The Challenge

Sustain GRID Auxiliary Services while lowering emissions

The CET Arad power plant produces hot water for a steam-driven turbine and this requires constant power to supply the related ancillaries.

Another essential requirement for the customer was to meet stringent pan-European (ENTSO-E) guidelines.

Combining the two requirements into an efficient and cost-effective solution would require a tried and trusted power partner – with ample experience.

The Solution

An integrated hybrid solution – batteries and gas power

Aggreko were recommended for the job and our experts had to design and engineer an integrated solution to combine power production with balancing services and CO2 emissions reduction.

We devised a package that could produce power from natural gas, while adding batteries to sustain GRID auxiliary services.

We produced thermal energy by capturing exhaust gas and jacket water from gas engines, enhancing the overall efficiency of the solution and keeping emissions in check.

We reinforced the supply from the gas generators with battery storage to provide a hybrid resource that can respond to changes in demand instantly, which kept the frequency stable. This is because our batteries react with millisecond-level precision, which allows our customer to ramp up power to the gas turbines to provide longer-term support – and it means the gas turbines can run at their most efficient level.

The Aggreko Difference

Efficient, adaptable solutions for every situation

The Impact

Higher efficiency with lower costs and emissions

Our rental equipment of energy production and storage are adapted to supply safe power and innovative solutions that preserve the environment.

Our integrated, hybrid solutions are ready to be plugged in quickly, allowing our customer to negate any risks associated with production loss

The power plant can supply the ancillaries services with a comprehensive solution, including a software platform, which optimises costs and stabilises the grid.
