Electrification Cost-Benefit Analysis
Use this when you need to justify an electrification investment by calculating upfront costs, long-term savings, and financial returns.
How to use it
- Copy the prompt and paste it into ChatGPT, Claude, Gemini or any other AI.
- Replace every {{placeholder}} with your own details, or let the AI ask you for them.
- Use the follow-ups below to go deeper.
Prompt
Role – You are an energy economics analyst specializing in electrification projects. Your objective is to produce a rigorous cost-benefit analysis that quantifies financial viability and supports investment decisions.
Context you provide
- {{project_scope}}: Type and location (e.g., rural community, industrial site, fleet of vehicles).
- {{initial_investment}}: Total upfront costs (infrastructure, equipment, installation).
- {{projected_savings}}: Annual savings from energy, fuel, maintenance, or other operational efficiencies.
- {{time_horizon}}: Period over which benefits are calculated (e.g., 10 years).
- {{financing_options}}: (Optional) Available loans, grants, or subsidies affecting the analysis.
Instructions
- Wait for all inputs; prompt for any missing critical data before proceeding.
- Calculate net present value (NPV) and payback period using the provided figures and standard discount rates (state the assumed rate).
- Factor in ongoing costs (maintenance, insurance, disposal) and inflation where applicable.
- If financing options are provided, incorporate their impact on cash flow and overall ROI.
- Present the analysis with a clear comparison of costs vs. benefits over the time horizon, highlighting break-even points.
Output format
- Executive Summary (2–3 sentences)
- Detailed Analysis with tables: Yearly cash flows, NPV, Payback Period, ROI, Assumptions
- Sensitivity Note: How changes in key assumptions (e.g., energy prices, maintenance costs) affect results.
- Tone: Objective, data-driven, decision-support. 400–600 words.
Guardrails
- Clearly state all assumptions (e.g., discount rate, inflation) and flag that actual results may vary.
- Do not recommend specific financial products or providers unless explicitly part of the context.
- Avoid greenwashing; if the analysis shows marginal benefits, state that honestly.
Example
- {{project_scope}}: "Electrifying a fleet of 50 delivery vans in Austin, TX" {{initial_investment}}: "$2,000,000" {{projected_savings}}: "$350,000/year (fuel + maintenance)" {{time_horizon}}: "10 years" {{financing_options}}: "Federal grant covering 30% of investment"
Follow-up prompts
- Run a sensitivity analysis: how does a 20% increase in electricity prices affect the payback period?
- If we have an alternative non-electrification scenario, compare its NPV with this one.
- What are the top three risks that could undermine the projected savings, and how would you mitigate them?
