enforcement; (4) activate the IEX DAM price feed to quantify the cost of import dependency. Until these data gaps are closed, investment and policy decisions carry material informational risk.
