Tema Embedded Power Project (TEPP) 20MW Thermal


Unlike the conventional power generation system where power generated is evacuated onto the National Interconnection Grid, Corks Energy’s Embedded Generation is evacuated directly onto the off-takers distribution systems of which the output is distributed & utilized locally


CEL has entered into the following key contractual arrangements. These include; Power Purchase Agreement (PPA) with Electricity Company of Ghana for the Plant’s output, site lease, Engineering Procurement and Construction (EPC) contract with a reputable engineering and construction firm, Operational contract with an operator for the Operation and Maintenance of the plant and Direct Agreement.

The PPA was signed on February 12, 2016 between ECG and CEL (Tema Embedded Generation Project), with Tariff-Approved by PURC for both HFO & Gas


Is a proposed 20MW Embedded Thermal Power Plant (TEPP) to be located in Tema. It’s located to the east of Tema industrial area in the Greater Accra Region & close to the Tema Oil Refinery. Features and advantages of the site that dictated its selection are; adequacy and availability of land space, minimal social impact, and fuel supply infrastructure. It’s flat and well compacted and is generally well drained.

The site is already demarcated as an industrial zone which is well developed. The land is already walled for the project and therefore requires no resettlement of dwellings. Accordingly, minimal social impact and disruption is expected from implementation of the Project.


The advantage of Embedded power generation as compared to the conventional power generation is in the evacuation of power to the customer directly void of the national grid, which creates disturbances to the system


  • Reliable low-cost power
  • Power availability & reliability
  • Minimal power losses during evacuation
  • Avoidance of erratic power supply from the national grid system


The technology being considered comprises a natural gas & Heavy Fuel Oil (HFO) / Distillate Fuel Oil (DFO) fired caterpillar CM46DF 50Hz engine. They are in operation all over the world and a number of Independent Power Producers are considering this technology for their projects. 

The “CM” class technology is considered the most suitable technology because of its wide use and easy availability of trained manpower from Caterpillar. The unit size of about 10MW does not pose any security risks to the distribution system as efficiency, availability and output have been improved. Its auxiliaries will be designed and integrated to include all cooling, fuel, exhaust, air connections, control and instrumentation systems required to operate and monitor the engine-generator set system.   

For evacuation of power generated, it can be done through the ECG Tema BSP / Smelter II BSP or through the ECG OLAM substation which are along the project site in Tema.

Fuel supply to the site will be along the RoW of Tema Oil Refinery (TOR) to the on-site fuel storage tanks with treatment systems

It will receive reliable, affordable & high spec of LNG (gas) from its sister gas company, corks gas, to be used for the operations of its 20mw embedded thermal power plants
