(Bloomberg) — President-elect Luiz Inacio Lula da Silva has selected a senator and former Petrobras official to lead Brazil’s state-controlled oil giant with the aim of turning it into a renewable energy powerhouse.

Jean Paul Prates, a senator for Lula’s Workers’ Party, confirmed Lula’s invitation in a note sent from his press office. Moments later, Lula congratulated Prates on Twitter, emphasizing that he’s an “expert in the energy sector.”

He will take over a company that’s been criticized for showering investors with record dividends while failing to invest enough in oil refining, wind and solar. Prates has said Petrobras’s current management is steering the company “off a cliff” by narrowly focusing on oil and gas and neglecting the energy transition.

In recent years, Petrobras has won praise from investors for focusing on its most profitable oil projects in deepwater of the South Atlantic, while selling off lower-margin assets such as pipelines, refineries and mature oil fields on land.

The strategy has allowed it to slash its debt and ramp up dividend payments. Financial markets are concerned profits will plummet under Lula as he directs the company to invest in other areas more aligned with his wider industrial policies.

“All oil companies are turning into energy companies, and it isn’t just talk,” Prates said at a press conference earlier this month. “None of this is happening at the right scale at Petrobras.”

Prates was a point person on Lula’s energy team during the campaign and was in charge of talking to investors about oil and energy. He worked in Petrobras’s international division in the 1980s, then became an oil consultant and helped draft legislation in 1997 that removed Petrobras’s monopoly on exploration.

In an August interview, Prates said Petrobras under Lula would reverse years of cost cuts, spend big on refining and renewables, and rebuild international operations that were curtailed in recent years. Within 30 years he sees the company investing as much in clean energy as it does in fossil fuels.

Lula is also expected to revamp local content rules, or the percentage of goods and services for oil projects that need to be sourced from Brazil in order to boost domestic employment. Any increase in that percentage would be a concern for the oil industry because similar policies have led to cost inflation in the past.

In a statement, Petrobras said that the company had not been formally notified about Prates’s appointment and emphasized that Lula’s nominee is subject to internal governance procedures and the approval of the board.
