Energy: Billing Support and Consumption Tracking with RAG

Energy providers face a paradox: millions of customers, but a primarily transactional relationship centered on bills. Call centers are saturated with recurring questions: "Why did my bill double?", "How do I read my meter?". RAG (Retrieval-Augmented Generation) transforms this relationship by offering intelligent, personalized support.

The Energy Sector Challenge

Massive Volume of Requests

A mid-sized energy provider manages:

• 500,000 to 2 million customers
• 10,000 to 50,000 calls per month
• 80% of calls concern billing
• Seasonal peaks: True-up bills, rate increases

Each call costs $5 to $8 on average. Customers sometimes wait 20 minutes.

Customer Expectations

Consumers want:

• Understand their bill: Clear breakdown of amounts
• Control consumption: Personalized savings tips
• Responsiveness: Immediate answer without phone wait
• Transparency: Explain rate changes

According to a 2025 mc2i study, 45% of French consumers don't understand the breakdown of their electricity bill.

Current Limitations

Existing tools show their limits:

• Static FAQs: Generic answers, not personalized
• Basic chatbots: "I didn't understand your question"
• Call centers: Expensive and overloaded
• Customer portal: Data without explanations

What RAG Brings to Energy

An Advisor Who Knows the Customer File

RAG can access in real-time:

• Consumption history monthly and annual

Permanent Availability

The assistant responds:

• In the evening when customers receive their bill

Concrete Use Cases

1. Personalized Bill Explanation

The problem: "Why did my bill double this month?"

The RAG solution:

Customer: "I got a $287 bill when it's usually $120, is that normal?"

Assistant: "I understand your surprise. Let me analyze your March 15, 2026 bill:

Breakdown of $287:

1. Electricity consumption: $198

• kWh consumed: 1,450 kWh (vs 680 kWh last month)
• Likely explanation: February cold snap (average 18°F)
• Your electric heating consumed more than usual

2. Annual true-up: +$52

• Your installments were based on an estimate of 8,500 kWh/year
• Actual metered consumption: 9,200 kWh
• Difference to settle: 700 kWh × $0.0746

3. Rate change: +$8

• 8.6% increase applied February 1, 2026
• Impact on this bill: +$8

4. Taxes and fees: $29 (unchanged)

Your 12-month average bill: $145/month This bill is exceptional, related to cold weather and true-up.

Would you like me to adjust your installments to avoid a large true-up next year?"

Impact: First-contact resolution rate +60%.

2. Comparison and Savings Tips

The problem: "I consume too much, any tips?"

The RAG solution:

Customer: "I think I consume a lot, any advice?"

Assistant: "Let's analyze your consumption to identify opportunities:

Your profile:

• Home: 700 sq ft apartment, electric heating
• Annual consumption: 9,200 kWh
• Annual cost: ~$1,740

Comparison:

• National average for similar home: 7,800 kWh
• You're 18% above average

Your peak analysis:

• High nighttime consumption (11pm-6am): +25% vs average
• Possible: Water heater or radiators programmed at night?

My recommendations:

1. Switch to Time-of-Use rate (if not already)
   • You consume 40% at night
   • Potential savings: $180/year
2. Set water heater on timer
   • Heat water only during off-peak hours
   • Savings: $80/year
3. Check insulation
   • Your heating consumption seems high
   • An energy audit would be useful

Total potential savings: $260/year

Want me to simulate switching to Time-of-Use rate?"

Impact: Customer satisfaction +35%, advisor image vs simple provider.

3. Assisted Meter Reading

The problem: "I don't know how to read my smart meter"

The RAG solution:

Customer: "How do I read my smart meter? I don't understand the numbers"

Assistant: "I'll guide you! Here's how to read your smart meter:

To display the reading:

1. Press the button on the right side of the meter
2. Information scrolls with each press

What displays:

• 1st press: Your account number (verification)
• 2nd press: Total kWh or Peak kWh
• 3rd press: Off-Peak kWh (if you have Time-of-Use)

Your current plan: Standard Rate

• You only have one reading to note
• It's the kWh number displayed

Your last reading (January 12, 2026): 45,892 kWh

• If the display today shows 46,200 kWh
• You've consumed: 308 kWh since last reading

You can also see your daily consumption on the utility app (free).

Need help with anything else?"

Impact: Meter assistance calls -70%.

4. Payment Difficulty with Empathy

The problem: Customer with payment difficulties

The RAG solution:

Customer: "I can't pay my bill this month, what happens?"

Assistant: "I understand the situation can be difficult. Here are your options:

Your pending bill: $245 (due March 15)

Immediate solutions:

1. Payment plan (most common)
   • 3 monthly payments of $82 with no fees
   • First payment: March 30
2. 30-day extension
   • New due date: April 15
   • No penalty
3. Available assistance (depending on your situation):
   • LIHEAP (Low Income Home Energy Assistance)
   • State energy assistance programs
   • Utility hardship programs

What won't happen:

• No disconnection for at least 60 days
• No disconnection at all if you're in declared hardship
• No additional fees if we find a solution now

My suggestion: Set up the 3-month payment plan. Does that work for you?

I can also check if you're eligible for assistance programs."

Impact: Collection rate +15%, satisfaction of struggling customers +40%.

5. Guided Plan Change

The problem: "Am I on the right plan?"

The RAG solution:

Customer: "I'm on standard rate, is that good for me?"

Assistant: "Great question! Let me analyze your consumption to see if another plan would be more advantageous:

Your consumption (last 12 months):

• Total: 9,200 kWh
• Night (10pm-6am): 3,100 kWh (34%)
• Day: 6,100 kWh (66%)

Plan comparison:

Plan	Est. Annual Cost	Savings
Standard (current)	$1,740	-
Time-of-Use	$1,650	-$90
Variable Rate	$1,520	-$220

My analysis:

• Time-of-Use: Good for you
  • 34% nighttime consumption is enough
  • Guaranteed savings without changing habits
• Variable Rate: More economical BUT
  • Requires adapting usage during peak pricing
  • Some days electricity is very expensive
  • With electric heating: risky

My recommendation: Switch to Time-of-Use

• Realistic savings: $90/year
• No risk, no constraints

Should I start the switch? It's free and effective in 10 days."

Impact: Switch rate to optimized plans +50%.

6. Support During Rate Increases

The problem: Crisis communication during price increases

The RAG solution:

Customer: "I saw prices are going up again, how much more will it cost me?"

Assistant: "I understand your concern. Here's what the February 2026 increase means for you:

Your situation:

• Annual consumption: 9,200 kWh
• 2025 spending: $1,605

Impact of increase (+8.6%):

• New estimated spending: $1,743/year
• Increase: +$138/year, or +$11.50/month

What's increasing:

• Price per kWh: +12% (energy cost on markets)
• Taxes: Stable
• Delivery charges: +3%

What you can do:

1. Optimize your plan (already analyzed: $90 savings possible)
2. Reduce consumption 10%: -$160/year
   • I can send you a personalized guide
3. Check LIHEAP eligibility: Up to $500 assistance

In summary: Even with the increase, we can limit impact to zero with some adjustments.

Where would you like to start?"

Impact: Call volume during increases -40%, satisfaction preserved.
