Wärtsilä and EGE Haina sign natural gas power plant commissioning project & long-term service agreement in the Dominican Republic

Press Release
The technology group Wärtsilä and Empresa Generadora de Electricidad Haina (EGE
Haina), one of the largest power generation companies in the Dominican Republic,
have signed a commissioning agreement that converts the Quisqueya 2 power plant
to natural gas operation.
The 215 MW Flexicycle plant was installed in 2013, and is powered by 12 Wärtsilä 50DF dual-fuel engines.
The engines have been liquid-optimised until now as only heavy fuel oil (HFO) has been available. As natural
gas is soon to become available, and with the execution of this conversion
project, the plant will be re-commissioned to run on gas. The commissioning
project contract was signed in September 2019.

The conversion will lessen the power plant’s environmental impact with exhaust
emissions being greatly reduced. It will also allow the plant to be a major
provider of electricity and ancillary services to the national grid. Quisqueya 2
is a flexible baseload plant operating under a power purchase agreement (PPA),
whereby the utility agrees to supply electricity to the national grid.

“Our company celebrates its 20th anniversary this year with plans to continue
investing in sustainable energy towards 2030 with the development of 1,400 MW of
renewable power generation and natural gas. Switching to natural gas in
Quisqueya 2 is critical to our future operations, both for the plant’s
environmental sustainability and because of the new PPA. We appreciate the
support from Wärtsilä for this important project,” said José A. Rodríguez,
Development Director, EGE Haina.

“Wärtsilä 50DF engines are capable of running on different fuels, so with
natural gas now becoming available for Quisqueya 2 it is time to enable dual
-fuel operation. The re-commissioning is straightforward and the plant will soon
operate with clean natural gas,” commented Sampo Suvisaari, Energy Business
Director, Latin America North, Wärtsilä Energy Business.

The project is expected to be completed by mid-2020.

Long-term service agreement

The two companies have also signed a long-term service agreement covering all
the Wärtsilä power plants owned and/or operated by EGE Haina. The agreement was
signed in October 2019 and runs until the end of 2022. It will allow accurate
predictability of spare part and maintenance costs for the Quisqueya 2, Sultana
del Este, and Palenque power plants. The total installed capacity of the three
plants is approximately 400 MW.

The Sultana del Este plant operates on nine Wärtsilä 46 engines, while the
Palenque plant runs with four Wärtsilä Vasa 32LN engines.

“This agreement allows us to have accurate budgeting for the maintenance and
servicing of these plants, covering both scheduled servicing and unscheduled
repairs. It also enhances the reliability of our electric supply to the national
grid. Wärtsilä has the needed experience, which means that we can concentrate on
our core business,” noted Rodríguez.

“Wärtsilä’s service agreements form an integral part of its lifecycle support
approach to providing efficient, reliable and safe power plant operations. They
facilitate planning and provide predictability of costs, and are tailored to
accommodate the particular needs of the customer. We provide support from our
global network of Wärtsilä Expertise Centres to ensure that potential downtime
is minimised, and these agreements simply make sense in so many ways,” added
Marc Tarbox, General Manager, Agreements and Project Sales in Americas, Wärtsilä
Energy Business.
