Large energy transfer projects, whether at the national or international level, hold significant importance due to their environmental impacts. In this context, attention to routes known as energy corridors, which can provide a platform for the transfer of multiple energy sources with minimal environmental effects, can play a crucial role in reducing environmental impacts. This study focuses on designing an east-west energy transfer corridor in Iran using Least Cost Path Analysis to achieve a multifunctional energy transfer corridor. The research employs GIS technology and Least Cost Path Analysis to identify the most efficient and cost-effective routes for energy transfer, considering geographical and environmental factors. The results indicate that the proposed routes significantly reduce costs while minimizing environmental impacts. These effects, by decreasing the need for land acquisition, contribute to a reduction of up to 30% in acquisition costs and up to 15% in total project costs, thereby enhancing the overall efficiency of energy distribution. The use of Least Cost Path Analysis in designing energy transfer corridors can lead to more sustainable energy solutions in Iran, effectively addressing both economic and environmental concerns.

Introduction
Optimizing pipeline routes is a crucial component in the development of energy infrastructures, especially in light of the increasing global energy demand and environmental considerations. As countries strive to balance economic growth with ecological sustainability, the need for efficient and effective methods for determining pipeline routes has become more. Energy corridors are vital infrastructures that facilitate the efficient and sustainable transport of energy resources, including oil, natural gas, and electricity, from production sites to consumption centers. Strategic planning and optimization of these corridors are essential to ensure energy security, minimize environmental impacts, and reduce economic costs. With the rising global demand for energy and the transition towards renewable energy sources, the importance of optimal routing of pipelines has become more pronounced.
Methodology
This study employs the Least Cost Path Analysis (LCPA) method, which utilizes Geographic Information Systems (GIS) to identify optimal routes. The research process includes several key stages: data collection, cost surface generation, path analysis, and validation of results. In the initial stage, relevant spatial data, including topography, land use, environmental constraints, and socio-economic factors, are collected. Then, a cost surface is generated that reflects the costs associated with traversing different land uses. This surface is created by assigning weights to various factors based on their impact on construction and operational costs. In the next stage, algorithms such as Dijkstra or A* are used to determine the least-cost path. Finally, validation and sensitivity analysis are conducted to assess the robustness of the identified paths against changes in data and input assumptions.
Results and Discussion
The results indicate that the optimal routes identified using LCPA significantly reduce construction costs and minimize environmental impacts. This analysis also addresses the challenges faced in pipeline design, including geographical constraints and environmental concerns. For instance, poorly designed routes can lead to increased construction costs, environmental degradation, and conflicts with local communities.Therefore, adopting advanced optimization techniques like LCPA is crucial for ensuring the efficient and sustainable routing of vital pipelines.
Numerous challenges confront planners in designing pipelines. These challenges include traversing diverse terrains, avoiding ecologically sensitive areas, and complying with legal and political restrictions. Key challenges can be considered as foundational elements in any design. For example, pipeline routes must cross various landscapes, including mountains, rivers, and urban areas, which can significantly impact feasibility and
Conclusion
This research demonstrates that the application of LCPA in the design of energy corridors can lead to more sustainable energy solutions and effectively address economic and environmental concerns. Given the existing challenges in pipeline design, there is an urgent need for systematic, data-driven approaches to optimize pipeline routing. Additionally, the need to consider security protocols, especially in political and security contexts, can complicate the routing of pipelines and increase costs.
Ultimately, this study examines methods, case studies, results, and implications of using LCPA to determine energy corridors. By analyzing the integration of various factors and specific project outcomes, this discussion aims to highlight the effectiveness of LCPA in promoting the development of sustainable energy infrastructures. Adopting a multifaceted approach to corridor routing that prioritizes not only economic considerations but also environmental sustainability and social acceptance is emphasized.
The MCDA-LCP analysis is highly effective in geographic data analysis as it can store geographic data and analyze them more efficiently and conveniently than paper. All spatial criteria are combined and analyzed to produce a cost surface for the entire study area. LCP rapidly and continuously examines a set of data across a wide area to determine the least-cost path. Based on the two cost levels in this study, the least-cost routing tool performs better than existing ROWs.
Given the importance of integrating various functions within a corridor, this study explores how to enhance the resilience of energy systems and reduce vulnerabilities to disruptions. Moreover, by limiting the spatial impacts of energy and transportation networks, it helps reduce land degradation and habitat fragmentation.
Pipeline design is accompanied by multiple challenges. On one hand, planners must address the lowest economic costs, while on the other hand, they must consider the lowest environmental and ecological costs. These challenges include traversing diverse terrains, avoiding ecologically sensitive areas, and complying with legal and political restrictions. For instance, steep slopes, unstable soils, and earthquake-prone areas create additional hazards that must be mitigated through careful path selection.
Additionally, environmental and ecological concerns are primary considerations in the planned designs. Energy corridors often traverse protected areas, wildlife habitats, and water bodies, raising concerns about biodiversity loss and ecosystem disruption. Environmental impact assessments (EIA) are mandatory in most jurisdictions, requiring pipeline planners to minimize ecological harm.
In conclusion, this research clearly demonstrates that the use of LCPA in the design of energy corridors can lead to more sustainable energy solutions and effectively address economic and environmental concerns. Given the challenges in pipeline design, there is an urgent need for systematic, data-driven approaches to optimize pipeline routing. This approach can contribute to cost reduction and improved efficiency in energy projects, ultimately aiding in the achievement of sustainable development goals in this sector.
