Dennis enjoyed a strong showing in the Indonesian double header, qualifying on the front row for the first time since the season opener in Mexico City before going on to finish second in each of the two races.
This made him the second highest points-scorer over the course of the weekend, only behind Race 2 winner Maximilian Guenther of Maserati.
With five races remaining in Formula E’s first Gen3 season, Dennis finds himself right behind Porsche’s Pascal Wehrlein in the standings, having trailed erstwhile leader Nick Cassidy by 25 points going into Jakarta.
The British driver hailed Andretti for delivering a big step-up in one lap performance in Indonesia, allowing him to qualify up front and score the big points he needed in order to strengthen his bid for a maiden title.
“Honestly, just a big thanks to the team,” said Dennis. “That's the biggest thing, [just] how much effort we put in from here to the previous races over qualifying.
“It's really shown and it's really paid off because qualifying in the past few races hasn't mattered all that much but this weekend it's been crucial.
“It really helps to bring my championship back alive.
“We will see whatever happens in Portland. It's completely different from how most FE circuits are, very fast, very flowing.
“There will be lots of overtaking, similar to Berlin and yeah, just some time off now before we go again in a few weeks.”
Another driver who was an outside bet for the Formula E title coming to Jakarta was Jaguar’s Mitch Evans, who had lost a big chunk of points in Hyderabad when his team-mate Sam Bird took him out of the race.
Jaguar was unusually off the pace in Jakarta, with neither the factory team nor customer squad Envision featuring at the front, with Evans’ misery compounded by another crash with Bird in the opening race.
