- New PPA product gives businesses a better alternative for their electricity
supply

Mainstream Renewable Power ("Mainstream"), the pureplay global wind and solar
company majority-owned by Aker Horizons ASA, has reached financial close on its
50 MW Ilikwa solar PV plant. The power from the plant will supply multiple
private commercial and industrial customers under flexible, shorter-term Power
Purchase Agreements (PPAs) in a new-to-market product called Renewable Energy
Supply Agreements ("RESAs").

This new product opens up the energy market in South Africa by giving a wider
range of businesses access to affordable, reliable and renewable power through
shorter-term energy contracts of between five and 10 years.

Commenting on the announcement, Mainstream's General Manager for Africa, Hein
Reyneke said: "We are excited to bring this new product to market, offering
customers the opportunity to secure flexible, clean and lower-cost electricity.
With a 12 GW portfolio, Mainstream has one of the largest and most advanced
pipelines of projects in the country.  Importantly, we have a further 180 MW of
projects ready for construction in 2025 and we encourage businesses to take
advantage of the benefits this new product offers."

Investec is a project partner, providing pre-construction development finance as
well as debt and equity finance for the construction of the plant. Mainstream
has a 70% equity stake in the project and Investec has a 30% equity stake.

Construction of the Ilikwa solar PV plant, located in the Free State province,
has already commenced, and is expected to reach commercial operation in early
2026. This is the second solar plant with private PPAs that Mainstream has taken
to financial close in South Africa within the last year.  When fully
operational, it will produce 141 Gigawatt hours (GWh) of electricity per year,
powering the equivalent of more than 42,000 homes and avoiding the annual
release of approximately 100,000 tons of CO2.

Ends.
