Overview
Sikkim is a small Himalayan state in India's Eastern Region (ER) grid zone, drawing its generation almost entirely from run-of-river hydropower. The headline figure is unambiguous: as of 2026-05-01, 100.0% of Sikkim's generation mix is classified as renewable energy. This makes it one of the few states in the country where fossil-fuel generation registers zero in the measured fuel-mix slice. Its carbon intensity averaged 24.1 gCO2/kWh over the recent ~48h window, a figure that reflects residual grid-import emissions rather than any in-state thermal generation. Peak supply reliability is strong: the p95 peak deficit stands at 0.0% (as of 2026-04-23 PSP series), indicating that peak demand has been consistently met across the measured distribution. The state's grid footprint is small, and real-time demand telemetry is not available via current Atlas feeds, limiting granular load analysis. Open-access charge data is similarly unavailable. The picture that emerges is of a hydro-dominated micro-grid with negligible carbon intensity and no reported peak shortage, operating within the ER pool.
Demand & Supply
Sikkim's generation mix, as captured in the two fuel-mix slices available, is 100.0% renewable—driven by run-of-river hydropower fed by Himalayan river systems. The recent ~48h window delta in RE share is 0.0 pp, indicating no measurable compositional shift in the generation mix between 2026-04-29T03:00 and 2026-05-01T00:00. This stability is consistent with baseload hydro operation rather than variable-output renewables such as wind or solar. Real-time demand in MW is not available for Sikkim; the Atlas SLDC feed does not currently cover this state, so absolute load figures cannot be cited. What the POSOCO PSP series does confirm is that the p95 peak deficit over the tracked daily history (23 data points, as of 2026-04-23) is 0.0%, meaning peak shortfall has not exceeded the measurement threshold at the 95th percentile. This implies that Sikkim's generation and/or contracted import entitlements within the ER grid have been sufficient to cover peak demand. Multi-year demand CAGR is not yet computable; the Atlas platform does not expose a long-term aggregator beyond the ~48h real-time window, so demand growth trajectory cannot be quantified from available data. IEX DAM prices for the ER zone are also unavailable due to an empty upstream feed.
RE & Transition
Sikkim's RE share at the latest measured hour (2026-05-01T00:00) is 100.0%, with a 0.0 pp recent-window delta over the ~48h window ending at that timestamp. This is not a multi-year trend—it reflects the state of the fuel mix within a discrete short window; no long-term aggregator is currently integrated into Atlas, so directional claims beyond this window cannot be made from available data. The average carbon intensity over the same ~48h window is 24.1 gCO2/kWh. For context, this residual intensity likely reflects the emissions factor applied to any grid-balancing imports from the ER pool rather than in-state combustion, given the 100.0% RE generation reading. RPO compliance data is not yet integrated (IEA-58); Sikkim's formal obligation fulfilment against state RPO targets cannot be assessed from current feeds. Similarly, transmission ATC data (IEA-56) is absent, preventing any assessment of curtailment or evacuation constraints that could limit effective RE delivery despite a nominally full-RE mix. The transition posture, on the basis of available metrics alone, is one of near-complete decarbonisation of in-state generation, with residual emissions confined to import-side grid carbon.
DISCOM Health
The two DISCOM health proxies available for Sikkim are the peak deficit p95 (0.0% as of 2026-04-23) and the open-access charge stack. On peak reliability, the 0.0% p95 figure across 23 daily PSP observations indicates that the distribution utility has not recorded material peak shortfalls in the tracked period—a positive operational signal for a small-state DISCOM. Open-access charges (CSS, wheeling, transmission, losses at HT voltage) are not available for Sikkim; the Atlas OA endpoint does not return data for this state, so the cost-of-power signal for industrial open-access consumers cannot be quantified. AT&C losses—the primary indicator of DISCOM commercial and technical efficiency—are not yet integrated (IEA-57, UDAY dataset), leaving the financial health of the distribution utility unassessable from current data. Residential tariff levels are similarly unavailable; the Atlas tariff endpoint requires an API key not yet provisioned. DAM price (a proxy for marginal procurement cost) is also absent. In aggregate: reliability looks adequate on the p95 metric, but the absence of AT&C loss, tariff, and OA charge data means a comprehensive DISCOM health assessment is not possible with current feeds.
Outlook
On a 1-3 year horizon, Sikkim's structural position is defined by three available data points: 100.0% RE share, 24.1 gCO2/kWh average carbon intensity, and 0.0% p95 peak deficit. The state has no apparent near-term pressure on peak supply adequacy based on the POSOCO PSP series. The primary forward risk is data opacity: without AT&C loss figures (IEA-57), DISCOM financial trajectory is opaque; without RPO compliance data (IEA-58), regulatory standing cannot be confirmed; without multi-year demand CAGR, load growth planning is not supportable from Atlas feeds. The 24.1 gCO2/kWh carbon intensity figure suggests residual import-side emissions remain—reducing this further would require either tighter ER grid decarbonisation or backstop storage to reduce import dependency during low-hydro periods. Seasonal hydro variability is a structural exposure that the current ~48h window cannot capture. Investors and policy advisors should treat the 0.0 pp recent-window RE delta as a snapshot of baseload hydro stability, not as evidence of stagnation or growth. Integrating the missing Atlas endpoints (IEA-56 through IEA-59, tariff API key, DAM feed) is a prerequisite for any actionable financial or regulatory assessment.
