Decentralised solar electricity generation on a large scale is a relatively new phenomenon. In the State of New York, the adoption of this form of renewable electricity generation has seen a surge over the last decade. However, policies that have been implemented over the last year, prompted experts to question the future of the market. The question is, what are the effects on energy security when these policies are in place? Using 3 relevant theories (TPB, VBN, and DOI) on household decision-making processes, a study of what is meant by decentralised solar and the context in which the market operates in the Empire State, I used an agent-based model to analyse the impacts of these policies in terms of energy security. Energy security is defined into 6 dimensions (Availability, Affordability, Accessibility, Acceptability, Ability, and Appeal). Experimentation and subsequent analysis showed a limited effect on most of these terms. However, a combination of these policies showed a less favourable effect on all scenarios as compared to the business-as-usual scenario. What was salient during experimentation was that the combination of the policies led to a difference in direction of the effects than when the effects of the policies implemented in isolation were added together. Indicating an inter-relationship between policies. Moreover, during market analysis it was found that the influence of the traditional utilities (owned by private investors) exert great influence on the policy making process, in their own favour. Based on this research, the future of decentralised solar electricity generation in the State of New York is going to be a tough battle with the greatest hurdle being overcoming the power of centralised utilities.
