Environmental action group World Wide Fund for Nature-Philippines (WWF) on Friday dismissed fears over the possible negative impact of adding 500 megawatts of wind power to the national grid.
In a statement, WWF-Philippines Climate Change Unit Head Atty. Gia Ibay said adding 500 MW of wind power to the national grid will have no negative impact on national grid operations, citing a 2013 World Bank and Australia AusAid report on the Grid Impact of Variable Renewable Energy (VRE) for the Philippines.
“Despite wind’s variable nature, 500 MW can easily be integrated without the risk of blackouts or interruptions,” Ibay said.
“A country’s national grid should have a power reserve capacity equal to or larger than its biggest power plant. This reserve prevents blackouts, even if the grid’s biggest plant shuts down. The 500 MW of wind provided by new wind farms in Ilocos, Rizal and Panay, is smaller than the grid’s reserve requirements, so even with their variable nature, they will not affect the grid negatively,” the official said.
Ibay stressed that there will also be no grid constraint problems regarding the time of day that wind farms feed energy into the system because wind production peaks from 11am-2pm and 6pm-9pm—the hours with the highest daily peak demands.
“This means that all generated energy will be consumed. This dispels fears of creating ‘over-contracted’ energy which goes to waste,” she said.
About 70 percent of Philippine electricity is currently generated from fossil fuels, 90 percent of which are imported at varying prices.
Humanity’s continued reliance on fossil fuels for the transportation and energy-generation industries is the primary cause of climate change, the impacts of which are becoming more destructive yearly, WWF said.
Climate solutions-provider WWF is spearheading the Seize the Wind campaign to increase the Feed-in Tariff (FiT) allocation for wind energy from 200 MW to 500 MW before the end of summer. Wind produces free, clean power throughout the year with the highest production during November to April’s Amihan season, the group explained.
The Seize the Wind campaign fully supports the construction of new wind farms to augment the national power supply and overcome the country’s power deficit. About 400 MW of wind power is expected to be added to the national grid by April 2015.
