Sigma Research OÜ

Services

Engagements are structured around decision problems, not generic analytics packages, with production model implementations built in GAMS and CPLEX.

Portfolio Dispatch Across Interconnected Assets

Typical situation
Operators need coordinated dispatch across plants, storage, and interconnectors under changing demand and market signals.
Deliverables
Network-constrained dispatch model, nodal sensitivity analysis, and operator handover documentation.
Data required
Network topology, transfer limits, unit constraints, load forecasts, and market price trajectories.
Typical engagement
4-8 weeks from diagnostics to pilot-grade dispatch workflow.

Large-Scale Power Dispatch and Scheduling

Typical situation
Generation portfolios with mixed renewable and thermal assets face volatile prices, unit constraints, and emissions targets.
Deliverables
Unit commitment and dispatch optimization model (implemented with GAMS and CPLEX), scenario engine, and operator-facing scheduling outputs.
Data required
Asset characteristics, ramp/start-stop constraints, fuel and variable costs, demand profiles, and carbon factors.
Typical engagement
6-12 weeks from model design to production-ready scheduling workflow.

Generation Capacity and Reserve Planning

Typical situation
Reserve margins are maintained conservatively, increasing variable cost and curtailment risk.
Deliverables
Capacity planning model, reserve policy scenarios, and actionable operating recommendations.
Data required
Demand and renewable forecasts, outage assumptions, reserve requirements, and asset availability.
Typical engagement
3-6 week planning optimization projects.

Market and Emissions Scenario Decision Support

Typical situation
Fuel spreads, carbon prices, and renewable volatility create uncertainty in dispatch decisions.
Deliverables
Scenario engine for cost and emissions trade-offs, decision memo templates, and KPI framework built on GAMS and CPLEX model implementations.
Data required
Fuel and carbon price assumptions, bid strategy inputs, technical limits, and compliance constraints.
Typical engagement
2-4 week scoping with optional ongoing advisory.
