Without intelligence, renewable energy is just a commodity.
The case for renewable energy is undeniable: it reduces costs and is good for business. Yet the challenge has shifted from simply purchasing the cheapest renewable energy to securing renewable energy value that remains robust across a range of future scenarios.
The trilemma
Renewable energy procurement is not as simple as it seems
Businesses face a trilemma when procuring renewable energy. Trade-offs are required between the savings achieved, the business's risk appetite and its targeted emissions reduction. To date, achieving an optimal outcome across all three has proved elusive for businesses in South Africa.
The risk
Renewable energy procurement exposes businesses to significant risks
Traditional renewable energy approaches have largely focused on securing supply at an attractive price, treating renewable energy as a commodity. However, this leaves businesses exposed to three substantial risks: variable renewable generation, unpredictable electricity consumption and uncertain future market prices. The consequences can be severe. Discovery Green's research found that the annual savings achieved by a business can vary by up to 35% in either direction for wind generation and by up to 19% for solar generation. In some scenarios, anticipated savings can turn into losses.

FREQUENTLY ASKED QUESTIONS
What is EnergyOS?
EnergyOS is Discovery Green's proprietary renewable energy operating system. Built on a shared data lake, it combines forecasting, customisation and allocation models to help businesses achieve higher savings, greater renewable-energy coverage and lower risk. EnergyAI runs throughout the system, continuously learning from real-world outcomes to strengthen decisions over time.
Who is EnergyOS for?
EnergyOS powers every Discovery Green solution. It is designed for businesses seeking to maximise the value of renewable energy while balancing savings, coverage and risk according to their unique requirements.
How does EnergyOS create value for businesses?
EnergyOS creates value by helping businesses maximise long-term financial value, reduce exposure to market volatility and increase renewable-energy coverage. By continuously forecasting, customising and optimising renewable-energy allocations, it helps deliver stronger outcomes across a wide range of future scenarios.
Why does more renewable energy coverage not always mean more savings?
More renewable-energy coverage does not always translate into greater savings. As coverage increases, the likelihood of a mismatch between renewable generation and business consumption also increases. This can lead to wasted energy and reduced economic value. EnergyOS helps identify the optimal balance between coverage, savings and risk, ensuring clients capture the greatest long-term value rather than simply maximising renewable-energy volume.
What causes volatility in renewable energy generation and consumption?
Renewable-energy outcomes are influenced by many variables, including changing weather conditions, fluctuating energy demand, evolving business requirements and future market prices. These variables create uncertainty, which EnergyOS is specifically designed to forecast, model and manage.
How does EnergyOS use actuarial principles?
EnergyOS applies Discovery's actuarial expertise, developed over more than 30 years in insurance and healthcare, to renewable energy markets. The same principles used to understand, price and manage uncertainty are applied to forecasting, customisation and allocation decisions. This helps businesses make more informed energy decisions and achieve more robust outcomes under changing market conditions.
How can businesses get started with EnergyOS?
EnergyOS powers Discovery Green's renewable-energy solutions. The process begins with understanding a business's consumption profile, coverage objectives and risk requirements. EnergyOS then uses this information to design a client-specific solution. Businesses can start through Green FLEX, Green SAVER or Green GUARANTEE, depending on their energy strategy and objectives.
How is EnergyOS different from traditional renewable-energy solutions?
Traditional renewable-energy solutions typically focus on supplying renewable electricity. EnergyOS goes further by continuously forecasting future conditions, customising solutions to each client's requirements and optimising energy allocation across Discovery Green's portfolio. This helps businesses achieve higher savings, greater renewable-energy coverage and lower risk, even as market conditions change.
