Dedicated renewable energy consultants, from concept to operations
OWC has worked with clients on wind power projects since 2011, but as a multi-disciplinary renewable energy consultancy, we’re equipped to deliver results across a wide range of sectors. If there is an emerging renewable energy market, we’ll be there to help you develop a strategy and achieve consistent results.
Discover our experience across the sectors
We work with you at every stage of a windfarm project’s lifecycle. With 330+ successful projects, we’ll support you every step of the way.
Solar-powered renewables are the fastest-growing renewable technology. With over 20 experts around the world, we can help you to succeed in this high-demand sector.
Our veteran renewable energy consultants can work on individual battery energy storage systems (BESS), or joint-market projects requiring specialist technical insight.
Through our sister company INNOSEA, OWC will work with you on technical, advisory, engineering and marine assurance services to support the development of ocean energy technologies.
Floating photovoltaic (FPV) technology is still in its infancy, so our dedicated renewable energy consultants can work with you to provide market-leading support for your project.
With hydrogen considered a cornerstone of the global energy transition, we’ll work with you on full life-cycle projects across production, storage, and transportation.
Our Services
Our extensive legacy as renewable energy consultants has allowed us to expand our service offering continuously. With experience across the board, we can tailor our services to your specific renewable energy project – and achieve exceptional results together.
Our practical experience in offshore wind markets globally positions us to support you with early-market studies, including regulatory compliance and route-to-market strategy.
Our technical studies can be applied at any stage of a project or asset’s lifecycle, supporting decision-making and maximising your performance.
Mitigate risks across your renewable energy project. We can work with you to foresee every aspect of your project, eliminating the risk of delay and unplanned costs.
Having a comprehensive view of your project is key for success. As your dedicated renewable energy consultants, we’ll provide an expert objective perspective to guide decision-making.
Utilise decades of renewable energy engineering experience in your next project. We’re focused on delivering, operating, and financing your energy projects at a competitive price point.
