Control System Retrofit
The Power Generation Company of Trinidad and Tobago was formed on 24 December 1994.
This date saw the separation of the power generation function from the transmission and distribution functions which were retained by the predecessor company T&TEC.
The ownership of Power Gen is as follows:
Mirant Corporation 39%
bp Business Dev 10 %
The Mirant Corporation has the day-to-day responsibility of managing the company.
The company owns three generating stations on the twin-island republic of Trinidad & Tobago:
Port-of-Spain B Station 320 MW
Pt.Lisas Power Station 630 MW
Penal Power Station 226 MW
Total installed capacity 1176 MW
A Power Purchase Agreement presently sets the legal framework for capacity availability and delivery of generated power to T&TEC’s T&D facilities.

The original company Hawkker Siddeley Dynamics Engineering developed the Digicon ACE system which is presently installed on our machines.
British Aerospace , who bought Hawkker Siddeley kept the intellectual property rights to the name ,”Hawkker Siddeley DynamicsEngineering”
Who is HSDE? (cont’d)Vosper Thornycroft Controls bought the Controls Dept of Hawkker Siddeley from British Aerospace but had no access to the name.Hence “HSDE” is just four initials.HSDE Inc is the North American subsidiary of HSDE LTD of the UK whose parent company is Vosper Thornycroft Controls.
