Built by people who lived
the billing week.
Before Gridline was a company, it was a frustration. The manual processes. The utility formats that change without warning. The billing weeks that ate entire teams.
We built Gridline because we lived the problem first.
What we've built into the model
Years of operational knowledge, not just document parsing
Bill structures we handle
- Net metering statements
- Community solar credit statements
- Virtual net metering allocations
- Consolidated utility bills
- Time-of-use rate applications
Edge cases we've catalogued
- Mid-cycle rate changes
- Retroactive credit adjustments
- Subscriber moves and transfers
- Partial-month allocations
- Multi-meter subscribers
- Low-income program variations
What you don't have to do
- Copy-paste from utility PDFs
- Maintain spreadsheet formulas
- Manually create each invoice
- Hope you caught all the errors
- Spend days reconciling credits
Our journey
From frustration to automation
Gridline founded
Started from firsthand experience with community solar billing pain.
First billing automation
Deployed initial system. Started cataloguing utility formats.
Scaled to multiple programs
MA SMART, MN Community Solar Garden, and more.
Model development begins
Started training domain-specific extraction models.
Platform milestone
90%+ straight-through rate achieved.
Full platform launch
Billing cycles in minutes, not days. Full audit trail.
Today
20+ projects across multiple state programs.
Why automation works now
Operators have been doing manual billing for years. What changed?
AI got good enough
Modern AI can actually extract structured data from messy utility bills—if you know how to validate and constrain it.
We have the edge cases catalogued
Years of operational data means we've seen the variations that break naive automation.
The cost of errors is too high
As portfolios grow, manual billing doesn't scale. A 2% error rate on 10,000 subscribers is 200 problems per cycle.
How we build
Principles that guide every line of code
Operator-First
We build for the person who runs billing every month. Their workflow is our spec.
Traceable by Default
Every step logged. Every artifact versioned. Every decision auditable.
Automation with Control
Automate the repetitive. Flag the exceptions. Keep humans in the loop.
Ship Fast, Iterate
Real software solving real problems. No vaporware. No roadmap theater.
Who's building this
Mike
Founder
Building Gridline to solve the operational pain points that slow down clean energy deployment. Previously worked on energy project finance, grid resilience modeling, and document automation.
The biggest impact we could have wasn't in education or research — it was in solving the operational pain points that slow down clean energy deployment.
If you're an operator spending days on billing every month, I'd love to hear about your workflow.
The Gridline team is focused on automating bills information extraction with 100% accuracy
Our Legacy Work
From 2017-2024, we maintained an educational platform serving thousands of energy professionals. Explore our benefit reports, previous projects, and how we evolved.
