Texas Residential Load Profile (ERCOT)
Get the typical residential electricity load curve for any Texas weather zone — averaged from ERCOT's official residential load profiles, in 15-minute resolution. Returns hourly or monthly aggregated kWh by hour-of-day and month-of-year, peak demand, and annual total. Useful for solar designers, battery sizers, AI agents modeling 'what does a typical home in Houston use', and anyone building bill-projection or solar-savings tools without a real customer's meter data.
ERCOT publishes residential load profiles (15-minute kWh values) for each of its 8 weather zones, broken into 4 residential profile types:
| Profile | Customer type |
|---|---|
| RESHIWR | Residential heating with weather response (default — most common) |
| RESHIDG | Residential heating with distributed generation (solar homes) |
| RESHIPV | Residential heating with PV |
| RESHIWD | Residential without distributed generation |
These curves represent the typical home in a zone. They're the same curves Meter uses internally to model bill projections and solar savings when a real customer's Smart Meter Texas (SMT) data isn't yet available.
Inputs: Provide either a ZIP code (resolved to weather zone via ZIP-prefix → zone mapping) OR a weatherZone code directly. Optional profileType + year. The granularity flag controls payload size:
- monthly_hourly (default, 288 entries): typical kWh by month × hour
- monthly_totals (12 entries): just monthly kWh totals
- annual_hourly (8760 entries): full year of hourly averages
Why this exists:
- Solar designers need a typical load curve for every proposal — without it, "your panels will save you $X" estimates are guesswork
- Battery sizers need to know when in the day a home draws power
- AI agents modeling Texas electricity bills need a baseline shape when the user can't provide their own meter data
- Researchers and energy nerds compare zones (Houston vs DFW summer shapes are very different)
For real customer data, use pull_smt_interval_data (gives the actual home's usage, not the regional average). This tool is the "typical home" baseline; SMT is "this specific home."
