MAINSTREAM RENEWABLE POWER LIMITED
MAINSTREAM RENEWABLE POWER LIMITED is a Private limited company (Ltd.) registered in Ireland under IE453076, and its current status with Companies Registration Office (CRO) is active. The company was incorporated on 8 February 2008 and lists its registered address as Leopardstown, Ireland. 1 shareholder is on record for MAINSTREAM RENEWABLE POWER LIMITED, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn.
