METIS 2 technical note T2 : energy system integration module.

This Technical Note introduces the newly developed METIS features that extend the tool capabilities to represent multi-energy systems and facilitate the assessment of energy system integration strategies, namely, a joint-optimisation of the power, hydrogen and industrial heat systems. This allows for an enhanced quantification of synergies resulting from sector coupling. Such flexibility alleviates the constraints on the system. This brings down operation cost by reducing the need for peak-load technologies and may allow for a more limited dimensioning of infrastructure, thus lowering investment needs to meet the energy demand.
