The Electricity Authority of Cyprus (EAC), which is responsible for the transmission and distribution of electricity in Cyprus, publishes RES-E hosting capacity information as part of its efforts to facilitate the integration of RES into the national grid. This information is presented through the hosting capacity map, which is a key tool for understanding the potential for RES integration at the substation level.

RES-E hosting capacity is the maximum RES capacity that can be installed at the transmission substation level. It is presented in the hosting capacity map that has been created by both DSO and TSO of Cyprus (TSOC) as part of the Cyprus Transmission and Distribution System Redesign Study for 2021–2030, prepared as per the Cyprus Regulatory Authority Decision 02/2019. It aims to provide useful information to concerned parties on the RES-E integration capability of the Cyprus power system.

The hosting capacity map is essentially a tool that geographically illustrates RES-E hosting capacity per transmission substation. It also presents the RES-E available hosting capacity, i.e. the remaining available RES-E integration capability, which results by subtracting the already installed RES-E systems from the overall hosting capacity. It should be noted that systems that have already signed the preliminary connection terms are considered as installed.

Caution should be exercised, as all information presented in the hosting capacity map is indicative and non-binding for connection approval by the DSO or TSOC. Each connection request is assessed individually, and several other factors are taken into consideration. In particular, hosting capacity in this framework is evaluated based only on technical criteria; therefore, other factors, such as land availability, are not taken into consideration. Finally, it should be noted that RES-E connection at a substation with high available hosting capacity does not necessarily guarantee a faster connection implementation.

Both SOs make their active grids available to all current and potential electricity market participants, with full transparency and equal treatment in support of a successful energy transition.
