“…Under the assumptions in this study, the system cannot continue to increase the PV penetration past approximately 30% PV penetration without the ability to utilize storage; we caution that this exact threshold might be system-specific, and future work is needed to confirm a generalizable value across systems with different sizes, configurations, and inter-regional exchanges. The ability of storage to reduce curtailment at increasing PV penetration is consistent with other literature 2,4,24,[35][36][37] and is one reason storage is deployed as PV penetration increases. We highlight this important role of storage, which is not explored further in this study apart from the static penetration levels embedded in our six system build-outs.…”

“…Similar to [35] and [6], it is found that the more flexibility there is in the system, the less need for electric batteries. As suggested in [57], capacity deferral is where electric batteries have the highest value, but further costs reductions are needed to exploit this value. Introducing ramping constraints and increasing time resolution could have increased the value of electric batteries.…”

<div>This paper analyses the role of sector coupling towards 2050 in the energy system of North Europe when pursuing the green transition. Impacts of restricted onshore wind potential and transmission expansion are considered. Optimisation of the capacity development and operation of the energy system towards 2050 is performed with the energy system model Balmorel. Generation, storage, transmission expansion, district heating, carbon capture and storage, and synthetic gas units compete with each other. The results show how sector coupling leads to a change of paradigm: The electricity system moves from a system where generation adapts to inflexible demand, to a system where flexible demand adapts to variable generation. Sector coupling increases electricity demand, variable renewable energy, heat storage, and electricity and district heating transmission expansion towards 2050. Allowing investments in onshore wind and electricity transmission reduces emissions and costs considerably (especially with high sector coupling) with savings of 78.7 EUR2016/person/year. Investments in electricity-to-heat units are key to reduce costs and emissions in the heat sector. The scenarios with the highest sector coupling achieve the highest emission reduction by 2045: 76% greenhouse gases reduction with respect to 1990 levels, which highlights the value of sector coupling to achieve the green transition.</div><div><br></div><div><br></div>

“…Many grid services that storage provides, including peak shaving, energy time-shifting, and operating reserve provisions, have declining value with storage penetration (Brijs et al, 2019;Denholm et al, 2020). Furthermore, these values are highly dependent on the grid system conditions and can change over time depending on the overall evolution of load, load flexibility, and the mix of generation technologies in the power sector (Hartner and Permoser, 2018;Mallapragada et al, 2020).…”
