Renewable energy solutions specialist Greenvolt Next, part of Greenvolt Group, is to create 90 jobs - 50 of which will be based at its Waterford headquarters.
The new roles will include project engineers, senior project engineers, project managers and site managers.
Greenvolt said the positions are part of a significant investment into its expansion, talent acquisition strategy and future growth plans.
The company's existing Waterford headquarters is also being increased by 202sq.m and will be equipped with the latest technologies.
Greenvolt Next supports businesses with their renewable energy transformations and its energy projects here include the Sanofi Waterford solar farm. It also works with retailers including Lidl, Aldi and Tesco.
Over the next three years, Greenvolt Next said it is forecasting significant increase in revenue following accelerated market growth on the back of rising demand for sustainable and renewable energy, as well as requirements around CSRD reporting.
Specifically, the organisation anticipates growing demand for solar panel installations and battery storage projects over the next 12 months.
Greenvolt Next said it reduced customer CO2 emissions by 30,000 tonnes last year, with a further reduction of 150,000 tonnes of CO2 projected over the next three years as demand for renewable energy soars.
Greenvolt Next Ireland & UK chief executive Owen Power said the company's success to date has been driven by its ability to deliver the most reliable and cost-effective energy solutions to customers, underpinned by unmatched resources and expertise.
"Looking to the future, which will only see greater demand for such projects, we want to continue making a tangible impact for businesses and the environment," Mr Power said.
"That means investing in operations, growing the team and innovating for customers. As well as marking the next stage in our own journey, this will allow us to make renewable energy easy for more organisations across Ireland and the UK. In turn, they will not only be more sustainable but also more successful," he added.
