15-0123 v2.X Surplus On-Site Energy

Question:

Our project is pursuing certification under LBC 2.0, and has just completed its 1-year performance period. In it’s first full year of operation, the building generated roughly 60% more energy than it used from its on-site photovoltaic array.We believe that this onsite solar generation has at least as much value to the community as purchased carbon offsets used to subsidize other renewable energy projects in other parts of the country. The surplus energy from our building is used by the local utility to provide power to our neighboring properties - which has multiple benefits including balancing loads on district level grids and the resiliency and safety that come with decentralized power production.We are advocating that LBC projects with an on-site energy surplus receive credit for the associated carbon offset when calculating the number of carbon credits required to fulfill the requirements for Imperative 12. Please let us know if the ILFI would be willing recognize the avoided CO2 through surplus on-site generation as a viable source for carbon offsets.

Answer:

Yes. The Institute agrees that energy generated by a project, that surpasses the needs of the project and goes back  into a community energy grid, is equivalent to creating a new renewable power project through the purchase of CERs  or VERs. Therefore, the Institute is creating a new Exception: v2.1: I12-E2 Surplus Renewable Energy v3.0: I11-E2 Surplus Renewable EnergyA project's surplus renewable energy, if it is returned to the grid for use by others, can be used to satisfy an equivalent portion of the project's required carbon offsets. The team must document the surplus energy during the twelve month performance period and convert the kWh to tCO2e using the EPA's Greenhouse Gas Equivalencies Calculator. The resulting tCO2e may then be deducted from the project's Embodied Carbon Footprint offset requirement.
