Enhancing Sustainability in Hopedale, Newfoundland and Labrador, Through Hybrid Microgrid System Design
Journal Title: Power Engineering and Engineering Thermophysics - Year 2024, Vol 3, Issue 1
Abstract
An evaluation of renewable energy system (RES) adoption in Hopedale, Newfoundland and Labrador, was conducted with the focus on developing a robust hybrid microgrid system. Situated in a remote area distinguished by its severe weather and rich cultural history, Hopedale primarily relies on diesel generators for energy, presenting unique challenges including high energy costs and significant environmental impacts. The current reliance on three diesel generators for electrical needs underscores the necessity for a shift towards sustainable energy. Hybrid Optimization of Multiple Energy Resources (HOMER) Pro simulations were employed in this study to analyze a proposed system integrating solar and wind power, battery storage, and an additional diesel generator. The system's design aims to reduce dependency on fossil fuels amidst increasing environmental concerns and fossil fuel limitations. The environmental performance and cost-effectiveness of combining solar and wind energy with battery storage and a diesel backup were assessed. The hybrid system's potential to decrease carbon emissions by over 50% compared to the existing diesel-only setup is demonstrated, suggesting a substantial reduction in greenhouse gas emissions. Although the economic Levelized Cost of Energy (LCOE) of $0.182 per kWh is higher than the traditional diesel cost of $0.16 per kWh, it represents a strategic commitment to environmental sustainability. A Net Present Cost (NPC) of $14.6 million was predicted for the system, encompassing Capital Expenditure (CAPEX), Operational Expenditure (OPEX), and replacement cost over 25 years. Significant reductions in environmental impact and notable operational savings were anticipated. These findings contribute valuable insights into the benefits of hybrid microgrids for remote communities, offering a model for energy resilience, cost savings, and reduced carbon footprints. Thus, the study adds significant information to the ongoing discourse on sustainable energy solutions for isolated locations.
