the result of the assumptions from the NPE, but also the requirement that the electricity system is CO2-free by 2035. Due to the high amount of solar, wind and nuclear capacity being installed, generation sources. In all variants, the current market fails to monetize the value of firm generation and flexibility capacities, with the exception of demand side response. An analysis capacity of about 2.2 GW in 2035, for which for instance batteries are currently already being free optimization, a significantly different energy system is observed. In this scenario, no additional offshore wind capacity beyond existing plans (21 GW) is observed, and no new nuclear energy is realized, ieading to almost double the onshore wind but reduced solar PV capacity. Because considerably less electricity is produced, the domestic green hydrogen production is cut drastically from 23 TWh to 7 TWh, relying more on electricity and hydrogen imports from neighbouring countries. Additionally, the reduced domestic renewable generation also decreases the demand for long-term storage and hydrogen infrastructure. This scenario reliance, but at the cost of decreased national self-sufficiency and adequacy. The overbuilding of renewables as planned in the Dutch National Energy System Plan by 2035, when optimally managed with storage, curtailment strategies and flexible demand, can
