ENTSOG and ENTSO-E publish Artelys study on gas-electricity interlinkages

3 December 2019

ENTSOG and ENTSO-E publish Artelys study on interlinkages between gas and electricity systems. In this study, Artelys presents recommendations related to the identification of infrastructure projects for which the interactions between gas and electricity may significantly impact their assessment.

The objective of the study Artelys has carried out was to provide recommendations to the ENTSOs on the way to account for interlinkages between gas and electricity during the project assessment phase. The study has focused on the identification of relevant projects for which a joint gas-electricity assessment is recommended. The proposed screening methodology aims at identifying the relevant projects for which the interactions between the gas and electricity systems have a sizable impact on their economic assessment. After a thorough analysis of the interlinkages between the gas and electricity sectors, and a discussion of the role of the scenario building phase, three key sources of interlinkages have been identified and studied: gas-to-power, power-to-gas and hybrid consumption technologies (e.g. hybrid heat pumps). The screening methodology includes criteria related to each of these interlinkages.

—The power grid faces challenges in managing the increasing amounts of new wind and solar power generation. Grid Enhancing Technologies (GETs) are essential for optimizing the use of the existing infrastructure. Artelys carried out a study for Latvian Transmission System Operator (TSO) AST to assess the renewable generation hosting capacity of the transmission grid and to evaluate the benefits that GETs can provide to renewable integration. The study performed simulations using the open-source optimal flow tool, PowSyBI Metrix. Results show that Grid Enhancing Technologies can increase Renewable Energy Sources (RES) hosting capacity by up to 40% and were announced in the following press release.
