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 (transmission & distribution), storage, markets, regulation, finance. The same engagement can move from a grid stability study to a power purchase agreement 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.
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 (price ranges, not just single numbers)
- Hybrid econometric and deep-learning ensembles
- Backtesting against ERCOT (Texas), NEM (Australia), IEX (India), EPEX (Europe), and Nord Pool (Nordics)
Market Forecast Studies
Long-horizon outlooks on demand, supply, capacity, and regulatory shifts shaping power and fuel markets.
- 2025–2035 capacity and generation outlooks (how much of what gets built, where, and when)
- Tariff, subsidy, and carbon-policy scenario modelling
- Cross-fuel views across power, gas (Henry Hub US, TTF Europe, JKM Asia), and coal
Energy Resource Optimization
Squeeze more value out of every asset, solar, wind, BESS, hybrid, or thermal, through data-driven dispatch.
- BESS (battery energy storage system) dispatch optimisation across stacked revenues
- Hybrid solar + storage co-optimisation
- Digital twins for PV (photovoltaic) strings and grid-forming inverters
Power System Analysis
Grid stability, reliability, and DER integration studies for an increasingly inverter-dominated grid.
- Load-flow, short-circuit and dynamic stability studies (steady-state, fault, and post-disturbance behaviour)
- Hosting capacity and DER (distributed energy resource) interconnection analysis
- Demand–supply gap and MW / MWh / MVAR (power, energy, reactive power) assessments
Energy Project Finance
Funding strategy and financial structuring for energy infrastructure, from greenfield IPPs to retrofit upgrades.
- Lender-grade DCF (discounted cash flow) and project-finance models
- Sensitivity and Monte Carlo analysis on price and cash-flow risk
- Capital stack design across debt, equity, mezzanine, and tax equity
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.
The "Hormuz Chokepoint": A Systemic Stress Test for Energy Forecasting
The March 2026 Strait of Hormuz disruption is exposing the structural limits of ARIMA/LSTM-class models, and pushing EMS architecture toward graph-based and stochastic methods.
Beyond Efficiency: Turning Industrial Assets into Profit Centers with VPPs
How reinforcement-learning-driven Virtual Power Plants transform on-site BESS and solar from stranded costs into balance-sheet assets, with a Germany vs. India regulatory contrast.
Is Blockchain the Missing Link for a Resilient, Decentralized Grid?
Blockchain has crossed the buzzword threshold, P2P energy trading, smart-contract settlement, and microgrid platforms are now live deployments delivering measurable tariff savings.
