Pathways to Low Emission Energy Systems in the Baja California Peninsula - A Study of Implementation of Renewable Energy in Isolated Systems

Sammanfattning

As the global energy sector undergoes a necessary transition toward renewable sources, Mexico has committed to significantly expanding its clean energy capacity. The Baja California Peninsula, with its rich solar and wind resources, presents a unique opportunity to lead this shift. The peninsula is composed of two states: Baja California and Baja California Sur. Baja California operates one electrical system, while Baja California Sur has two distinct systems. These regions are isolated from the national grid, with the exception of Baja California’s northern part, which is connected to the United States at two points in the north. However, the geographical isolation of the region from the national grid introduces both technical and economic challenges that must be addressed to enable a more efficient and integrated energy system. This study explores potential energy transition pathways for the Baja California peninsula by modeling various scenarios. The analysis evaluates the feasibility and impact of integrating renewable energy sources, particularly solar and wind power, alongside energy storage solutions to ensure grid stability and meet future energy demands. The results highlight that solar power, combined with energy storage, overall offers the most cost-effective pathway to meet the peninsula's growing energy demand, reducing reliance on fossil fuels. However, the findings also reveal key challenges that must be addressed to achieve a successful transition, including infrastructure bottlenecks, high initial capital costs, and the need for extensive policy support. Expanding and modernizing the transmisson network is a critical factor in enabling renewable energy integration, as the most resource-rich regions for renewable energy are often located far from the existing grid. The potential for overproducing electricity for storage and export appears promising in terms of reducing emissions and ensuring long-term cost-effectiveness. However, its feasibility is heavily reliant on the creation of favorable policy environments, which include clear incentives for renewable energy development and a stable regulatory framework for energy trade. This study highlights the critical need for strong policy leadership and substantial investments in both infrastructure and technology to enable a successful transition to a sustainable energy system. In conclusion, while technical solutions for decarbonizing electricity production in the BC peninsula exist, achieving net-zero emissions will require coordinated efforts across multiple sectors. The success of this transition depends not only on technological advancements but also on political will, societal engagement, and international cooperation. Future research should explore the effectiveness of policy incentives, regulatory frameworks, and market mechanisms in accelerating renewable energy adoption, as well as the potential for cross-border energy trade or connecting the systems with each other or the national grid.
