Duyen Hai Power Station is a 4400 MW complex of under-construction coal-fired power plants located in Duyen Hai District of Tra Vinh Province in Vietnam. It consists of Duyen Hai 1, Duyen Hai 2, Duyen Hai 3 and a seaport coal terminal. The complex is designed to be the largest coal-fired power plants in Vietnam, aimed at supplying power for the most regions of Vietnam and reducing the risk of power shortages while boosting economic growth.

Our services

1.Establish illumination standards, provide lighting budget.

Most of power plant projects feature huge investment with lots of technical documents. Illuminance requirements and lighting budget are not a matter of concern to the owner or the contractor. Unclear illumination standards result in different budgets of lighting fixtures. OKTECH establishes illumination standards for power plant in accordance with international standards, selects the appropriate models, carries out design works as well as provides a lighting budget to the owner.

2.Provide lighting solution and material list.

Design works of the large-scale project are always supervised by a consultant firm with strict standards. Illuminance calculation should be required when Illumination layout drawings are provided. Design institutes need more time to prepare design data as they are not familiar with illumination simulation software, thus design schedule may be delayed. OKTECH can provide illuminance calculation and material list to assist the design institute in working out design data.

3.Optimize lighting solution, save cost budget.

As for the illumination layout drawings which had been completed, OKTECH may offer illuminance simulation services based on the drawings by using our simulation plugins of lighting fixtures, and then propose an optimized lighting solution. By utilizing innovative solution from OKTECH, the owner is able to enjoy a savings of approximately 15 percent on quantity of lighting fixtures while still fulfilling the design requirements.


4.Handle goods inspection, certificate of origin, save lead time, control commercial cost.

Our light fittings are supplied with certificates of origin for easy import and export tax refund.

5.Provide guide to installation, work for acceptance.

Mounting specifications (CAD files) can be provided as required by the users. The specifications offer details about mounting styles, dimensions and accessories, suitable for use as instructions for on-site installation works as well as project documents for future reference.
