For the people rebuilding the grid · Powering the Global Energy Transition

Energy + electrical, in code.

Energy and electrical engineers who don’t just advise. We ship. Methods named on the page, models in production, and a SaaS platform for energy operators.

Why Sustains Energy

Built for energy decisions that move money or megawatts.

Generic consulting frameworks don’t price options on a volatile grid. We pair classical power-system rigor with modern data tooling, and we’re transparent about the methods we use.

Method-rich, not method-light

We name our models. ARIMA, LSTM, Transformers, RL, stochastic optimisation, Monte Carlo, and the reasons we picked one over another.

Domain depth across the value chain

Generation, T&D, storage, markets, regulation, finance. The same engagement can move from EMT studies to PPA structuring without a handoff.

Decisions, not decks

Outputs are calibrated to a specific bid, investment, regulatory filing, or planning decision, not a static report you’ll archive.

Services

Five practice areas. One coherent view of the energy system.

Engagements typically span more than one, because price risk, asset dispatch, grid stability, and financing decisions move together.

All services
01

Electricity Price Forecasting

Econometric and deep-learning models that mitigate price risk in day-ahead and real-time markets.

  • Day-ahead and intraday probabilistic forecasts
  • Hybrid econometric + deep-learning ensembles
  • Backtesting against ERCOT, NEM, IEX, EPEX, Nord Pool
02

Market Forecast Studies

Long-horizon outlooks on demand, supply, capacity, and regulatory shifts shaping power and fuel markets.

  • 2025–2035 capacity and generation outlooks
  • Tariff, subsidy, and carbon-policy scenario modelling
  • Cross-fuel views: power, gas (Henry Hub, TTF, JKM), coal
03

Energy Resource Optimization

Squeeze more value out of every asset, solar, wind, BESS, hybrid, or thermal, through data-driven dispatch.

  • BESS dispatch optimisation across stacked revenues
  • Hybrid solar+storage co-optimisation
  • Digital twins for PV strings and grid-forming inverters
04

Power System Analysis

Grid stability, reliability, and DER integration studies for an increasingly inverter-dominated grid.

  • Load-flow, short-circuit and dynamic stability studies
  • Hosting capacity and DER interconnection analysis
  • EMT studies for IBR-rich grids
05

Energy Project Finance

Funding strategy and financial structuring for energy infrastructure, from greenfield IPPs to retrofit upgrades.

  • Lender-grade DCF and project-finance models
  • Sensitivity and Monte Carlo analysis on price/CF risk
  • Capital stack design, debt, equity, mezzanine, tax equity

Insights
