A Utility with an aging fleet of diesel generators is faced with aggressive national renewable energy targets. The client needed a cost-effective design, integration, and procurement of a renewable energy system that will meet the country’s target of 100% renewable energy by 2050.


HRE delivered a techno-economic study of feasible systems sizes with cost estimates. After driving consensus with the client, HRE delivered an engineering design and RFP package to support the client’s efforts to go to market.


Based on HRE’s recommendations, the client won Investment Committee approval to advance the project. HRE is now supporting the client’s procurement of an EPC partner to execute the work.
