PLANtoACT Task 2.1: Costs database of the PLANtoACT project

This repository presents the technology cost database compiled within the PLANtoACT project. PLANtoACT is a LIFE Programme–funded project (October 2025–September 2028), coordinated by EURAC with pilot regions and cities from France, Italy, Romania, Germany and Portugal, that develops, tests and promotes a stakeholder-driven, spatially detailed integrated energy planning approach to help European Local and Regional Authorities move from clean energy transition targets to coordinated, financed and implementable action. The dataset provides capital expenditure (CAPEX) learning curves for turnkey installations of different clean energy technologies, projected annually from 2020 to 2050. For each technology, cost estimates from multiple literature/model sources (e.g. IEA, IRENA, NREL, JRC, ETIP, SETIS) are collected side by side, together with an averaged value, to represent the expected decline in turnkey investment cost as deployed capacity and manufacturing experience increase over time. The data are intended to support techno-economic assessments and scenario modelling for the clean energy transition strategies developed in the PLANtoACT pilot regions. Structure README (first sheet): describes each technology tab, its full name, category, and a short technical description. One sheet per technology (e.g. PV rooftop, PV utility-scale, AgriPV, BIPV, Li-ion batteries residential/utility-scale, electrolyzer, fuel cell, onshore wind, offshore wind), each containing: year: 2020–2050, one column per literature/model source, and Average column used as the representative learning-curve value. Detailed descriptions of each technology are provided in the README sheet of the workbook and are not repeated here.
