From overhauls to building firming energy assets

When Jenny Heit joined Callide Power Station for a two-week stint working on overhauls in 2014, she didn’t imagine she’d be part of the team bringing CS Energy’s first firming assets online 10 years later.

“I first joined CS Energy for a two-week backfill position at Callide Power Station, and my contract was extended with the engineering team soon after – and then I moved into overhauls for six years,” Jenny said.

“I had always enjoyed working in projects so when the opportunity came about to join the projects team at CS Energy, I went for it.

“Come early 2022, someone I’d worked closely with during my time at Callide reached out to me about a role to work on the Chinchilla Battery project.

“Working on an entirely new asset – the first new asset in 17 years for CS Energy – was something I knew I couldn’t pass up. The Chinchilla Battery came online in 2024, and we’ve recently had the Greenbank Battery come online as well.

“I couldn’t have guessed this career path 10 years ago!”

Transferring skills across CS Energy's assets

With a range of skills under her belt including financial management and planning and delivering projects, Jenny has applied and built on these skills in her roles and used them widely across CS Energy.

“My years working in overhauls and projects has really helped me throughout my career at CS Energy,” Jenny said.

“It’s reinforced the importance of getting the fundamentals right. I had a handle on financial management after being in the project space, so I used that knowledge to help me develop an understanding of forecasting.

“These are well-rounded attributes that I’m thankful to have learnt early to support my career.”

After first stepping in as Cost Controller, Jenny progressed into her role as Project Controls Manager (acting) where she led a team and oversaw cost, schedule, risk, and document control of future energy projects.

“Being able to progress in the team meant I’d worked in the roles I was leading and could offer valuable help and solutions. This was really important since we were such a small team at the beginning – I’d had exposure to a lot of the inner workings and day-to-day project requirements across controls.”

Jenny expanded her skills further while on maternity leave, returning to university to complete a post-graduate diploma in project management, graduating with high distinction.

“I was able to do this with the support of CS Energy and my mentors in the business,” she said.

Jenny's current role has her overseeing Project Controls in new asset builds, as well as sustaining capital portfolio.

Recently, she co-presented at a project management conference, sharing how innovative project management tools have enhanced efficiency in the team, and other areas of the business.

“I’m looking forward to my next challenge and to see how we can better support and deliver projects at CS Energy.”

Applying learnings to the Greenbank Battery

Jenny said that working on the Chinchilla Battery was a great learning experience which has created a solid foundation of knowledge that can be used for future projects.

“It really helped us going straight into the Greenbank Battery project,” she said.

“It wasn’t quite a rinse and repeat, but there were a lot of similarities and considerations that we knew going into the project.

“For example, we knew what questions to ask, we had a good understanding of what connection looks like with the Australian Energy Market Operator and Powerlink – and now we know what to expect for future assets, too.

“We’ve also learnt a lot about the needs of other teams within CS Energy – such as Trading – and we can involve them much earlier so that we better understand their needs and make things easier for them once new assets are up and running.”
