Competition for renewable energy projects is increasing. This has resulted in a shift toward large portfolio acquisitions, which have several benefits over single projects. Reduced technology risk and more predictable income streams are two of these benefits, which are typically quantified as the portfolio benefit. Reduced technology risk means that technology issues can be mitigated by using a mix of technologies, while having geographic diversity, regional weather effects can be balanced by higher revenues, so there is a more consistent generation profile. We look at how the portfolio benefit is evaluated and provide guidance on the typical magnitude of benefit that can be expected for different types of onshore wind and solar project portfolios.
