Interconnection insight
Close readings of the filings that decide whether a project gets built: FERC orders, ISO tariffs and state commission rules. 5 pieces, 8,906 words, 26 primary documents — every number in them traceable to one of those documents.

ERIS vs NRIS: which interconnection service should your project request?
Neither service conveys transmission service. The difference is whether your plant gets studied — and upgraded — so it can be designated a Network Resource.

About this section
- What is this section for?
- Interconnection and transmission rules are where energy projects and large loads actually succeed or fail, and the rules live in FERC orders, ISO tariffs and state commission dockets that are rarely read outside the proceeding. Each piece here is a close reading of named documents, with every figure sourced to one of them.
- How current are these?
- Each article carries its publication date and the docket or filing date of every document it reads. Tariffs change; a piece that reads a proposed rule says so, and names the comment deadline.
- Is this legal advice?
- No. It is a reading of public documents with links to every one of them, so you can check the reading against the source.
