Key Topics Covered
E&P Valuation: NAV, Decline Curves & Reserve Risking
Explains why terminal-value DCFs are inappropriate for depleting resources, how to build a bottom-up NAV from individual wells, and the risking framework that discounts PDP at 100 percent down through Possible reserves at 10 to 40 percent, which is often the primary driver of bid-ask spreads in A&D negotiations.
EBITDAX, Reserve-Based Lending & Commodity Benchmarks
Covers why EBITDAX normalizes the Successful Efforts versus Full Cost accounting divergence, how reserve-based lending ties borrowing capacity to 1P reserve value with semi-annual redeterminations, and the key benchmarks including WTI, Brent, Henry Hub, and regional power prices.
Midstream Contracts & Downstream Margins
Distinguishes Take-or-Pay contracts that provide volume-risk insulation from Fee-Based structures, explains why contract quality drives midstream multiples, and walks through the 3-2-1 crack spread formula that governs refining profitability.
Regulated Utility Economics: Rate Base & Revenue Requirement
Details the Rate Base framework where Allowed Profit equals Rate Base times Allowed ROE, walks through the full revenue requirement build-up from equity return through tax gross-up to O&M, and explains why TEV-to-Rate-Base is preferred over TEV/EBITDA for cross-jurisdiction utility comparisons.
Renewables: YieldCos, Partnership Flips & LCOE
Covers YieldCo structure and CAFD as the key distribution metric, how Tax Equity Partnership Flips allocate tax credits to investors until a target IRR triggers the flip, TEV per MW valuation for development-stage pipelines, and LCOE as the standard for comparing generation cost across technologies.
How to Prepare for Energy, Power & Renewables Interviews
Be able to explain why NAV replaces a terminal-value DCF for E&P companies in a single clear sentence: oil and gas are depleting resources with finite reserve lives, so a perpetuity assumption is physically incorrect. Then be ready to walk through the NAV formula components and the risking framework for each reserve category.
Understand the economic logic behind each energy subsector's risk profile. The sessions show that Upstream is commodity-exposed, Midstream is fee-based with contract protection, Downstream is margin-based on the crack spread, and regulated utilities earn a guaranteed return on rate base. Interviewers test whether you can articulate why valuation approaches differ across these models.
Practice the Rate Base math: if the utility has a ten billion dollar Rate Base, a 50/50 debt-equity split, and a ten percent allowed ROE, you should instantly derive five hundred million in allowed net income. The advanced session includes this exact calculation, and it frequently appears in energy group interviews.
Know the difference between PV-10 and the SEC Standardized Measure and why PV-10 is preferred in banking. The advanced session explains that PV-10 strips out tax differences to enable cleaner cross-company comparisons, while the Standardized Measure uses rigid year-end spot prices that may be anomalous.

About This Energy, Power & Renewables Mock Interview
These sessions span the entire energy value chain. The basic session covers Upstream, Midstream, and Downstream sector differences, integrated majors, Oilfield Services cyclicality, why NAV replaces terminal-value DCF for E&P, decline curves and the treadmill effect, 1P/2P/3P reserve classifications, BOE conversion, EBITDAX normalization, MW versus MWh and capacity factors, the spark spread for gas-fired plants, regulated utilities versus IPPs, YieldCo structure and CAFD, reserve-based lending mechanics, commodity benchmarks, and the energy transition. The advanced session deepens into NAV formula construction and reserve risking across PDP through Possible categories, the Recycle Ratio for capital efficiency, the 3-2-1 crack spread, Take-or-Pay versus Fee-Based midstream contracts, Rate Base and revenue requirement math, TEV-to-Rate-Base as the preferred utility metric, Tax Equity Partnership Flip structures in renewables, TEV per MW for developers, LCOE for cross-technology cost comparison, and PV-10 versus the SEC Standardized Measure.

The IB Vine technical prep is beyond helpful, it's so much more fun quizzing myself every now and then vs. reading through the guides again.

I personally found that the 'IB Vine Select' collection had some of the exact questions I was asked in my Qatalyst interviews.
Analyst
Thanks for starting up IB Vine. Couldn't have landed my offer without your help!

I honestly think you're doing gods work since IB Vine democratizes the whole interview process and helps a lot of students ace their interviews.

I found this website really helpful, which also helps me better prepare for the technical interview in IBD position and get an offer.

Check out IB Vine, specifically the 'IB Vine Select' questions. Once you can get a handle of those, it seems like you are in a spot where you're applying the concepts rather than simply memorizing them
Analyst
I've used IB Vine for my recruitment, and I could not imagine the journey without it. Thank you for creating a phenomenal resource.

Beyond the 400 questions guide, try to understand a deeper level and the underlying concepts of the questions being asked. Use ibvine, it really helps.

IB Vine has excellent questions, especially multistep ones. In my experience I've gotten grilled on accretion/dilution, bond math, and merger model questions. IB Vine has great practice for all of those.

As a nontraditional transfer student who has been rendered unavailable to many resources at my university (Leadership positions at clubs, immediately behind the recruiting cycle, etc.) IB Vine has been an absolute game changer in my IB prep.

From my experience interviewing FT for IB, it’s not enough to just know the 400 questions anymore (it’s a good starting point) but to look at even more advanced questions. Would recommend IB Vine.

heard all the new kids use IB Vine now. the questions on IB Vine helped me get the concepts down when I had to recruit and make a lot of BB/MM interviews easier than I expected for techs
User Story
Just got off the phone with a kid who interned at a Dallas PE firm. He mentioned that IB Vine helped him secure that internship as well as his Summer Analyst offer, especially since he came from a non-target with no resources.
