for key energy actors
The rapid evolution of energy systems and markets all over the world is driven by the need to decarbonize the economy, by combining high shares of renewables, energy efficiency, and the emergence of smart and flexible consumption-side technologies. The emerging paradigm has profound impacts on the role of regulators, governmental agencies, network operators and producers, who require more than ever support for an efficient and evidence-based decision making.
Optimizing the evolution of the energy systems taking into account sector coupling opportunities
Regulation & Market Design
Assessment of the social, environmental and economic impacts of energy/climate policies and measures
Cost-benefit analysis of infrastructure projects, such as interconnectors, P2G, storage, district heating, etc.
Due diligence of investment projects, risk analysis, analysis of revenue streams, including capacity value, ancillary services, etc.
The METIS project
Artelys has developed the METIS model for the European Commission’s Directorate-General for Energy. The tool allows for multi-energy systems modelling (electricity-gas-heat), at national or regional level, with an hourly time resolution. A collection of prospective studies have been carried out, on themes such as RES integration, the provision of flexibility, the synergies between the electricity and gas sectors (e.g. via power-to-gas).
PEPS4: CBA of electricity storage and power-to-gas options
Artelys has conducted a cost-benefit analysis of electricity storage and power-to-gas options. The potential contributions of these technologies to the provision of flexibility, the improvement of security of supply and to ancillary services have been simulated and analysed.
Annual production planning tools
CIE (Compagnie Ivoirienne d’électricité)
Artelys has set up for the Ivorian Electricity Company (Compagnie Ivoirienne d’Electricité) software for planning and optimization of the production of the Ivorian electricity system and the study of supply and demand balancing.
Trajectoires d’évolution du mix électrique 2020-2060
The study « Trajectoires d’évolution du mix électrique 2020-2060 » presents 7 contrasted evolutions of the French electricity mix, interconnected with neighbouring electricity systems. The electricity mixes are obtained by carrying out an economic optimisation of the trajectory of investments using Artelys Crystal Super Grid. This study is a first at the European level due to the size and the level of detail of the model (520 million optimisation variables, 670 million constraints).
Assessing Market Design options in 2030
Artelys experts have conducted the impact assessment of some of the policy proposals introduced by the “Clean Energy for all Europeans” package such as the coupling of intraday markets across Europe, the regional dimensioning of balancing reserves, removal of priority dispatch, etc.
Renewable energy source support schemes
Swiss Federal Office of Energy
Artelys has evaluated the effect of different RES-e support schemes on the market penetration of a set of technologies (PV, wind turbines, run-of-the-river hydro, pump-storage hydro).
Artelys generated EOM price curves for different scenarios of the structure of the Swiss electricity sector for a set of climatic scenarios. The effect of RES-e support schemes was translated into additional revenues. Artelys then modeled the actors’ dynamics by investigating the decision-making process from an individual investor point of view. Artelys thereby was able to quantify the cost of reaching the Swiss environmental targets when taking the investors’ risk aversion into account.
Energy transition and capacity mechanisms
UFE & BDEW
Artelys has evaluated the impacts of introducing of either a coordinated or an uncoordinated capacity remuneration mechanism on security of supply. Commissioned by UFE and BDEW, two French and German power sector associations, this study focuses on the way capacity mechanisms can reduce the risks caused by climatic conditions the revenues of power producers, and impact their investment decisions.
Weather-driven revenue uncertainty for power producers and ways to mitigate it
This study provides an analysis of risks on revenues for peak flexibility assets and ways to mitigate them in a 2030-European scenario with a 27% share of renewable energy generation. Indeed, since variable renewable energy generation is driven by weather conditions, further flexibility is required to provide firm capacity during scarcity periods. Ensuring that flexibility assets can get sound revenues from the market is therefore key to guaranteeing an appropriate level of electricity supply. The study shows that peak flexibility assets experience high uncertainties on their annual revenues and that, whichever the risk mitigation mechanism chosen, cooperation is key to avoid massive overinvestments.
CBA of additional interconnections at French borders
Commission de Régulation de l’Energie
Artelys assessed the impact on social welfare of additional interconnectors at French borders, using market models. This particular study was commissioned by the French national regulatory authority (CRE) in order to assess the impacts of the evolution of the power mix on the benefits brought by interconnectors, and to understand the way the benefits are allocated by the market to consumers and producers.
Next : Development of software designing and simulating smart grids
Supported by ADEME, the French Environment & Energy Management Agency, the NEXT project aims at designing and developing a European reference software for the simulation and sizing of smart grids, integrating multiple flexibilities (flexibility of production and consumption, storage, multi-energy flexibility, fine tuning of the grid…).
Artelys is the leader of a team of partners comprising Gaz Électricité Grenoble (GEG, 6th electricity distribution company in France), the Laboratory of Electrical Engineering and Power Electronics (L2EP) from Lille, and the French National Institute for computer science and applied mathematics (INRIA).
Analysis of transmission costs disparities in the French electricity network
Commission de Régulation de l’Energie
The French regulator of electricity wished to investigate the interest and feasibility of introducing local injection tariffs for electricity. Artelys performed computations based on historical consumptions and productions on 21 regions of France and on an optimal power flow model, and assessed the disparities of regional injection costs (in €/MWh) on an adapted transportation network.
This analysis demonstrated the existence of non-negligible electricity transportation cost disparities between regions directly due to demand and generation location. A sensitivity analysis on additional generated scenarios (based on statistical methods and generation optimization) confirmed stability of computed costs disparities on several different climatic years.
Audit of CBA Analysis
Artelys has carried out a detailed audit of the cost-benefit analysis of a large network investment project on behalf of its promoters. In particular, we have checked the consistency of the clients’ methodology with European guidelines for such investments, provided comments on key aspects of the analysis, evaluated the validity of assumptions and of key results.
Evaluation of RES projects
Artelys helps investors evaluating the expected revenues of their RES projects. Relying on its expertise relative to the electricity sector and on Artelys Crystal Super Grid, Artelys evaluates the expected hourly prices and the capture price of RES projects from today to 2050 for several pathways of evolution of the electricity mix (RES deployment, fuel and CO2 prices, development of flexibility sources, etc.) and assesses country-specific risk factors that might affect the revenues of the RES projects using sensitivity analyses.
Evaluation of the potential for power-to-hydrogen
Artelys helps investors and authorities evaluating the potential for power-to-hydrogen in areas with important volumes of cheap electricity (e.g. areas with high RES capacities and low interconnection capacities). For that purpose, Artelys evaluates the opportunities of producing cheap and CO2-free hydrogen by modelling the electricity system and performing capacity expansion optimisations, taking into account the existing and projected hydrogen consumptions.
