SASEA™
SAS Energy Analyst
Your energy analyst
never sleeps.
Every source. One grid. The load that is redrawing it. Gas, nuclear, coal, wind, solar and battery storage — decades of history and live feeds — through to the datacenters turning that power into compute. Sourced, timestamped answers in seconds, not hours.
Models, not guesses. 24 months of supply, demand and storage forecasts — the SASEA BRAIN™ model layer — run beside live generation across every fuel on a Supabase-native data layer. Ask the questions that matter — SASEA runs the models that answer.
EIA · FRED · NOAA · NASA POWER · Baker Hughes · NRC · GFS · ECMWF — all connected, all real-time
Not another chatbot.
SASEA doesn't guess. It draws on a curated knowledge base on the Claude.ai platform, experiential intel from a 30-year industry veteran, heaps of historical data, and live API feeds. Right data. Right math. Right quick.
Live API Data
EIA, FRED, NOAA — real numbers, not vibes. Every table is sourced and timestamped.
NWP Weather Models
GFS + ECMWF forecasts piped straight into degree day math. 199-city weighted.
Full S&D Balance
Production, storage, demand, imports, power burn — the complete picture in one conversation.
30 Years of Market Expertise
Developed by a veteran energy-market professional.
One analyst. The whole energy complex.
SASEA started in natural gas and did not stop there. Each domain below is queried the same way — plain language, sourced numbers, timestamped.
Natural Gas
Dig DeepProduction, storage, demand, pipeline flows, LNG, and power burn — plus the V17 storage forecast running 24 months out.
Renewables
Wind and solar generation across the balancing authorities, with the weekly history behind it — sourced from EIA-930 and reconciled against the plant-level fleet.
Battery Storage (BESS)
The full operating US battery fleet — every unit, by state, balancing authority, and operator. Refreshed monthly from EIA-860M.
Datacenters & Compute
Named sites and committed capacity, tracked against the corridors where load actually shows up as generation. The in-app Knowledge Hub is the resource behind it — the buildout story, where the sites are, the power regions they sit in, and the full methodology.
Energy Weather
GFS and ECMWF runs driving 199-city population-weighted degree days by census division — the demand signal underneath every gas and power number on the platform.
European Gas & Power
Coming SoonTTF and NBP curves alongside continental power. In development.
