The 40.5kW photovoltaic array at Mi Casa is the result of a close collaboration between public, private and nonprofit resources with the support of the Governor’s Energy Office.
“This project is a perfect example of public-private partnership where multiple goals are accomplished - carbon emissions and fossil fuel consumption are offset by electricity generated from renewable sources, private investors supply capital to jump start projects that would otherwise be delayed or never happen; and local jobs are supported for installation labor, engineering and design,” says Doug Wells, President of Renewable Energy Ventures, the private firm investing in Mi Casa’s solar array as part of a power purchase agreement.
Christine Marquez-Hudson, CEO/Executive Director of Mi Casa, adds: “Mi Casa’s solar energy – as well as energy efficiency upgrades performed in anticipation of solar – offset increasing energy bills, and the cash savings will help sustain Mi Casa’s career training programs that assist workers with limited skills and education to launch promising careers in growth industries, including jobs in energy efficiency and renewable energy.”
Mi Casa’s 40.5kW solar array will produce an estimated 53,330 kWh per year, which will offset roughly 24% of Mi Casa’s total energy consumption. Mi Casa also invested in wide-ranging energy efficiency performance upgrades to maximize the savings from solar energy. Through Energy Outreach Colorado, Mi Casa was wrapped the hot water heater, installed a direct digital control system, replaced six old AC units with Energy Star units, insulated HVAC equipment, and replaced 112 light fixtures and ballasts with CFL bulbs and energy efficient ballasts at the agency’s headquarters at 360 Acoma Street.
The partnership with Renewable Energy Ventures, which allowed Mi Casa to take advantage of both the federal tax credit for renewable energy, as well as the Xcel Energy Solar Rewards Rebate, which was recently scaled back. Renewable Energy Ventures will own, operate and maintain the solar array; Mi Casa will pay a subsidized rate for the energy it produces.

A power purchase agreement (PPA) is an operating agreement whereby a third party entity can own and operate a solar array located on a host property. In other words, the building owner provides the location and the system provider installs, owns and operates the array. The electricity generated by the array is then sold back to the property owner. This type of arrangement allows renewable energy through solar to be implemented with reduced or no capital expense on the part of the property owner. Capital costs are recovered over time with the electricity generated.
