The Client

The Electricity & Water Authority (EWA) in the Kingdom of Bahrain aims to provide electricity and water services at the highest level of quality and reliability to ensure sustainable development in the country and to be a best practice model for providing electricity and water services.  

To enable economic and social growth envisaged by Bahrain’s 2030 Economic Vision, EWA is committed to the delivery of ambitious and challenging transmission and distribution (T&D) development projects. 


The Project  

One major programme undertaken has been to strengthen the overall infrastructure and achieve expansion and reinforcement of existing 220kV and 66kV transmission & distribution networks in the Kingdom.  

As a utility-based consultant ESB International has developed, maintained and operated resilient transmission & distribution infrastructure in Ireland for nearly 100 years and internationally for close to five decades. ESB International was appointed by EWA as the consultant to deliver all four phases of this ambitious project. The overview of works completed for Phases 1 and 4 is as follows:
