Grid 2.0 Standards Documentation

Pages

1. OverviewWhat the Grid 2 overlay plane is, who implements or comments on it, the three-protocol stack, and the first docs routes after RFC #1.
2. How to read the specsStatus headers, RFC 2119 keywords, living files versus immutable RFCs, independent 26.x lines, and what Draft seeking input still leaves open.
3. Minimum viable domainSmallest Grid 2 domain: one host utility plus one flexible load, transmission-owner constraint provisioning, and the connect-and-manage on-ramp.
4. Overlay and Grid 1Overlay membership without a perimeter, NERC/FERC/TSO non-interference, coordination without prices, and v26.0 energy-in-the-interval scope.
5. One-minute windowOne-minute interval clock between ~5-minute market dispatch and sub-second ancillaries, commit-before-open, and the Grid 1-prevails conflict rule.
6. Allocation domainsNested constraint domains, transmission-owner authority, voluntary membership by spec compliance, and commercial terms that stay outside the protocol.
7. Service classesDESP classes A, B, and C above Grid 1 Firm, curtailment order C then B then A, Firm/Semi-Firm/Flex aliases, and per-interval reclassification.
8. Failsafe modelNo-surprises fallbacks per element, interval-only commitments, pool ramp limits, and fallback that is locally determinable without a remote peer.
9. FederationAllocator announce-and-listen, nested local-to-regional domains, missing-announcement conservative clearing, and partition that does not trip unrelated members.
10. Run Phase 0 shadow modePhase 0 dry-run: exchange and track commitments, execute only the Grid 1 baseline, then graduate to Phase 1 local integration and Phase 2 federation.
11. Map workloads to classesInformative Flex 0–3 and ERCOT CLR/PCLR mappings onto DESP A/B/C, plus what the Allocator never sees inside a facility.
12. Provision constraint inputsRequired Grid 1 constraint set, optional DLR and distribution-factor inputs, input digests, and the rule that peer announcements must not relax local limits.
13. Comment, review, and file errataDiscussions versus Issues versus PRs, RFC #1 errata label, two-editor review, RFC 2119 and compatibility statements, and decision-log recording.
14. G2P referenceElement identity, four message families, one-minute timing, authenticated descriptors and commitments, stale-commitment faults, and unspecified wire format.
15. GCAP referenceClearing inputs, headroom-then-buffers-then-tiered-curtailment, per-class commit outputs, identical-input determinism, and pool and ramp-safety bounds.
16. DESP referenceClass table and semantics, mandatory C-B-A curtailment order, domain class-policy limits, and open naming, extensibility, and SLA items.
17. Use MemberPer-class consume positions, commit-% listen, edge workload mapping, self-dispatch and telemetry MUSTS, ramp limits, and firm-limit fallback.
18. Buffer MemberSigned charge and discharge offers, committed dispatch before any load curtailment, verified self-dispatch, SoC open items, and standalone Grid 1 schedule fallback.
19. Source MemberSupply offers over a forward vector, committed take, forecast-error open items, v26.0 single-class supply, and Grid 1 interconnection fallback.
20. AllocatorNo-discretion deterministic clearing, constraint-authority inputs, federation announcements, withhold-on-stale, and whole-pool ramp sizing.
21. Document lifecycleDraft to Proposed to Stable to RFC, YY.N protocol versions, required compatibility statements, and the GOVERNANCE.md decision log.
22. ContributingOpen individual participation, comment-cycle steps, RFC 2119 and one-sentence-per-line conventions, and implementation reports from Phase 0 onward.
23. Governance and licensesEditor, contributor, and Task Force roles; rough consensus; CC BY 4.0 spec text and Apache-2.0 code; trademarks; and Grid 1 regulator relationship.
