Marine Energy Certificates (MECs)

Buy future clean electricity in the units you know — kWh.

Fund tidal, estuary, and river energy today. Subject to commissioning and utility partnerships, MECs can be redeemed as bill credits once generation begins.

Why choose Marine Energy Certificates

  • Simple & familiar: MECs are denominated in kWh — the same unit on your energy bill.
  • Real infrastructure: Your purchase helps build predictable, renewable power from our waters.
  • Future redemption: Subject to commissioning and participating utility agreements, MECs may be applied to your bill as Marine Energy kWh.
  • Protecting nature: We design around marine mammals and habitats, with independent monitoring and open data.

How MECs work

1) Buy kWh today

Purchase MECs at today’s retail value (e.g. 100, 500, or 1,000 kWh). Each certificate receives a unique GUID and appears in your dashboard.

2) We build & generate

Your support funds development of marine energy arrays across rivers, estuaries, and coastal sites. Output is predictable and trackable.

3) Redeem on your bill

Once operating, we intend to sell power at wholesale and work with participating utility partners to enable application of Marine Energy kWh credits to eligible customer bills.

4) Verify anytime

Look up any certificate by GUID. See allocation, redemption status, and generation batches. Designed to prevent double allocation of generation batches.

What you get today

  • Certificate wallet: clear record of your MECs (GUIDs, kWh, vintage window).
  • Progress updates: milestones, live tidal forecasts, and site news.
  • Choice of beneficiary: We intend to work with participating utility partners to apply Marine Energy kWh credits to customer bills once operational.

Protecting marine life

Projects are developed in line with environmental assessment requirements and best-practice marine monitoring. Seasonal surveys, real-time monitoring, and adaptive operations are used to safeguard marine mammals and habitats.

Transparency & governance

  • GUID for every certificate with a public verification page.
  • Structured audit trail for issuance, allocation, and redemption events, with provision for independent review.
  • No offsets or futures trading: MECs are future electricity matching, not tCO₂e credits.

Faq

Is this an investment product?

No. MECs are a pre-purchase of future electricity matching in kWh. They do not pay interest or dividends.

When can I redeem?

Redemption may begin following commercial operation of our arrays, subject to successful commissioning and participating utility agreements. Each MEC includes a vintage window during which it may be applied as bill credits in accordance with our published MEC redemption policy.

What if I switch supplier?

You can reassign your MECs to another participating utility or allocate them to a beneficiary (e.g., a local school) during your vintage window.

What happens if I don’t redeem?

Unredeemed MECs at the end of the vintage window are allocated to community energy beneficiaries according to our policy.

Note: Marine Energy Certificates represent a pre-purchase allocation of future marine electricity matching (in kWh). They are not carbon offsets, not financial securities, and not regulated investment products. Redemption is contingent upon successful project commissioning and agreements with participating utility partners. If commissioning or partnerships are delayed, redemption timelines may be adjusted in accordance with our published policy.
