Pilot site Luče

Pilot site Luče

COMPILE pilot site Luče represents a case of a rural low voltage network with a weak and unstable connection to the medium voltage grid. Luče has also a relatively weak local power grid which often encounters power failures and limits the integration of renewable energy sources (RES), as the voltage during the day rises above the limits. Outages are most common during times of extreme weather events like storms and thunderstorms. The initiator of the Luče Energy Community (EnC) is a local frontrunner who already installed PV, wind, EV charging point at home and who engaged the neighbours and municipality of Luče to establish EnC.

Where

Luče, Upper Savinja Valley, Slovenia

 

Goal

The goal is to establish a cooperatively enhanced EnC to increase the self-sufficiency and security of supply of the local energy system containing residential and commercial buildings with high penetration of RES. By becoming a part of COMPILE the Luče EnC aims to improve network conditions resulting in many socio-economic benefits for the community such as the operation of local agricultural business. Luče EnC aims to keep the interest of citizens in energy and climate topics, establish trust in local energy community and local RES production while becoming the first EnC in Slovenia.

Benefits

With a comprehensive approach, the project should provide benefits for all participants in the EnC. The entire system will represent the first such energy community in Slovenia which will be able to cover the electricity needs only from RES. The demo site will have a high grade of RES production units and a very diverse mix of energy systems. Trough COMPILE it will be possible to test and analyse different scenarios like inclusion of very high grade of RES production on a microgrid level and also to prove that reliability of supply issues on microgrid level can be successfully addressed with energy management of Local Energy Communities.
