Technical due diligence and advisory services

Case studies Service: Electrical design and grid connection and due diligenceClient: Confidential

TNEI reviewed a portfolio of South American operational and in-construction wind projects totalling over 700MW in capacity. The review comprised an initial red flag review followed by a detailed assessment. The client used TNEI’s assessment to determine OPEX risks and refine their bid for acquisition of the portfolio. TNEI identified risks associated with grid curtailment which led to reduced generation export and revenue losses and also identified issues with the electrical site infrastructure design which presented potential risks to the safe and efficient operation and maintenance of the projects.

Service: Grid connection due diligenceClient: Confidential

TNEI assessed a portfolio of 16 UK wind projects varying in capacity from 20MW to 100MW, with a mixture of transmission and distribution connected schemes for a European utility. The assessment of the grid connection opportunities and risks for each project were used by the utility in their preparation of a bid for the portfolio of wind farm projects. For each project, TNEI provided a review and assessment of the connection documentation available and an assessment of the grid connection costs including use of system charges and embedded benefits. TNEI also provided advice on the timescale of the connection, network constraints and potential curtailment.

Service: Noise impact due diligenceClient: Confidential

To inform our client’s bid process, TNEI’s acoustics team carried out a review of a portfolio of wind energy sites across the UK. The sites were at varying stages of development ranging from initial feasibility through to having gained planning consent. All required some degree of noise modelling and analysis and review of third party assessment. Several sites were subject to complex cumulative noise issues. Our assessment was undertaken to tight timescales allowing our client to focus on the sites that matched its risk and investment criteria and to proceed through the bid process.

Service: Consenting and environmental due diligenceClient: Confidential

To support a legal action, TNEI undertook a review of the consenting process and of the assessment and application works undertaken by a third party on a portfolio of wind energy sites. Expert opinion on the appropriateness of the works and compliance with statutory requirements and best practice based on our extensive wind energy experience were provided.

Service: Electrical systems due diligenceClient: Confidential

TNEI completed a due diligence project to examine two German offshore HVDC interconnector projects, Dolwin1 and Sylwin1. Our role was to provide due diligence advice from the perspective of the electrical systems. This involved discussions with legal teams, financial teams and regulatory experts in order to explain the technology, analyse the technical risks and provide advice regarding the risk of unavailability and failure. Discussions with TenneT, one of the German System Operators, and regulatory advisors developed an understanding of the German electricity market and regulatory system.

Service: Technical due diligence (multi-discipline)Client: Confidential

TNEI was appointed to provide specialist input on grid, power systems, noise and consenting aspects for a portfolio of wind farms in Ireland, on behalf of an investor. The scope of works comprised an initial red flag review highlighting key portfolio risks, which was later followed by detailed assessment of each project. TNEI also provided input to the client’s financial advisor on operating costs and technical revenue factors to be considered in the valuation.
