So, I usually write about P3 examples in the context of private sector assisting in meeting public sector goals, while still meeting their own financial return targets. Abu Dhabi is using the model for a very different context.
The nature of society in Abu Dhabi is (oversimplified here for brevity) that the 'public sector' pretty much dominates everything. Abu Dhabi is actually using the P3 model to help build and strengthen its own private sector capabilities.
This different perspective still arrives at the same conclusion of the overall value of the model - it enables all parties to achieve more than they could possibly do alone.
“Today’s announcement of AED10 billion of infrastructure projects marks a milestone in our commitment to partner with the private sector to drive Abu Dhabi’s economic transformation. The Abu Dhabi government is committed to further reinforcing the important role of the private sector in the economy, which is key for a sustainable, resilient future.”
