Background Story
A water bottle manufacturing company in Lebanon currently relies on a diesel genset to meet all its power demands. The gensets operate to supply the company's annual consumption of 8 MWh, resulting in an annual cost of 2 million USD. The client has approached Ark Energy to reduce their dependence on diesel by implementing a hybrid solar-diesel power plant. Given the available space and existing limitations, the client has the capacity to install a 1.4 to 1.5 MWp solar PV system on their facility’s rooftop.

Problems
Several challenges arose during the project. The client heavily relied on gensets due to the country's instability and frequent utility outages, with blackouts lasting between 5 and 8 hours per day. Additionally, the gensets operated inefficiently, whereas newer technologies could deliver similar energy output with significantly lower diesel consumption.

Beyond technical challenges, financial constraints also emerged. The client sought a third-party investor to contribute to the project's development, with strict criteria set for investor selection. This was crucial, as the client, despite supporting the initiative, was unable to finance the project independently.

Main Objective
In terms of hierarchical importance, the primary objective was to secure the most suitable investor—one that aligns with the client’s criteria—and implement the Solar PV plant to reduce reliance on the diesel genset. Analysis indicates that the optimal solution lies in utilizing a Solar PV system, which is expected to deliver the following benefits:

Approach
As Ark Energy, the client’s consultant, we strategically navigate challenges and execute a structured twelve-step approach. This ensures the optimal tariff rate and the implementation of a Solar PV system designed to outlast the typical lifespan of a solar leasing contract. We successfully secured a third-party investor to fund the development of the Solar PV system while also enhancing the efficiency of the generator sets through a leasing (PPA) agreement. Under this agreement, the client pays for both solar and generator power consumed throughout the contract term.
