sition in El Salvador. "
The EdP project has employed more
than 1,400 workers during construction,
with about 80 permanent jobs
available for the completed project. The
permanent jobs will involve operation
and maintenance of the power plant,
the FSRU, and the accompanying infrastructure.
Invenergy said the EdP project
represents the first permanently
moored FSRU on the Pacific coast of
the Americas.
Carral told POWER the Wärtsilä
4. This floating storage and regasification unit, operated by Invenergy, provides fuel for the
378-MW Energía del Pacifíco power station in El Salvador. Courtesy: Wärtsilä
Community Expert, told POWER, " The
Energía del Pacífico is a major undertaking
with several major steps that required
a substantial amount of work to
materialize. In January 2013, there was
an RFP [request for proposals] issued by
the distribution companies in El Salvador
for 350 MW [of] firm capacity with
proposals to be submitted by October
of that year. " Carral said, " During a ninemonth
period in 2013, there was a great
deal of effort invested in getting the winning
technological solution with a 378MW
power plant based on a combined
cycle with reciprocating engines with
the W50DF engine and the LNG supply.
This combination resulted in the winning
proposal of the bid. However, the gas
supply still needed to be contracted. "
Carral said a tender was launched in
2015 for a 12-year supply of LNG, and in
October 2016, the construction contract
between Wärtsilä and EdP was finalized.
" Subsequently, in 2017, EdP announced
the signing of a contract for the purchase
and sale of natural gas with Shell
International Trading Middle East, " Carral
said. " The next big step in this project
was to get a new majority investor on
board. " Invenergy in 2019 became the
major shareholder of the project.
El Salvador currently imports about
one-quarter of the country's total electricity,
making it the largest importer of
electricity in Central America. Government
officials have said the heavy reliance
on imported power creates energy
security risks, along with providing an
economic challenge. Officials said the
EdP project, expected to supply about
30% of the country's total electricity,
will reduce imports of power to about
5% in 2023.

Carral said additional contracts related
to the project were pursued for different
technology solutions. The FSRU
includes partnerships with BW LNG and
BW Offshore. Saam Towage was contracted
to tow the FSRU to the location;
that company serves customers from
Canada, Mexico, Central America, and
South America.
" The LNG delivered to the FSRU will
be regasified and transported from the
FSRU to the power plant through an
underwater gas pipeline designed and
built by the maritime infrastructure contractor
Boskalis, " Carral said, with the
regasification and power generation
systems onboard the FSRU provided by
Wärtsilä Gas Solutions. " Elecnor was
contracted to install the high-voltage
line, which will be approximately 44 kilometers,
to connect to the Central American
Electrical Interconnection System,
which will strengthen the country's
electricity grid. "
Funding came from several multilateral
financial
organizations, including
the International Finance Corp. (IFC),
Overseas Private Investment Corp.
(OPIC), Finnish Export Credit Ltd., UKbased
KfW IPEX-Bank, and IDB Invest.
Carral said financing was completed in
December 2019, and represents a foreign
direct investment of about $1 billion
for El Salvador-the largest private
investment ever made in the country.
Sampo Suvisaari, Wärtsilä Energy's
business director for Latin America
North, said, " Another unique feature of
this flexible power plant will be the ability
to produce energy efficiently even at
partial loads. This type of project is an
exciting development for us as innovators
and as partners in the energy tranwww.powermag.com
Dry
Flexicycle power plant concept
selected for the EdP project " offers
high-efficiency reciprocating engines "
that are combined with a steam cycle,
with close to zero water consumption.
The plants can be optimized for power
within a range of 60 MW to 600 MW.
Depending on the need, the number
of prime movers (combustion engines)
can vary and any initial investment can
easily be expanded in 10-MW to 20MW
blocks, when needed. Each engine
is equipped with a heat recovery
steam generator and the plant utilizes
a common steam turbine with a radiator-based
cooling system. The solution
is said to offer fast start-up and excellent
load following capabilities, which
are beneficial during peak hours such
as hot summer days. This technology
can also integrate renewable energy,
which is significantly growing in Central
America.
Carral said the project " will allow
El Salvador to become less reliant on
importing energy through the SIEPAC
[Sistema de Interconexión Eléctrica de
los Países de América Central] transmission
line, which offers electricity
to Central America's power grid. " The
SIEPAC line is the electrical transmission
grid that runs from Guatemala to
Panama, connecting the six Central
American countries.
" Historically, electricity generation in
the region has been highly dependent
on hydroelectric plants as well as plants
powered by diesel and fuel oil, " said Carral.
" This matrix has negatively impacted
energy costs and security of supply,
which has caused frequent blackouts for
most of the country. The SIEPAC transmission
system has also presented congestion
problems, which has created
reliability issues for countries that heavily
rely on importing electricity via this
system. The new project will be fueled
by natural gas and will bring the overall
cost of electricity down while providing
firm, reliable power to the country. "
