Sustainable Energy Action Plan (SEAP)

In many cases, national policies require municipalities to produce SEAP to access EU funds directed for increasing renewable’s participation and reduce air pollution.

Zefir system is capable to assist in creating SEAP by automatizing technical and economical calculations, requiring advanced analyses. It can produce objective results, accessible at the local and easily monitored from the central level.
