Decentral Energy production and integration in the Stavanger region - A techno-economic case study of Stavangerregionen Havns and Risavikas solar production potential and its contribution to the local energy challenges within the Elnett21 project

Abstract

This thesis explores the solar production potential of Stavangerregionen Havn and Risavika and its possible contribution to the local energy challenges within the Elnett21 projects, that arises with the transport electrification strategy from the Norwegian government. The aim of this study is first to show the solar electricity generation potential for the given buildings and then investigate an economic long-term performance of those projects. Furthermore, will be explored how the integration of local produced electricity can be supported by battery storage systems.

The thesis uses a Mixed-Method approach which gives the option to explore qualitatively the possibilists and challenges of the concept of system decentralization, decentral solar production and battery storage. Additionally, is through the utilisation of the K2 and PVsyst software the simulated electricity generation potential explored on which bases the quantitative analysis and economic evaluation is executed.

Our analysis shows that Stavangerregionen Havn and Risavika have great electricity production potential which could be utilised. Furthermore, gives the economic long-term evaluation a positive output for the Ferry-Terminal as main case study object. We concluded that through the development of local generated solar electricity and the utilisation of battery storage significant contribution towards Elnett21 and the challenges are possible. Dependent on the size of future solar production and battery storage capacity can the contribution be bigger or smaller.
