Hybrid Power Plants (HPPs) combining wind, solar, and storage offer a promising solution to renewable variability. This thesis presents a techno-economic analysis using DTU’s HyDesign tool to quantify how demand–generation alignment, compared to baseload operation, influences reliability and costs. On the economic side, an indicative Power Purchase Agreement (PPA) valuation framework is introduced, tailored to demand-responsive HPPs and designed to capture operational risks and uncertainties. Results show that well-aligned demand profiles achieve high reliability at lower cost, while baseload operation drives overbuilding, curtailment, and higher PPA premiums. These findings position demand-responsive HPPs as a cost-effective alternative to baseload strategies.
