The company said the growing interest in renewable technologies meant a change was needed in how its wind business was operated.
Vattenfall Wind now has three business units: onshore, offshore and photovoltaic and storage.
"We face a fast changing business environment in our markets. With the creation of a lean business model with product lines in order to create dedicated end-to-end-processes and business that can respond to different markets, we take the logical next step to fulfil our ambitious targets", said Vattenfall Wind head Gunnar Groebler.
With the launch of the three units at the start of July, Vattenfall appointed three unit leads to work under Groebler.
Michael Simmelsgaard will lead the offshore unit. Previously he was vice-president of strategic projects and partnering at Vattenfall, after also holding roles at Dong Energy and Siemens Wind.
Sandra Grauers-Nilsson will be head of the onshore wind business unit, and Claus Wattendrup will lead the photovoltaic and batteries unit, a first for the group.
"An important new pillar of Vattenfall's renewable strategy is the formation of the business unit photovoltaics & battery. In the upcoming two years, Vattenfall plans to invest up to €150 million in large scale as well as decentralized PV and battery projects," Groebler said.
The wind division was formed in April 2015 following a major restructuring.
Vattenfall said it operates approximately 2.5GW of wind across five markets in Europe, with a plan to reach 4GW by 2020.
