Grid Interconnection Consulting
Utility interconnection queues, not solar economics, are now the primary reason small commercial solar, storage and industrial-load projects stall for years or die outright. A consultant who knows a handful of utility territories' tariffs, study processes and application portals cold can charge meaningfully for de-risking and speeding a process that otherwise blindsides developers.
Strong structural demand -- LBNL-documented multi-year queue backlogs and FERC Order 2023 reform create genuine confusion small developers will pay to navigate -- and the competitive field is thin relative to the demand signal, since most interconnection expertise sits inside utilities, large EPCs, or big-project law/engineering firms that don't chase small commercial deals. The ceiling is schedule-driven consulting labor, not a product, so scalability depends on building a team or productizing the feasibility-screen offering.
Lawrence Berkeley National Lab's interconnection queue tracking shows typical wait times from initial request to commercial operation now running multiple years in many regions, with far more capacity in queues than actually gets built. FERC Order 2023, finalized to speed up and clarify interconnection study processes (first-ready-first-served clustering, tighter study deadlines, penalties for utility delays), is reshaping the rules utilities operate under -- but implementation timelines and specifics vary a lot by utility, which is exactly the kind of complexity a small developer without in-house regulatory staff will pay a specialist to translate. Commercial-scale solar interconnection costs run roughly $500/kW and storage roughly $440/kW on average, so a project sponsor spending hundreds of thousands on interconnection has real incentive to pay a consultant a small fraction of that to avoid a multi-year stall or a rejected application.
Fairly flat; slight uptick tied to developers pushing to file before utility tariff or queue-cluster deadlines, which vary by utility rather than by calendar season.
Suits you if
- ✓You have solar/storage engineering, utility regulatory, or project-development experience
- ✓You're comfortable with schedule-controllable B2B consulting engagements rather than transactional sales
- ✓You can partner with or become a licensed PE for stamped interconnection submittals
- ✓You want a high-margin service business that doesn't require inventory or manufacturing
Skip it if
- ✕You don't have or can't access utility interconnection/regulatory domain expertise
- ✕You want a fully passive or productized business -- this is expertise-driven advisory work
- ✕You're not willing to specialize deeply in a small number of utility territories' processes
- ✕You need fast transactional revenue -- project cycles and utility study timelines are inherently slow
| Units | Revenue range | Note |
|---|---|---|
| 5 | $30,000–$45,000 | Part-time viable, mostly feasibility screens |
| 15 | $75,000–$110,000 | Full-time solo consultant at steady mix of screens and full applications |
| 30 | $130,000–$180,000 | Requires a second consultant or associate to sustain |
Skills: Utility interconnection application and tariff literacy, one-line diagram review, project management across multi-month utility study timelines, and client-facing consulting/advocacy skills to manage expectations through a genuinely bureaucratic process.
