The listed individual obligated parties must prove annual final energy savings according to individual targets defined based on their operating volumes and published by the Sustainable Energy Development Agency. However, there are different methodologies for evidencing the savings, and the initial expectations for increased investments have not been met as obligated parties found other options to report on their targets. However, if the scheme is improved and the control is strengthened, obligated parties may be motivated to invest in the residential sector. This is proven by the establishment of strong and active ESCO subsidiaries by most energy distribution companies, as their experience working with residential clients could be utilised.
