In a significant stride towards sustainable energy in Bulgaria over the past few years, Inea Consulting Ltd. is proud to announce the successful completion of technical due diligence (TDD) for a 112 MW wind farm project on behalf of an international investor. Upon the planned acquisition of the wind farm from a local developer, the project sponsor required support from an experienced consultant, such as Inea Consulting Ltd., and appointed the firm as a technical advisor to conduct third-party, independent Technical Due Diligence (TDD). 

The 112 MW wind farm project, located in Bulgaria, is planned to become a major contributor to the country's wind energy sector. It involves the installation of state-of-the-art wind turbines (with a capacity between 5 MW and 7.2 MW each), capable of harnessing the excellent wind resources in the area where it is situated to generate clean, sustainable energy. The project's development comes at a time when Bulgaria needs to increase its wind energy contribution to the power mix to support grid balancing, which is threatened by the rapid growth of solar energy in Bulgaria since 2021. The technical due diligence process was comprehensive and meticulous, ensuring that every aspect of the project was thoroughly evaluated.

Inea Consulting’s team of experts conducted an in-depth analysis of the project's technical feasibility, environmental impact, and financial viability, including:

• Site Assessment: The first step involved a detailed site assessment to evaluate the wind resources, topography, and accessibility. The site assessment covered the expected grid connection point, the proposed cable route, and the proposed MV/HV substation site, including photographs of the visible infrastructure (e.g., the MV/HV substation, nearby OHL steel towers, etc.). The adequacy of the wind power plant design and proposed technology in relation to site conditions was explored in detail. Inea Consulting’s team inspected the access to the site and the conditions of the existing road(s) to allow movement of trucks and other machines for the delivery of the wind turbine equipment and O&M of the proposed wind power plant.
• Environmental Impact Analysis: Inea Consulting’s team conducted a thorough environmental impact analysis to ensure that the project adheres to all environmental regulations and standards. This included assessing the potential impact on local birds and habitats, as well as developing mitigation strategies to address these concerns.
• Technical Feasibility Study: A comprehensive technical feasibility study was carried out to evaluate the suitability of the proposed wind turbines, the design of the wind farm layout, and the integration with the local grid infrastructure. Inea Consulting’s team provided comments on the technical aspects of the granted permits and authorisations required for the operation of the wind farm project. This study also included an assessment of the project's operational and maintenance requirements.
• Financial Viability: The financial viability of the project was assessed through detailed cost-benefit analyses, including capital expenditure, operational costs, and revenue projections. This ensured that the project is not only technically feasible but also economically sound.

The successful completion of technical due diligence (TDD) for the 112 MW wind farm project in Bulgaria marks a significant achievement for Inea Consulting Ltd. It underscores the company's expertise in renewable energy projects and commitment to sustainable development. As the investor is expected to move forward with the project, it will make a substantial contribution to Bulgaria's renewable energy sector, particularly the wind sector, and set a benchmark for future wind farm projects. Inea Consulting Ltd. extends its gratitude to all stakeholders involved in this process, including our dedicated team of experts, local authorities, and community members. Their support and collaboration have been instrumental in reaching this milestone.
