Share this

The Company

InterGen is a global power generation firm with 6 power plants in operation, representing a total generation capacity of 4,630 megawatts (3,337 net equity MW).

These facilities are located in the United Kingdom and Australia. InterGen is jointly owned by China Huaneng Group/Guangdong Energy Group Co., Ltd. and Sev.en Energy (which recently acquired a 50% stake in InterGen from Ontario Teachers Pension Plan).

The Challenge

InterGen required an ETRM system. After a thorough selection process throughout 2018, Energy One was chosen to deliver the system, which has been designed to optimise power trading in the UK.

The Solution

A joint team, including InterGen and Energy One with support throughout from Baringa Partners worked to ensure the most appropriate solution was selected to meet InterGen present and future requirements in an evolving energy market. This process included the design of a new business trading model that will allow InterGen to streamline and enhance their trading and risk management capabilities.

The ETRM provides a full front to back office solution to allow the valuation and optimisation of the InterGen portfolio while providing additional controls, regulatory reporting and improved user experience. The joint team worked together over 10 months to design, develop and test the solution, which culminated in a successful go-live on Saturday 29th June 2019.

The Implementation

The Results

The fully hosted enTrader® system boasts strong real-time position management, key for InterGen in balancing the day to day positions of its three large combined cycle gas plants (totaling 2,560MW) which are all commercially operated from InterGen’s headquarters in Edinburgh.

Throughout the course of the project InterGen adapted its Business Processes to maximise usage of “off the shelf” system functionality but also partnered in developing innovative features that enhanced the core product offering.

We are delighted that the InterGen team, supported by Baringa Partners and [Energy One] have managed to implement the new ETRM system in such an aggressive timescale. The system we have in place is now fully flexible and will be able to easily incorporate InterGen’s growing asset base in the UK, including the new 300MW OCGT at our Spalding site which entered commercial operations last month. enTrader also provides InterGen with better monitoring, regulatory reporting, and optimisation capabilities.
