Open-TYNDP: Interfacing Open Energy System Planning with ENTSO-E Models and Contributing to TYNDP
Description
Release v0.9.1
This is an IT security patch release following a screening by ENTSO-E. It contains two minor bug fixes. The inputs differ from v0.9 only through a marginal (less than 0.2 % each) revision of Swiss road and domestic navigation oil demand in the new edition of the Swiss energy balances. Model results are not materially affected with respect to v0.9. Upgrading is recommended for all users of v0.9.
For complete technical details and implementation notes of this and any previous release, refer to the release note.

Notes
This repository introduces the open model dataset of the Open-TYNDP research and innovation project, which is a collaboration between Open Energy Transition (OET) and the European Network of Transmission System Operators for Electricity (ENTSO-E). The project's aim is to explore and consider the adoption of PyPSA in the Ten-Year Network Development Plan (TYNDP) by building a workflow based on PyPSA-Eur. It seeks to complement the tools currently used in the TYNDP cycles, especially for Scenario Building (SB) and Cost-Benefit Analysis (CBA). This approach is designed to enhance transparency and lower barriers to stakeholder participation in European energy planning. Beyond Europe, the project aspires to demonstrate the viability of open-source (OS) frameworks in energy planning, encouraging broader global adoption.
