Already a leader in wind energy, Iowa wants to expand its renewable energy portfolio even further. The Iowa Economic Development Authority granted $200,000 to Ideal Energy in Fairfield last month to study “solar plus” systems, solar arrays enhanced with energy storage capacity via batteries.

Without the addition of batteries, these solar grids would only supply power when the sun was shining. The batteries can supply power during outages and at night, and help “shave” energy bills by supplying energy at peak demand hours, when utility costs are highest.

Ideal Energy is currently building a large, 1.1 megawatt solar array with a 1.1 megawatt hour vanadium flow battery for the Maharishi University of Management in Fairfield. This is the largest solar plus project in the state of Iowa and will cover about a third of the university’s annual energy needs.

Ideal is also installing a somewhat smaller array with a lithium-ion battery at the Agri-Industrial Plastics Company in Fairfield. The battery will provide nighttime power for the company’s 24-hour production lines and save them an estimated $42,000 annually.

With the Iowa Economic Development Authority grant, Ideal will assess and compare the performance, efficiency and maintenance of both systems in partnership with Iowa State University’s Electric Power Research Center. A statewide committee, established by the 2016 Iowa Energy Plan, will evaluate the research to inform future solar plus projects in the state.

This weeks segment looks at prospective plans for India to open the first fully solar-powered airport.

Transcript:

India is set to open the world’s first fully solar-powered airport.

This is the Iowa Environmental Focus.

Cocin International Airport is the largest and busiest airport in India’s Kerala state. The transition from traditional electricity to solar power started in 2012, when the price of electricity jumped significantly.

Currently, the airport uses solar panels to generate more than twenty-nine point five megawatts of energy, enough to power the airport with surplus electricity even during the cloudy and rainy monsoon season.

The airport in Cocin is just one example of the growing influence solar power has on India. As much as 10% of expenses in airports come from the amount of electricity used, and implementing more renewable sources of power would help decrease both the carbon footprint and these expenses.

Solar power has been a growing industry in India for some time. The country recently proposed dramatically increasing their solar energy output, proposing to implement enough new panels to generate 100 gigawatts of power. There are some doubts about the ability to meet this goal as India still struggles with its infrastructure.
