Concerning projects falling under the category set out in Annex II.1(e), each function listed in Article 4 shall be evaluated against the following criteria: Level of sustainability: This criterion shall be measured by assessing the reduction of greenhouse gas emissions, and the environmental impact of electricity grid infrastructure. Capacity of transmission and distribution grids to connect and bring electricity from and to users: This criterion shall be measured by estimating the installed capacity of distributed energy resources in distribution networks, the allowable maximum injection of electricity without congestion risks in transmission networks, and the energy not withdrawn from renewable sources due to congestion or security risks. Network connectivity and access to all categories of network users: This criterion shall be measured by assessing the methods adopted to calculate charges and tariffs, as well as their structure, for generators, consumers and those that do both, and the operational flexibility provided for dynamic balancing of electricity in the network. Security and quality of supply: This criterion shall be measured by assessing the ratio of reliably available generation capacity and peak demand, the share of electricity generated from renewable sources, the stability of the electricity system, the duration and frequency of interruptions per customer, including climate related disruptions, and the voltage quality performance. Efficiency and service quality in electricity supply and grid operation: This criterion shall be measured by assessing the level of losses in transmission and in distribution networks, the ratio between minimum and maximum electricity demand within a defined time period, the demand side participation in electricity markets and in energy efficiency measures, the percentage utilisation (i.e. average loading) of electricity network components, the availability of network components (related to planned and unplanned maintenance) and its impact on network performances, and the actual availability of network capacity with respect to its standard value. Contribution to cross-border electricity markets by load-flow control to alleviate loop-flows and increase interconnection capacities: This criterion shall be estimated by assessing the ratio between interconnection capacity of a Member State and its electricity demand, the exploitation of interconnection capacities, and the congestion rents across interconnections.
