Energy Storage Could be Solution To Solar PV-related Blackouts in The Philippines

In Visayas, one of the three main island groups in The Philippines, too much solar on the grid may lead to blackouts during the election period, which begins today, March 28, and lasts until May 7. 

Grid operators are concerned that too much power is being fed into the grid when all of the solar PV plants in the region are churning out electric power along with the geothermal and coal plants in the region — even if the geothermal and coal plants are dialed down to their minimum load requirements.  Further the swings in power supply due to intermittent PV generation (from 20 to 50 percent) have already caused grid interruptions.  

Visayas does not have any frequency regulation providers to help balance the grid and absorb excess capacity and the National Grid Corporation of the Philippines and the government are exploring the use of energy storage and potentially hydro assets to help solve the problem. 

Meanwhile in the U.S. the Energy Storage Association on March 28 is launching its new #StorageIsHere campaign in an attempt to bring more visibility to the technology that it says is already “booming.” 

The articles below offer more detail on both stories.

How Much Noise Would a Wind Farm Make if a Wind Farm Could Make Noise?

That’s the question that researchers in Australia are trying to answer with a new $2.2 M study funded by the National Health and Medical Research Council (NHMRC). The study is focused on something called “wind turbine syndrome” which, according to people who suffer from it, causes dizziness, sleeplessness and headaches. 

Some believe that the syndrome is psychosomatic, sending the message to the people who claim they have it that, “it’s all in your head.”

The scientific community isn’t sure it’s a such a good idea to spend quite so much money this topic but the two researchers conducting the study would like some scientific evidence that will shed light on the claim that wind farms are making people sick.

Meanwhile in UK-Scotland border town, Berwickshire Housing Authority (BHA) is building a community wind farm along with partner Community Energy Scotland. BHA builds desperately needed low-income rental housing the UK and the wind farm will be the first of its kind developed by a housing authority in the UK.  The wind farm’s three turbines should be connected to the grid by April of next year. What is unique about the project is that the revenue from the sale of the wind energy will pay for BHA to build more of its low-income homes.

Palm Trees Inspire UVA Team’s Revolutionary Design for Offshore Wind Turbines

In 15 years, a forest of giant wind turbines – able to protect themselves in severe weather by folding in their rotor blades like palm trees in a hurricane ­- could be planted off the coast of Virginia, delivering enough energy to power as many as 500,000 homes, thanks to research that has earned a $3.56 million federal grant for the University of Virginia School of Engineering and Applied Science.
