From forecast to field.
One technical partner across the energy project lifecycle.
From market intelligence and grid studies to integration, safety and protection. Our engineers combine digital analytics with hands-on field work, so the same team that models your grid can audit and protect it.
Why Sustains Energy
Built for decisions that move megawatts, and the people who keep them safe.
Most projects hand off between an analytics firm, a grid consultant and a site auditor. We cover all three, so assumptions carry through from the first forecast to the last relay setting.
One partner, full lifecycle
The same engagement can move from a price forecast to a grid-connection study to a site safety audit without a handoff.
Desk and field
Digital models in PSS®E, ETAP and PowerFactory, backed by on-site thermography, earthing and insulation testing.
Methods named on the page
Every deliverable states the model, the standard and the assumptions: ISO 50001, GHG Protocol, NFPA 70E and the rest.
Services
Six services. One technical partner.
Our work sits in two groups. Most engagements draw on both.
Digital Analytics & Grid Engineering
Markets · Models · SystemsPower System Planning & Grid Studies
Load flow, short circuit, stability and hosting-capacity studies for an inverter-dominated grid.
ETAP · PSCAD · PowerFactory · GridPath · PVsyst
Electricity Price Forecasting
Day-ahead and intraday probabilistic forecasts with P10 / P50 / P90 price ranges.
XGBoost · LSTM · ARIMA
Energy Resource Optimization
Dispatch, storage and hybrid co-optimisation that stack revenue and respect battery health.
Pyomo · Gurobi · HOMER Pro
Field Audits & Protection Engineering
Assets · Compliance · ReliabilityEnergy & Carbon Audit
Facility audits, GHG inventories and ISO 50001 roadmaps that cut energy cost and emissions.
ISO 50001 · GHG Protocol
Electrical Safety Audit
Compliance checks, thermography, and earthing and insulation testing to reduce risk on site.
NFPA 70E · IR Thermography
Relay Coordination & Protection Studies
Fault-current analysis, TCC coordination and relay parametrisation that keep faults contained.
ABB · Siemens · SEL
Technical insight. Real-world impact.
Sustains Build
Energy engineers who also ship software.
Sustains.ai builds web apps and APIs. Sustains Energy brings the grid, market and standards knowledge. So a study doesn’t have to end as a PDF.
01 Study
Day-ahead price study · IEX
| P90 | 8.60 |
| P50 | 6.74 |
| P10 | 5.26 |
The analysis, documented and defensible.
02 App
The same model, live for your team.
03 API
{
"hour": "19:00",
"unit": "INR/kWh",
"p10": 5.26,
"p50": 6.74,
"p90": 8.60
}The same numbers, inside your systems.
Domain-first data models
Buses, feeders, tariffs, scopes and relay settings are first-class objects, not columns in a spreadsheet.
Production APIs
Forecasts, study results and audit findings delivered as versioned endpoints or scheduled feeds.
Apps your operators use
Web dashboards and field apps built around the decision, by the engineers who did the study.
Insights
Research notes from our analyst desk.
We publish on the methods, markets, and policy questions that drive client work, from price forecasting to chokepoint risk.
Engagement
Planning, connecting or optimising an energy project?
Let’s solve the technical challenge. We work with utilities, IPPs, developers, industrial and commercial facilities, and EPC contractors. Tell us the decision or the site. We’ll tell you the studies, tests and team we’d bring.
