Confronting Climate Change
Commitment
| University-wide on-site renewable energy studyCommitment | Explore renewable energy purchasing goalSlide4
Energy Supply and Renewables
1 MW of installed solar PV
14% of electricity from renewable sources to meet MA RPS (3% from alternative sources)
Steam Plant fuel switching, equipment upgrades combined with utility efficiencies and demand reduction account for 60% of greenhouse gas reduction to date
Expanded CHP system online in fall 2015Slide5
Complementary Mechanisms
Advisory Group of faculty, students, staff convened by President Faust
Make recommendations to University on use of off-site complementary mechanisms for achieving GHG emissions reduction goal.

Class 1 Renewable (8% of RPS)
Harvard purchases 10% of its energy from Maine wind farm (provides energy +) RECsDEP permits purchase of RECs + energy to be used in establishing one’s own emissions labelWind is variableRequires basis paymentsZonal LMPs may differ

was to help support the installation of new, cleaner technologiesClass 1 represents 8% of RPSSREC 1 2014 - 0.948%, 2015 – 2.144%SREC2 2014 – 0.0843%,2015 – 0.3288%Class 2 supports hydro built prior to 19972.5% of load this yearWTE

Renewable market is establishedNot yet price
competitiveRPS designed to assist technologies to thrive Perhaps this should be more flexible and represent technologies that need the push to get going (storage)
Conclusion
Goal:
Integrate
renewables into the
market
and make
it the technology of choice.Slide15
