11. 11 www.energycenter.org MASH Program - Goals 1.Stimulate adoption of solar power in the affordable housing sector 2.Improve energy utilization and overall quality of affordable housing through application of solar and energy efficiency technologies 3.Decrease electricity use and costs without increasing monthly household expenses for affordable housing building occupants 4.Increase awareness and appreciation of the benefits of solar among affordable housing occupants and developers

12. 12 www.energycenter.org MASH Program- Structure Different incentive for: common area meters$3.30/Watt-AC tenant meters$4.00/Watt-AC Program required at least 20% of incentive dollars to go to offsetting tenant load Solar Costs about $6-8/Watt-AC

13. 13 www.energycenter.org Virtual Net Metering MASH Program- Structure

14. 14 www.energycenter.org What is Net Metering? Net metering is a method of “banking” excess electricity credits.

15. 15 www.energycenter.org How does Net Metering work? -Producing more than consuming (spinning the meter backwards) -Consuming more than producing (spinning the meter forward)

24. 24 www.energycenter.org MASH Program - Challenges Capital constraints Regulated rents limit cash flows to property owners- utility allowance adjustments difficult for retrofits

27. 27 www.energycenter.org MASH Program - Strategies Large incentives helped bring solar providers to the sector

28. 28 www.energycenter.org CA Solar PV Incentives Solar Incentives Existing BuildingsNew Construction MASHCSINSHP Common Area Load $1.90/Watt -AC$0.25/Watt -AC$2.97/Watt -AC Tenant Load$2.80/Watt -AC$0.25/Watt -AC$3.15/Watt -AC

29. 29 www.energycenter.org MASH Program - Strategies Large incentives helped bring solar providers to the sector Marketing, Outreach, and Education Educated contractors and used their marketing channels Reached out to affordable housing sector through conferences/workshops/trade association meetings Gave property owners and contractors tools to educate lenders/ financing partners

31. 31 www.energycenter.org MASH Program - Strategies Large incentives helped bring solar providers to the sector Marketing, Outreach, and Education Educated contractors and used their marketing channels Reached out to affordable housing sector at conferences/workshops/trade association meetings Gave property owners and contractors tools to educate lenders/ financing partners Program progress has relied on a relatively small core of motivated property owners/managers and solar contractors (early adopters)

32. 32 www.energycenter.org MASH Program – Lessons Learned Marketing, Outreach, & Education Leverage contractors’ marketing channels for M&O Flatten learning curve for property owners and lenders through targeted educational efforts Don’t “over-incentivize” PV dedicated to common area meters Meaningful energy efficiency requirements can increase participant/utility/societal benefits

33. 33 www.energycenter.org Considerations for DC Characterize your affordable housing building stock and market as it relates to solar: Electricity usage and costs Roof to living space ratio Metering- Master metered or individual tenant meters Consider a variety of models, community solar, on- site solar Foster cross program collaboration with energy efficiency efforts Evaluate other technologies- SWH, Fuel cells
