Modelling Support

Provide modelling support particularly for high importance and urgent projects. Expertise in software development, energy markets and advanced probabilistic modelling allow for support in a variety of modelling roles.

State of the Art Uncertainty (SotA) and Probabilistic Energy Modelling

Support the development of SoTA energy models either in bespoke optimisation or in commercial software such as Energy Examplar’s PLEXOS. Current SotA industry models are:

Large scale Monte-Carlo models

Stochastic models (monolithic and with Stochastic Dual Dynamic Programming)

Analytics Development

Maximising insights from datasets (inputs and outputs) based on industry best practice and SoTA analytics in particular optimisation models.

Workflow Automation

Improving efficiency of modelling workflows using best practices energy market modelling. These may include:

Modelling lifecycle management

Data management

Workflow Orchestration

Workflow automation

Unit Test and Anomaly Detection

Technical Skills Development

Provide training in the following areas:

Energy Market Modelling

Mixed-Integer and Linear Programming

Uncertainty Modelling

Research Service (Innovation)

Development of innovative proof-of-concept models. Identification of state of the art models and innovative research that can be directly applicable to solve modelling issues. These proof-of-concept models bridge the gap between:

Purely academic models, which may not be practical in industry or a client's requirements as its specification / assumptions are too restrictive to describe real world scenarios.

Standard industry models, which may suffer from known issues such as exponentially exploding computational complexity.

We focus on a delicate balance, a Nash-equilibrium, between the purely analytical elegance of academic models and the practicality of models to solve urgent and important decision problems.
