Managing uncertainty for DSOS

With 80% of new renewable energy sources expected to connect at the DSO level, long-term grid planning faces significant uncertainty. Complex permitting and regulatory barriers slow grid expansion, while debates over integrating large-scale renewable projects, such as ffshore networks, further complicate future scenarios. To manage this uncertainty over a 10+ year horizon, DSOs must broaden the toolbox of available technologies for network development. Many Innovative Grid Technologies (IGTs) are commercially available but remain underutilized due to lengthy type-testing and a lack of standardization. Collaborative testing frameworks and reliance on peer-reviewed evaluations could accelerate their adoption. IGTs can also serve as flexible, cost-effective solutions to fill gaps where traditional grid expansion is delayed, reducing the need for extensive future build-outs. Additionally, leveraging consumer-side flexibility can complement these efforts. This paper introduces a cost-benefit analysis framework tailored to the evolving needs of DSOs, emphasizing the value of IGTs in managing uncertainty. The analysis highlights how faster deployment of innovative solutions can address short-term challenges while ensuring long-term grid resilience. The paper concludes with actionable recommendations for industry stakeholders, regulators, and the European Commission on integrating IGTs into DSO planning to enhance flexibility, efficiency, and reliability.
