BPI Building Science Principles (BSP) Certificate launches in two weeks

About this course

This course is one of four free courses included in the Inflation Reduction Act: Solar Provisions Explained Series by CollectiveSun.

The Inflation Reduction Act (IRA) introduced a new tax incentive called the Low Income Communities Bonus Adder.

This adder is unique in that only 1.8GW are allocated per year. If the bonus adder application is approved, the 10% bonus adder is added to the base 30% Investment Tax Credit (ITC) creating a 40% ITC.

The Low Income Communities bonus adder is meant to stimulate more solar adoption in Low to Moderate Income (LMI) communities. In this free course, the team of experts at CollectiveSun will describe how eligibility is determined and the process for how to apply.

In this 60-minute session, we will also review the 4 different categories of allocations described in the Final Regulations released by the Treasury Department, as well as insights on how the selection process will operate.

This webinar originally aired on September 21st, 2023.
