Diesel Generator Systems with Electrical Works -Lebanon”

1. BACKGROUND AND CONTEXT

Oxfam is a global movement of people, working together to end the injustice of poverty. Oxfam has been working in Lebanon since 1993. We provide humanitarian assistance to vulnerable people affected by conflict, and we promote economic justice and good governance, and women’s rights. Oxfam also works with local partners to contribute to the protection and empowerment of marginalized women and men.

Oxfam is seeking to establish a framework agreement with a qualified supplier for the provision of diesel generators.

This agreement will support the efficient and timely procurement of selected generator models, ensuring reliable energy solutions for humanitarian and development activities in the region.
