Sustains Build
Energy software, built by energy engineers.
Sustains.ai develops web apps and APIs. Sustains Energy knows grids, markets and standards. Sustains Build is where the two meet: any of our studies can be delivered as software your team keeps using.
01 Study

The analysis, documented and defensible.
02 App
The same model, live for your team.

Why domain-first
Software that understands the energy system it serves.
Most software teams learn the domain on your project. We start from it.
We know what a P90 means
The people writing the code built the forecast, ran the load flow or did the audit. Nothing is lost in a handoff to a generic dev shop.
The data model knows a bus from a feeder
Network topology, tariffs, revenue stacks and relay curves are modelled as what they are, so the software stays correct as the system changes.
Standards built in
ISO 50001, the GHG Protocol and NFPA 70E become structured fields and checks, not free-text notes at the end of a report.
What we can build
One interface for every service.
Six examples, one per service. Each is an illustrative interface built from sample data; yours is built around your decision and your data.
11 kV feeder, DER hosting capacity
Select a bus to see headroom.
- Headroom ≥ 3 MW
- 1.5 to 3 MW
- < 1.5 MW
Selected bus
B-07
PV headroom
0.6 MW
Status
Constrained
Limiting factor
Voltage rise
From Power System Planning & Grid Studies. Typical builds: Hosting-capacity map app, Contingency study runner.
IllustrativeHow we build
A modern, boring-in-a-good-way stack.
Proven open tooling your IT team can run, extend and audit.
- Python
- FastAPI
- Django
- PostgreSQL
- PyTorch
- Vue / Nuxt
- REST APIs
- Docker
- Cloud deploys
- 01
Study
We do the analysis and agree the method, inputs and outputs with your team.
- 02
Prototype
A working app or endpoint on your data, in weeks, so people can use it before it is final.
- 03
Production
Hardened, documented and deployed in your cloud or ours, with monitoring and an audit trail.
Engagement
Have a study that should be software?
Tell us the workflow. We’ll scope the app or API around it.
