The nexus between growing shares of renewables (penetration), storage
requirements, and curtailment was studied using a linear optimisation
model. The study was performed using a dataset of Israel’s electricity
system. Five scenarios are designed to assess the techno-economic impact
of curtailment under various policy-based frameworks. The results show
that the three parameters are linked to each other in a way that
necessitates simultaneous increase of a total loss (curtailment plus
storage efficiency), penetration and storage capacity in the energy
transition. Depending on the curtailment policy, penetration increases
significantly with a small increase in storage capacity until it reaches
a corresponding point of inflection. Based on these physical
relationships, storage technologies were classified as diurnal and
seasonal. Diurnal storage capacity continually increases to a maximum
capacity of about daily average demand, which corresponds to a
penetration of approximately 90% of annual demand where the deployment
of seasonal storage significantly increases. Having no curtailment was
shown to lead to higher total system cost as compared to the system
optimised with curtailment. Overall, the nexus between the three factors
was shown to define when to deploy and dispatch storage technologies.
The evidence supporting these findings is detailed for the first time.
