March 28, 2019Conclusion of MOU on Collaboration for improvement of plant
efficiency with B.Grimm and Siemens
Toshiba Plant Systems & Services Corporation (hereinafter “TPSC”) has concluded amemorandum of understanding (hereinafter “MOU”) for Collaboration with a plant owner
B.Grimm Power PCL (hereinafter "B.Grimm Power") and gas turbine generator manufacturer
Siemens. TPSC, B.Grimm Power and Siemens will mutually study on the better efficiency, higher
availability and digitalization of existing combined cycle cogeneration power plants (hereinafter"CCPP") located in the Industrial Estates in Thailand.
As an EPC*1 contractor, TPSC has successfully completed the construction of a total of nine
power plants for B.Grimm Power on schedule and all of the plants are currently undercommercial operation. A portion of the electric power produced at these sites is sold to theElectricity Generating Authority of Thailand (EGAT), while surplus electricity and generated
steam are supplied to consumers within the industrial complexes. These three companies have
now concluded an agreement to investigate and collaborate on measures aimed at improving
operating efficiency, improving reliability, and plant digitalization at these plants, andimplement them sequentially.
Since 2015, TPSC has introduced digitalization of the engineering process in EPC projects,
called “TIET”, TPSC Integrated Engineering Tool, and further developed plant simulators (DigitalTwins). Going forward, TPSC aims to further improve efficiency of the plants, and improveavailability incorporating IoT*2 to the actual plants, collecting the operating data into the cloudand deploy CPS*3 technologies. in order to provide a stable supply of power and generatedsteam.
The conclusion of this MOU with B.Grimm Power and Siemens will provide uniqueperspectives and knowledge of the power producer, machinery supplier, and EPC contractor for
innovative initiatives to further digitalization. Carrying out development from the different
positions of the three parties makes it possible to achieve extremely convenient and serviceable
systems for power providers.

*1 EPC:*2 IoT:*3 CPS:

A turnkey contract which includes Engineering, Procurement, and Construction & Commissioning.
An abbreviation for "Internet of Things", which refers to connecting a variety of devices to the Internetand carrying out evaluation of conditions, remote operation, and more.
