Certification Capacity Catches Up With Policy: Codibly Named SunSpec Authorized Test Lab for IEEE 2030.5
By Zach Woogen
The SunSpec Alliance has designated Codibly an Authorized Test Lab for Institute of Electrical and Electronics Engineers (IEEE) 2030.5, including the Common Smart Inverter Profile (CSIP). The designation, announced in March 2026, expands the network of accredited labs able to test and certify distributed energy resource (DER) products against the protocol that increasingly underpins state-level vehicle-grid integration (VGI) policy.
For Vehicle-Grid Integration Council (VGIC) members tracking the market through 2026, this marks a real shift in a constraint that has been quietly tightening: the gap between what regulators are now requiring and the certification capacity available to deliver against it.
A protocol pulled into the regulatory frame
Over the past 18 months, IEEE 2030.5 has moved toward a key interoperability layer in several jurisdictions VGIC has covered closely, including:
California's Rule 21 has anchored 2030.5/CSIP for smart inverter communications for years and remains the reference point for most West Coast deployments.
Maryland's Vehicle-to-Grid (V2G) interconnection framework, finalized in mid-2025, leans on 2030.5 as a pathway for EV-as-DER participation.
New York's Value of Distributed Energy Resources (VDER) tariff continues to recognize 2030.5-based telemetry as a compliant route for value-stack participation.
Policy often codifies a protocol expectation faster than the surrounding ecosystem — testing labs, integrator bench depth, OEM firmware pipelines — has scaled to meet it. For OEMs, DERMS vendors, and utility procurement teams, "certification timeline" has shifted from a back-office detail to a real schedule risk.
What additional lab capacity actually changes
A new accredited test lab does not, on its own, accelerate any single project. What it does is shorten queues, add geographic and time-zone coverage, and — when the lab also runs adjacent protocol benches — reduce the cost of testing products that need to clear more than one certification at a time.
Codibly's profile fits that last category. The company is also an Official Implementation Partner of the OpenADR Alliance and operates testing capability across OpenADR 2.0b, OpenADR 3.0, SunSpec Modbus, and now IEEE 2030.5/CSIP. For multi-protocol products — and most modern DERMS, smart inverter, and bidirectional charger stacks fall into that category — running compliance work against several specs in one engagement is a meaningful cycle-time difference.
The geographic note is also worth flagging. Codibly is EU-headquartered with active US delivery, which puts a 2030.5 testing seat closer to a portion of the V2G product pipeline that has been building outside North America and shipping into US programs. Codibly has been supporting Southern California Edison (SCE) Stability Improvement with Distributed Energy Resources (SIDER) program and Pacific Gas and Electric Company (PG&E) Flex Connect program vendors (aggregators) as recent examples of IEEE 2030.5 certification and implementation aimed at scaling real world impacts on grid stability from EVs.
For VGIC members and partners, the practical read is that one of the recurring constraints on member product launches in 2026 — securing a 2030.5 certification slot on a workable timeline — gets incrementally less binding.
Going deeper on operating DERs at scale
Certification is the entry ticket; what happens after products hit the field is its own conversation. On May 27, 2026, Codibly and Enode are co-hosting a webinar — Operating Distributed Energy at Scale: What It Takes to Turn DERs into Consumer Flexibility — covering the connectivity layer across EVs, batteries, and heat pumps; program-design and proposition trade-offs; and EU/US market-structure differences for consumer flexibility. VGIC members working on V2G program rollouts will likely find the multi-asset framing relevant. Registration is open via Codibly's LinkedIn page.
Looking ahead
Certification capacity is necessary but not sufficient. The next inflection — and arguably the harder one — is interoperability under live grid conditions: how certified products from different vendors actually behave together once they are aggregated into managed-charging programs, virtual power plants (VPPs), and bidirectional charging deployments. Lab benches catch protocol conformance. Field interoperability is where 2026 deployments will be tested in earnest. Expanding the certification base is part of getting there; it is not the whole of it.
