Abstract:	This report attempts to answer the question of upper limits to the amount of PV that can be fed into a power system without causing problems to the power systems? What sets the limits? What are possibilities of stretching the limits? And finally, what are the financial aspects of high concentrations of PV in a power system? The main conclusion is that the impacts of PV penetration are rather modest. PV and distributed generation must be considered in the future network planning. Network planners should actually have considered PV and distributed generation long time ago. In the short term, the most feasible solution to stretch the limits to PV penetration is to review the procedures for adjusting the MV/LV transformer tap changer positions. The costs of such a solution are likely to be rather limited. In the longer term, it is expected that more flexible and accommodated consumption (demand side management) will remove the barriers of limits to PV penetration. Concerning the financial aspects of PV penetration, PV is likely to offer benefits that far exceed the inconveniences to the utilities. No fundamental novel requirements are needed for the network operators. On the contrary, PV offers benefits to the power system, e.g. peak power shaving in areas with significant use of airconditioning.
