Overview
Andaman & Nicobar Islands (UT, IEX zone A1) is a geographically isolated archipelago operating outside the mainland synchronous grid. Its electricity system is a collection of island-level diesel-dominated microgrids, with renewable energy—primarily solar—supplementing diesel generation. As of 2026-05-01, RE constitutes 7.7% of the generation mix in the latest hourly slice, underscoring the system's continued structural dependence on fossil-fuel-based diesel generation. The UT's insularity means it has no interstate transmission interconnect, making it ineligible for conventional open-access markets and largely insulated from IEX DAM price signals. This also constrains the analytical coverage available from mainland POSOCO and Atlas feeds: peak deficit telemetry, real-time demand MW, carbon intensity, and open-access charge data are all unavailable for this UT. The two available metrics—RE share and its recent ~48h window delta—form the primary quantitative anchors for this snapshot.
Demand & Supply
Real-time demand telemetry (latest_demand_mw) is not available for Andaman & Nicobar Islands; the SLDC feed is not integrated into Atlas. Similarly, POSOCO PSP does not carry rows for this UT, so peak deficit p95 cannot be computed. The fuel-mix picture, derived from two hourly slices available in the Atlas feed, shows RE at 7.7% of generation as of 2026-05-01T01:00:00 UTC. The remaining ~92.3% is attributable to diesel and other thermal sources, consistent with the UT's island microgrid architecture where dispatchable diesel sets serve as the baseload and frequency-regulation backstop. The recent ~48h window delta for RE share is -21.98 percentage points—a sharp intra-window contraction, most plausibly reflecting reduced solar output due to time-of-day or weather variability across the observation window rather than any structural capacity change. No multi-year demand CAGR is available; the Atlas long-term aggregator is not yet integrated. IEX DAM prices are not applicable given the UT's off-grid status, and the upstream IEX feed is in any case empty.
RE & Transition
RE's 7.7% share of generation (as of 2026-05-01T01:00:00 UTC) reflects the current penetration of solar capacity across the island microgrids. However, the recent ~48h window delta of -21.98 pp signals significant intra-day and short-window variability—this is not a multi-year trend indicator and should not be interpreted as capacity regression. Carbon intensity data is not available for this UT; Atlas carbon-intensity rows are absent, so no gCO2/kWh figure can be cited. RPO compliance data is also not yet integrated (IEA-58), meaning it is not possible to assess whether the UT is meeting any notified renewable purchase obligations. The absence of a long-term demand CAGR aggregator (IEA not yet integrated) prevents projection of RE capacity adequacy against demand growth. The structural transition challenge for Andaman & Nicobar is the replacement of diesel generation with a combination of solar-plus-storage and, potentially, small-scale wind—a capital-intensive proposition for a UT with limited land mass, subsea cable constraints, and a small consumer base that limits internal revenue generation.
DISCOM Health
The DISCOM serving Andaman & Nicobar Islands (Electricity Department, A&N Administration) operates outside the conventional state DISCOM benchmarking framework. Open-access charge data (CSS, wheeling, transmission, losses) is not available for this UT—the island system has no open-access market. AT&C loss data from the UDAY dataset is not yet integrated into Atlas (IEA-57), so distribution efficiency cannot be quantified here. Residential tariff data is also unavailable; the Atlas tariff endpoint requires an API key not yet provisioned (IEA not yet integrated). Peak deficit p95 from POSOCO PSP carries no rows for this UT. The combined effect of these gaps is that DISCOM financial and operational health cannot be assessed quantitatively from current Atlas feeds. What can be inferred structurally: high diesel dependence implies elevated per-unit generation cost, and a small, geographically dispersed consumer base typically correlates with high distribution costs—but neither figure can be cited without integrated data.
Outlook
With RE at 7.7% of generation and structurally high diesel dependence, the 1–3 year priority for Andaman & Nicobar is expanding solar-plus-storage capacity across the larger island clusters (Port Blair, Neil, Havelock) to displace diesel and reduce fuel import risk. The -21.98 pp recent window delta in RE share illustrates the variability challenge: any RE scale-up must be paired with battery storage or demand-side flexibility to maintain island grid stability without diesel spinning reserve. The absence of AT&C loss, residential tariff, RPO compliance, and demand CAGR data (all not yet integrated) limits quantitative planning inputs from this snapshot. IEX DAM pricing is structurally inapplicable. The UT's case for central government capital support (under schemes such as DDUGJY or dedicated island electrification programmes) rests on its off-grid status and the national strategic importance of the archipelago—factors outside the scope of the current Atlas data but relevant to any investment or policy framing.
