Green Energy

Investment in a renewable future

With its extensive portfolio of services, INP International Project has been involved in the “energy transition” for many years. In addition to supporting our customers in optimizing the energy efficiency of existing systems, we also assist them in the design, engineering, and implementation of new renewable energy systems. Moreover, we help them integrate renewable energy concepts in existing systems.

With expertise and professional competence in all areas of power generation and power transmission, INP International Projects has been offering its customers an extensive as well as specialized range of services in the field of green energy and decentralized energy for 35 years.  We have been collaborating with our customers for years on replacing fossil fuels and centralized power generation with renewable concepts without losing sight of the stability and necessary expansion of our power grids. With the ingenuity of our engineers, we make a significant contribution to a sustainable energy and supply infrastructure.


Services for Power Generation and in Energy Grids

  • Configuration and conceptual design of partial grids and micro isolated systems, e.g. combination of photovoltaics and battery storage, sector connection
  • Configuration and conceptual design of carbon-free site infrastructures
  • Concept development for the reuse or repurposing of existing conventional sites, e.g. for the supply of district heating 
  • Integration of renewable energy generation and utilization concepts, e.g. electrolysis, hydrogen storage, fuel cells, battery storage, combined heat and power units (CHPs), and photovoltaic systems
  • Adaptation of existing systems to external boundary conditions, e.g. system services (primary and secondary operating reserve), peak load capping, intraday load shifting
  • Stabilization of grids, e.g. by integrating battery or alternative storage systems
  • Increasing the information density and the automation level, e.g. for grids subject to redispatch requirements
  • Integration of central control room concepts, e.g. for merging of systems or for central data processing
  • Implementation of ideas into technical and profitable concepts 
  • Development of eligible concepts
