PROBLEMS
• No detail rules and lack of secondary legislation about TSO and DSO interrelations;
• DSO don’t want to invest (forward investments to the TSO);
• Payment for connection to the grid based on the estimates of the technical design project (risk of loss or win);
• Private DSO. Different view, different values, different point of view to the customers;
• Not legally constructed generators (no requirements from TSO, don’t want to pay for reserve).
