Interesting article on the value of old landfills as solar-energy sites:

The most valuable distributed generation is located “closest to load”. The closer the power production facility is to the load (where the power can be used), the lower the transmission losses and easier it is to interconnect without transmission upgrades. The problem with locating utility scale PV production close to load is the dearth of affordable sites of an appropriate size.

Using “bad” land that has limited use and little value for other purposes is one way to make it easier to build PV projects closer to load. Brownfields and former landfills are good examples of low cost land that can be recycled to be used for renewable energy cites. Absolutely Solar is currently in preliminary discussions with a solar developer that is working on three closed landfills and with a county government that has similar sites available.

5 old landfills to be studied as solar-energy sites

BENJIE SANDERS / ARIZONA DAILY STAR / January 12, 2012

The old Vincent Mullins Landfill at Speedway and Kolb Road is one site that will be studied for use as a possible solar-energy farm.

The city is aiming to find out whether solar energy farms might be a reasonable use for its old, closed landfills.

Tucson is one of 26 cities across the country selected to work with the U.S. Environmental Protection Agency and the U.S. Department of Energy. Read more
