Wärtsilä supplies 50 MW power plant to help integration of solar energy in Hawaii
(Thomson Reuters ONE) -
Wärtsilä Corporation, Press release, 27 October 2014 at 8.30 am EET
Wärtsilä will supply a 50 MW Smart Power Generation power plant to Hawaiian
Electric Company on the island of Oahu. The plant will help enable the
integration of more solar photovoltaic (PV) generation on the island. The
project requires approval by the Hawaii Public Utilities Commission. If
approved, the power plant is scheduled to be operational in 2017.
"We need to transform our generation portfolio to be more flexible and quick-
starting in order to integrate more renewable energy, especially solar power.
This project is an important step in that direction," said Jack Shriver,
Hawaiian Electric senior engineer. "Internal combustion engines (ICE) provide a
solution to our requirements, since they are fast-reacting, efficient and
capable of running on multiple fuels," he added.
The power station will run on a biofuel blend, which will include liquid fuels
and natural gas when liquefied natural gas (LNG) becomes available on the
island, and it is part of the plan to reduce the island's reliance on oil and
coal-based generation. The plant will consist of six Wärtsilä 34DF engines with
combined output of 50 MW. The power plant will be located on Schofield Barracks
Army base, about 40 kilometres from Honolulu.
Solar PV capacity is growing exponentially in Hawaii. According to the
Interstate Renewable Energy Council, Hawaii has the highest per capita installed
capacity of PV systems in the United States, 255 watts per person. The US
average is 37.9 watts per person. About 12 percent of all single-family
residential dwellings have solar panels in Hawaii.
The official goal for Hawaii is to grow the share of renewable electricity from
15 percent in 2015 to 25 percent in 2020, and 40 percent in 2030. However,
Hawaiian Electric is already over 18 percent, exceeding the 2015 goal, and the
company recently filed a plan that would exceed 65 percent by 2030. "In order to
succeed in this we need fast-reacting capacity. ICEs are a key aspect to that.
We can start them up multiple times daily, reach full load in less than 10
minutes, and shut them off whenever we don't need them. As the amount of solar
power on the island continues to increase, we will reach the point where during
sunny days, we will need to ramp down our existing steam units more than they
were designed to do," Shriver said.
"Solar energy comes and goes. You need something fast to fill the gaps,"
Wärtsilä's Regional Director Wayne Elmore said. "We are thrilled to see, once
again, that our Smart Power Generation technology is a perfect companion to
variable renewable energy. Fast back-up capacity not only supports but enables
much more wind and solar. This is key to sustainable power systems."
Wärtsilä has a long track record of balancing the output of wind farms with
power plants in the Continental US. The latest project is a 225 MW wind-
integrating power station under construction in Oregon, scheduled to go online
in early 2015. Wärtsilä's total installed power generation capacity in the
United States is some 2400 MW. In Hawaii, Wärtsilä has previously supplied two
power plants to the islands of Kauai and Maui with a combined capacity of 38 MW.
According to a recent report by the International Energy Agency (IEA), ICEs are
a promising technology for supporting wind and solar energy. Comparing different
flexibility resources for power systems, the IEA report says that gas-fired ICE
power plants are a "very mature technology" and "cost-competitive to OCGTs"
(Open Cycle Gas Turbines). The IEA notes that "growth in ICE plants actually
exceeds that of turbine-based technologies". According to the IEA, the key
asset of engine-based generation is its fast starting and ramping capability.
Quick reaction time is essential in order to follow the output of wind and solar
as closely as possible. The findings were published in the IEA's Energy
Technology Perspectives 2014.
