Energeia

Simulating electricity markets
energeia simula is a windows-based simulation tool that computes equilibrium outcomes in electricity wholesale markets

Using a sound oligopoly model
The simulations performed by energeia simula are based on an oligopoly model that reflects most important features of electricity markets. This model has been published in leading journals in economics:

Fabra, N. and Llobet, G. (2025) “Fossil Fuels and Renewable Energy: Mix or Match?”, Rand Journal of Economics

Fabra, N., Lacuesta, A. and Souza, M. (2020) “Degrowth versus Decoupling: Competing strategies for carbon abatement?European Economic Review.

De Frutos, M.A. and Fabra, N. (2012) “How to Allocate Forward Contracts: the case of electricity marketsEuropean Economic Review 56(3), 451-469.

Building counterfactuals to analyze effects
energeia simula is capable of predicting (static) equilibrium bidding behavior among generators under various scenarios

It allows to assessing the effects of (among others):

  •   Changes in market structure: mergers, divestitures, etc.
  •   Changes in market rules: contract obligations, emission rights, etc.

Assessing low-carbon investments

The new module allows to measure the market impact and assess the financial profitability of low-carbon projects, including renewable investments (solar, wind, solar thermal), energy storage, green hydrogen and data centres.
