    Increasing shares of wind and solar generation serve to decarbonize electricity generation; however, their temporal and spatial variability poses challenges in grid operation. While grid expansion is restricted in the medium term, storage technologies can potentially increase the power systems’ efficiency by temporally aligning generation and demand and increasing network utilization. This paper uses a theoretical and a numerical model to evaluate the optimal allocation of battery storage. In a case study for Germany, we find that batteries can reduce system costs when placed behind the north-south grid bottleneck and near solar power. The supply costs in a setting with uniform prices and a random battery distribution are 9.3% higher than in the theoretical first-best benchmark with nodal prices. An optimal allocation of batteries can reduce this efficiency gap by 0.7 percentage points to 8.6%. This corresponds to almost a doubling of the supply cost savings per euro spent on battery installation. Due to a lack of spatially differentiated investment incentives under the German uniform pricing scheme, batteries have to be allocated by additional policies. Simple allocation rules such as tying battery siting to solar capacity or explicitly identifying a limited number of suitable sites and auctioning capacity can approximate an optimal allocation.

    Electricity grids as well as oil and gas supply chains are masterpieces of engineering, prime examples of second-to-second supply-demand matching, and the backbones that power modern economies. Yet, they also emit 72% of greenhouse gas emissions globally, cause geopolitical issues and leave billions of humans unserved. To address these issues, the industry is rapidly evolving: over USD9.5 trillion were invested in the power sector since 2010 and new technologies like EVs, energy storage, or green hydrogen challenge the status quo. Add to this the ever-changing policy landscape, the need for rapid decarbonization, and vocal, but heterogeneous customer interests and one reaches a business model landscape that is in rapid flux.In this dissertation, I study those evolving energy markets to help us understand how to best integrate new technologies and customer choices to ensure a future with greener power for more people on this planet.In the first chapter When Should the Off-grid Sun Shine at Night? Optimum Renewable Generation and Energy Storage Investments, I model how solar power and energy storage technologies can help off-grid locations, like islands or remote villages, to partially replace fossil fuel generation which can help reduce emissions, lower electricity costs, and increase access to electricity.In the second chapter Privately-Owned Battery Storage - Re-Shaping The Way We Do Electricity, I develop a structural model to explain why residential households invest in their own battery storage next to buying solar panels and how they utilize electricity. I estimate those preferences and utilities using a proprietary, big-data-set of German households and then study how private-owned battery storage impacts household behavior, grid-load and make policy recommendations.In the third chapter Quality-Adjusted Power. Where to Optimally Locate Wind Turbines, I develop a metric to quickly compare different locations for wind-power development that consider the natural resource quality, the distance to load centers, transmission constraints, and the timing between local wind-power generation and electricity demand in the market.
