Shape the standard while it is still being written.

The class definitions and requirements your market will certify against are being written now, in the working groups. Becoming a member allows you to shape them.

What the Membership means

A vote while the standard is still open

The class definitions your market will certify against are being written now, in the working groups. Full Members vote; Observers are heard. Join early and you help write the specification you will later certify to, instead of inheriting one others wrote.

Position as procurement shifts

Standards-based procurement is the direction of travel in the UK, the EU, Australia, and California. Membership keeps you close as that picture forms.

A return sized to your integration load

The payoff comes from certifying; membership makes sure the class you certify against is one you helped set. What it is worth differs by seat: a wider tariff base for a retailer, a deferred substation reinforcement for a network operator, retired per-brand integrations for a platform.

Mercury Membership & Mercury Mark certification

Certification is the technical work that earns a device the Mercury Mark - proof that it responds, reports, and handles issues to a defined class. A company can certify its devices without becoming a member.

Membership is the decision to fund and steer the certification itself. Each member votes on the roadmap, certification, and the Mercury board. Want to ensure interoperability of your device and reduce integration burden? Certification alone may be enough.

Want a say in what the grid interoperability of devices looks like in 3 years? Join. Many do both, and start certifying as members so they help set the definitions they will later certify to.

Full Member

The seat for a company that wants to shape the standard. Full Members lead working groups, vote on the roadmap, and can stand for the Board. If where the standard goes affects your product plans or your market, this is the tier that gives you a hand on it.

Full Members lead and vote.

Observer

The lower-commitment seat. Observers attend and contribute to working groups, without a vote or Board eligibility. It suits an organisation that wants early sight of the roadmap while it decides, and it is the standard route for regulators and other organisations that must engage without endorsing.

Observers attend and contribute.

Who should join

Join If

your product or platform has to work with utilities or flexibility markets, and today that link is rebuilt for each partner you add;

you are adding device brands, entering new markets, or launching flexibility products, so integration cost compounds as you grow;

you want a say in the class definitions your market will certify against;

you are a network operator weighing certified flexibility against reinforcement, or a regulator or association looking to engage with, or recommend, a vendor-neutral standard.

Wait If

your product does not need to interact with utility networks or flexibility platforms;

you treat a proprietary integration as a competitive moat, which the standard runs against by design;

you are pre-product or pre-revenue, with no shipping device to certify;

you are mid-acquisition or in a review that will defer any new standards commitment.

How to join

1.

Start a conversation. A short call to help our team understand where you sit between devices, platforms, and utilities, what you need to connect, and whether membership, certification, or observer engagement fits.

2.

Choose your class and fee tier. Full or Observer, set by company revenue.

3.

Sign the membership agreement.

4.

Set a start date. Membership runs annually from the date you name.

Frequently Asked Questions

What does membership cost?

Annual fees scale with company revenue, from $10,000 Full or $5,000 Observer under $100 million to $50,000 Full or $30,000 Observer over $1 billion. Nonprofit, academic, and government applicants pay the lowest tier, with a fee waiver possible at the Board's discretion.

Can we certify a device without joining?

Yes. Certification and membership are separate decisions. Certification is the technical work that earns a device the Mercury Mark, and you can do it without becoming a member. A company that only wants to comply can certify alone; a company that wants to shape the standard joins.

What is the difference between Full and Observer membership?

Both attend meetings and events, access the member portal, and contribute to working groups. Full Members also lead working groups, vote on the roadmap, and are eligible for the Board and leadership roles. Observers do not vote and are not Board-eligible. Full is the tier for shaping the standard; Observer is the lower-commitment seat, and the standard route for regulators.

Can regulators or nonprofits get the fee waived?

Yes. Nonprofit, academic, and government applicants pay the lowest tier, and the Board can waive the fee at its discretion. For regulators, the waiver-supported Observer tier is the usual route: observer status is engagement without endorsement, and reciprocal - Mercury observes you, you observe Mercury.

How long does it take to join?

Once you have chosen a class and tier, membership starts from a date you name. The pace is usually set by your own legal review, and the agreement is written to be reviewed without surprises. Certification work, if you are pursuing it, can run in parallel.

Can we start as an Observer and move to Full later?

Yes. Observer is a common first step: early sight of the roadmap and a way to contribute while you watch the standard mature, then a move to Full when you want the vote and a Board seat.
