See how we secure investment for this solar project resulting in a reduction of 70% energy consumption
The Client, a prominent interior company with two plants in Bahrain, has one newer plant and a combined total of 15,000 m2 of available roof space. This substantial space serves as an incentive for the client to implement a Solar PV Rooftop System. Currently, the client’s annual energy consumption for both plants is 6MWh, incurring a cost of approximately 180,000 Bahraini Dinar per year. The proposed Solar PV Plant aligns with current regulations, enabling the client to achieve cost savings, meet carbon reduction goals, and leverage favourable regulations such as wheeling and net-metering—unique to Bahrain among the GCC countries. These regulations allow the client to wheel surplus production from the new plant to be consumed in the old plant, offsetting the utility bill with excess energy. The client’s current consumption is detailed below:

As per our analysis, several issues are evident in this project. The first challenge arises from the plants being situated in two different locations, each linked to separate meters. While the initial analysis idealistically envisions covering the entire rooftop with solar panels, the reality of dealing with two separate locations introduces distinct challenges and meteorological constraints.
The second challenge stems from significant differences in energy consumption between the two facilities. The older facility, facing more issues and inefficiencies, exhibits higher energy consumption. Lastly, the expanding operations have led to an increase in energy demand, subsequently raising tariff rates, adding complexity to the project, as discussed earlier.

The primary objective of this project was to offer the client a comprehensive solution, not only involving the implementation of solar plants but also enabling the wheeling of excess energy generated from one plant to the other. Ark Energy’s analysis revealed a potential of 2.9 MWp for the Solar PV system, projecting to address 70% of the combined energy demand.

Ark Energy, in the role of the client’s consultant, effectively implemented the activity through a twelve (12)-step structured approach to ensure the best tariff rate with a Solar PV system that outlives the Solar Leasing Contract.
We successfully secured a third-party investor to fund the development of the solar PV system and optimize the efficiency of the generator sets under a leasing (PPA) agreement. In this 20-year contract, the client will be paying for the utilized solar power and generator power. The system produced 3,000 MWh per year, paid at a rate of 24 BD/MWh instead of 29.
Wheeling regulations allow the client to treat the two (2) plants as one asset, by transferring excess generation between the assets, and then offset the consumption of the old plant with Net Metering
