Software solutions for every clean energy challenge

We power the trusted modeling and investment frameworks of top IPPs & energy developers

Clean energy is a risk driven market

Volatility, shifting PPA structures, and uncertain price projections make projects harder to finance. Developers carry risks, and without credible structures, they lose offtakers, see valuations fall, and face delays in securing financing.

We turn risk into value

Southern Lights builds software that helps developers, operators, and investors quantify risk and optimize projects across the full revenue stack.

From PPA price definition and contract levels to RES, BESS and hydrogen sizing and dispatch, our solutions transform complexity into clarity so you can make profitable, bankable decisions.

Confident decisions at every stage

From early concepts to investment approval. With Southern Lights you get the insights you need to take your project to the next level.
