Using solar PV to achieve decarbonisation goals without upfront capital
Mediclinic implemented solar PV across 29 hospital sites, using a PPA model for 10 sites, including Durbanville Hospital, to avoid upfront costs. The Durbanville installation, commissioned in November 2021, consists of a 704.6 kW (DC) system that produces approximately 1.17 GWh of green electricity annually, offsetting about 1,076 tons of carbon emissions. The 25-year take-or-pay PPA provided immediate savings, with initial electricity prices approximately 60% lower than municipal rates. The document highlights the benefits of PPAs for operational de-risking and financial hedging against rising grid costs, while recommending clear maintenance responsibilities and sector-specific provider experience for similar projects.
