Private operators of solar plants basically function as their own power suppliers every day:
they consume power while the plant supplies it. This results in the on-site use of solar power and is, in itself, nothing new. What is new is that law-making authorities now want to promote the on-site use of solar power and are providing funding for it, making it an even more appealing option.
The on-site consumption of solar power is appealing as it has a considerable influence on the solar power plant’s return on investment. The more self-generated power the plant operator uses on site, the higher the effective payment per kilowatt hour.
For many years, payments for solar power were fully independent of on-site power consumption. Now, however, coordinating consumption and generation is becoming increasingly important. As a result of payment reductions, VAT payments and power procurement cost savings, the operator can expect to receive roughly six cents more per kilowatt hour of self-consumed solar power than would be the case for conventional feeding-in. On-site consumption is thus becoming a defining factor for the profitability of solar power plants.
