Strategic objectives and stakeholder alignment
Focuses on providing base rate stability for customers while supporting economic development and growth.
Reflects collaboration with stakeholder organizations, balancing financial benefits for both shareowners and customers.
Achieved a non-unanimous settlement through engagement with various intervenors, maintaining a constructive regulatory environment.
Key financial and operational terms
Cost cap set at $3,020/kW, including AFUDC and transmission, with recovery limited to actual costs incurred.
Ratemaking principles apply for up to 1GW of new wind generation, with a 40-year depreciable life.
Allowed ROE for ESM calculation matches IPL's blended ROE (currently ~9.9%), updated annually.
AFUDC rate based on IPL's non-advance ratemaking ROE, currently 9.65%.
Tax benefits and energy margins retained until investments are included in customer rates, aligning economic benefits.
Settlement mechanics and regulatory process
Any capital costs above the cap are included in ESM at IPL's non-advance ratemaking ROE until prudency is determined.
Capitalized maintenance excluded from the cost cap; prudency review required for costs above the cap.
Wind generation not qualifying for 100% PTC must be demonstrated as prudent and cost-effective in annual reports.
Project benefits, PTC sales, and REC sales are recorded above-the-line but excluded from energy adjustment or other cost recovery mechanisms.
All costs and benefits included in the earnings sharing mechanism until the next retail electric rate case.

One of the very few apps you could call perfect. If something was to add to it, maybe the share price of the company when you search for it, but it's already excellent.
