One island school see the benefits of turning to solar energy and has helped in making the Archdiocese of Agana the largest private consumer of solar energy.
Since 2012 the archdiocese has been slowly reducing their utility bills through the use of solar power and in 2013 the archdiocese became the largest private user of renewable energy on Guam. San Vicente Catholic School in Barrigada continues to demonstrate their commitment to the environment with the installation of a 522 panel system. Finance Council board member John Taitano said, "We had to find ways in order to eliminate our biggest expense our biggest number one expense is utility power bill."
He says that the rising cost of power put a strain on the school's budget. And with the addition of San Vicente Cathloic School the Archdiocese of Agana now has over 500 kilowatts of production in place. This means they are capable of producing 784 mwh per year saving the various entities of the church over $50,000 per year in utility bills. At San Vincente Catholic School Taitano says that turning to solar power has been a wise decision, saying, "Right off the bat this month we have probably saved $1,400 in utility bills electric bills."
Adding that the focus in installing the solar panels was the classrooms which are now cooler and don't pull as much power. This was all possible through using a mechanism called a power purchase agreement the systems have been installed on different roofs within the archdiocese by power providers who contracted with Pacific Solar Photovoltaics to do the design, installation and long term maintenance and monitoring. San Vicente Catholic School in this case is a power purchaser. This type of mechanism enabled the church to make no investment in the project but allows them to receive 20-25% savings on the power produced and sold to the facility. Over time this savings increases as utility rates rise.
Currently there are several projects on archdiocesan schools and churches being proposed for installation this year which will bring their total participation in environmentally safe energy to about 1,000 kilowatts or one megawatt of distributive solar power. Distributive solar generation means that its production is spread over a broad geographical area and much of the energy produced is actually consumed on site where it is produced creating very little impact on utility grids.
