PPA(opex) Project with Banglalink

Engreen successfully completed several Solar-DG hybrid power solutions for one of the Leading Opereators of Bangladesh "BanglaLink".

In 2012 Engreen became the strategic partner of GREEN BTS Project of BanglaLink for total forty (40) sites with the vast scope including solar feasibility survey, solution, design, Equipment purchase & rollout, installation, testing and commissioning.

This project is under OPEX (PPA) model with a longer term (10 years) where Engreen is responsible for all power issues including operation & maintenance with the KPI target of 100% power availability.

The project is ongoing and currently the total completed Solar-DG Hybrid sites stands at 30 (Thirty) in no. spanning across all regions of Bangladesh.
