Every chart on Wattfeed is powered by structured, source-verified data. This page documents each dataset — its columns, date range, coverage, and data quality.
Daily energy demand (MU) for 35 states and UTs across all five regional grids. Primary input to the state demand heat maps, seasonal overlay charts, and day-of-year comparisons.
DatePunjabHaryanaRajasthanDelhiUttar Pradesh7 sparse industrial/ISTS columns excluded. Values in MU.
All-India and five-region daily maximum demand met (MW). Feeds the multi-region trend charts and diversity factor computation — the ratio that measures how synchronised regional peaks are.
DateNRWRSRERNERUsed to derive diversity factor: Σ(regional peaks) ÷ all-India peak.
Evening peak demand at 19:00 hrs for all five regions and India. Tracks the critical post-solar ramp period and gauges pressure on peaking and storage assets.
DateNRWRSRERNERA rising diversity factor indicates increasingly staggered regional peaks — positive for grid stability.
Daily peak demand, time of occurrence, and unmet shortage split across solar hours (06:00–18:00) and non-solar hours (18:00–06:00). Reveals structural load shifts driven by solar penetration.
DateSolar Peak Demand (MW)Solar Time of PeakSolar Shortage (MW)Non-Solar Peak Demand (MW)Non-Solar Time of PeakGrowing divergence between solar and non-solar peaks indicates rising flexibility requirements.
State, regional, and all-India monthly peak demand met, energy met, shortages, and load factor from 2011. The foundational long-run demand dataset powering trend and regional comparison charts.
YearMonthStateRegionPeak Demand Met (MW)Peak Shortage (MW)Covers 37 states/UTs + 5 regions + all-India. Three logical sub-tables: peak, energy, load factor.
96-slot (15-minute interval) all-India demand profile recorded on the maximum-demand day of each month. Enables intraday load shape analysis, morning ramp quantification, and peak-hour identification.
YearMonthDatePeak_MW00:0000:15Each record = one peak day with 96 demand readings. Currently covers 2019–2021 only.
Monthly electricity generation by fuel type at both sectoral (central / state / private) and regional (NR/WR/SR/ER/NER) levels. Core input to the generation mix and renewable share charts.
YearMonthRegion / SectorThermal (MU)Nuclear (MU)Hydro (MU)Two logical tables (sectoral and regional) combined. Excludes captive generation.
Monthly installed generation capacity by region and fuel type. Quantifies the structural transition from thermal to renewables in India's generation fleet over the past decade.
YearMonthRegionThermal (MW)Nuclear (MW)Hydro (MW)Does not include captive generation capacity. Source: CEA monthly installed capacity report.
Daily hydro, solar, and wind generation by all five regions and India. Three parallel datasets — enables variability analysis, curtailment tracking, and renewable ramp profiles.
DateNR (MU)WR (MU)SR (MU)ER (MU)NER (MU)Three separate sheets (hydro, solar, wind) merged at load time. Small gaps in early 2019.
Daily forced and planned outage capacity across thermal, hydro, and nuclear units. Quantifies how much capacity is unavailable each day and distinguishes unplanned from maintenance outages.
DateThermal Forced Outage (MW)Thermal Planned Outage (MW)Hydro Outage (MW)Nuclear Outage (MW)Total Outage (MW)Forced outage spikes often correlate with demand shortfalls. Key reliability indicator.
Daily frequency distribution statistics — time within the IEGC band, under-frequency excursions, average frequency, and min/max. The real-time barometer of demand-supply balance.
DateAvg Frequency (Hz)Time Within Band (min)Time Below 49.9Hz (min)Time Above 50.05Hz (min)Min Frequency (Hz)IEGC mandates 49.90–50.05 Hz. Deviations trigger Unscheduled Interchange (UI) mechanism charges.
Monthly and daily cross-border power flows with Bhutan, Nepal, Bangladesh, and Myanmar under bilateral and multilateral trading agreements. Tracks India's role as a regional power hub.
YearMonthCountryImport (MU)Export (MU)Net (MU)Daily granularity available for aggregate import/export totals (paired sheets).
Daily net power flow between India's five regional grids. Identifies surplus and deficit regions, inter-regional congestion, and the physical direction of bulk power movement.
DateNR Net (MU)WR Net (MU)SR Net (MU)ER Net (MU)NER Net (MU)Computed from scheduled inter-regional exchanges across tie lines. Used for congestion analysis.
Monthly collective Short Term Open Access statistics — total energy traded, number of transactions, average rates, and participant counts in the C-STOA window cleared through NLDC.

Monthly bilateral Short Term Open Access volumes by region. Reveals which grids dominate as buyers and sellers in the short-term bilateral power market outside of exchanges.
YearMonthRegionEnergy Traded (MU)No. of TransactionsB-STOA = Bilateral STOA. Excludes exchange-based and collective STOA volumes.
Monthly Renewable Energy Certificate issuance, redemption, and outstanding balance by technology type. Tracks the compliance market that supports India's Renewable Purchase Obligation framework.
