Kigali Genocide Memorial in Gisozi

Centennial Solar Rwanda Battery Africa Genocide Memorial.png

Centennial's solar project at the Kigali Genocide Memorial in Gisozi was installed at no upfront cost to the Memorial.  The project meets the majority of the Memorial Center's power needs during sunlight hours and helps the facility to reduce its electricity costs and carbon footprint.  

During Phase 2 of the project, scheduled for later this year, Centennial will co-locate the existing solar system with battery storage in order to maintain the facility’s operational resiliency and reduce a large portion of the Memorial’s need for standby diesel generation.  

Hotel and Restaurant in Kiyovu

Centennial's battery storage system at a hotel and restaurant provides uninterrupted power supply to the facility and substantially reduces the need for emergency diesel fuel.

The system saves the customer money on fuel costs, and will be integrated with a solar system after a new addition to the hotel is completed in 2017.

The hotel and restaurant is located in Kiyovu, a neighborhood in Kigali, Rwanda.

CNBC Africa Interview with Centennial's Managing Director

CNBC Africa: At no upfront cost, Centennial offers affordable, reliable and non-polluting power systems for customers.  Our power systems integrate solar photovoltaic technology with battery storage systems.  Instead of selling the equipment to our customers, we sell the power that is generated from the equipment.  


Accelerator: Noting that the majority of solar investment in markets throughout the African continent is currently based in rural areas for pay-as-you-go solar kits in villages and large utility scale projects that sell electricity into the national grid, Founder and Managing Director of Centennial, David John Frenkil, said, “While these rural solar projects are extremely important for the region’s development, Centennial focuses on a currently under-addressed challenge for commercial and industrial customers in and near urban centers that need a more affordable and reliable power supply.”

Centennial installs solar power at the Kigali Genocide Memorial Center

The East African: "Instead of requiring upfront capital, Centennial is selling us the electricity generated by the solar system at a discount compared with our current power costs. This will allow us to dedicate more funds to our remembrance and peace education programs."

Centennial Generating Co. opens 1st phase of solar energy project in Rwanda

SNL Financial: The company said it is working with customers representing various sectors of Rwanda's economy, including hotels, office buildings, factories, mines, food distribution companies, health clinics and large residences. 

Solar Market Fundamentals Pointing to Increased U.S. Investment in Growth Markets

Power Finance & Risk: "The U.S. solar market is long on capital and short on deals. The competitive environment is driving down expected investor returns in the contiguous 48 states.  This is coupled with the ability of certain solar investors to tap relatively low-cost financing from the capital markets, especially at a time when U.S. solar incentives are, at best, awkward, arcane and perverse... [In growth markets,] investors can currently achieve unlevered returns in the mid-teens or higher."

Centennial Generating Co. Sees Fast-Growing Rwanda as Prime for Commercial Solar

SNL Financial: "We were attracted to Rwanda's good governance, rule of law and ... we were looking for a market where we can establish a long-term presence, bring local workers onto our team and add value in terms of offering reliable and affordable access to electricity in a way that reduces emissions."
