Norwegian energy community dataset: An electricity-hydrogen system with renewables, battery storage & hydrogen demand.

This paper presents the Norwegian Energy Community Dataset, developed to support modelling and optimization of integrated electricity-hydrogen energy systems. The dataset represents a local energy community in Porsgrunn, Norway, consisting of 400 electricity end users, including residential, commercial, and industrial consumers and prosumers. It includes hourly smart meter data for electricity consumption and generation over a nine-month period (January to September 2024). The dataset features distributed energy resources such as rooftop solar PV (installed by 300 users), a 1.3 MW wind power plant and battery energy storage systems for 250 users. Electricity market data, including hourly buy and sell prices for 2024, are also included. On the hydrogen side, the dataset incorporates transport demand from (a) a real hydrogen-powered ferry operating in a northern Norwegian island and (b) 15 synthetic hydrogen buses modelled using Norwegian specifications and realistic operational patterns. Green hydrogen production is modelled using two electrolyzers (1.2 MW and 2.5 MW) along with associated hydrogen storage. The dataset would enable researchers to explore sector coupling, local energy market design, flexibility strategies and cost optimization of community scale integrated energy system.
