Before Derapi, we were screen-scraping PGE's interconnect portal and manually entering AHJ requirements into spreadsheets. Now our site screening tool queries Derapi and returns a full go/no-go package in under two seconds.

Who uses Derapi
Engineering teams across the DER ecosystem
Solar EPC Software
Verdant Site Engineering
6-person engineering team. Previously scraped PG&E's interconnect portal manually. Now runs automated site go/no-go screening via Derapi — from 3 days to under 2 seconds per site. Screens 10x the volume with the same headcount.
EV Fleet Software
Ampere Mobility
Fleet software company, 12-person team. Replaced a weekly NREL irradiance ETL job with Derapi's /v1/solar/irradiance endpoint. Eliminated one full day of maintenance per week; shipping grid congestion-informed smart charging using Derapi's 15-minute signals.
Battery Optimization
Torchbear Energy
Early-stage battery dispatch optimization platform. Uses Derapi's capacity headroom endpoint to calculate economic dispatch signals in real time — queries run at sub-200ms p95 against live grid data, no internal SCADA feed required.
Solar Project Finance
Harrowfield Capital
Project finance firm with a growing solar underwriting book. Previously waited 2 weeks per deal for developer-supplied site data. Integrated Derapi into their underwriting tool; deal teams now pull interconnect queue status and irradiance actuals in the same afternoon as site identification.
Grid Analytics
Ironoak Grid Analytics
Distributed load forecasting platform covering 12 utility territories. Previously maintained 12 separate ETL pipelines — one per utility — each with its own schema and refresh schedule. Consolidated to a single Derapi integration with a consistent response schema across all territories.
EV Infrastructure
Waypoint Charge
EVSE siting and deployment platform, 8-person team. Uses Derapi's grid capacity headroom and V2G eligibility endpoints to rank candidate sites before any utility engagement. Replaced 6 months of planned custom data engineering with a Sandbox-to-Production upgrade in one sprint.
In their words
What engineering teams say
Derapi saved us three months of data pipeline work. The irradiance endpoint alone replaced a whole ETL job we had running on NREL data.
We cover 12 different utilities in our load forecasting tool. Before Derapi, each utility integration was a separate project. Now it's one API call with a consistent schema. The DX is excellent.
Solar deal underwriting requires the same interconnect and irradiance data a developer would gather in due diligence. We used to wait 10-14 days for that data. With Derapi in our underwriting tool, we run those pulls ourselves during initial screening — before we've even called the developer. That's a fundamental change in how we work.
