Hydropower Engineering

The expansion of hydropower as a reliable, sustainable and long-term cost efficient source of energy is experiencing a renaissance in many regions. ILF actively helps shape this expansion by managing customized projects of any type and size. In the last 35 years ILF has successfully planned and designed 130 hydropower projects with capacities of up to 1,400 MW around the world. As a one-stop shop ILF provides integrated, interdisciplinary services for hydropower projects from the initial study, through the design and tender phase to commissioning and start-up. Emphasis is always placed on developing individual solutions that meet the most stringent quality standards and take complex framework conditions into account.

To optimize projects in terms of economic efficiency, ILF also uses unique special software (such as RENRisk) and performs financial analyses. The early integration of all relevant stakeholders to increase a project’s acceptance and likelihood of approval, and the diligent preparation of Environmental and Social Impact Assessments in line with international standards (e.g. IFC, equator principles) complement ILF’s range of services. Among ILF’s clients are public institutions, private project developers, renowned construction companies, and international financial institutions.
