Marine Energy Certificates (MECs)

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

Fund tidal, estuary, and river energy today. Redeem as bill credits when we start generating.

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: When our arrays go live, your MECs are 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 sell power at wholesale and work with utility partners to apply Marine Energy kWh credits to your bill, topping up the difference.

4) Verify anytime

Look up any certificate by GUID. See allocation, redemption status, and generation batches. No double counting.

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: redeem to your own bill or allocate to a school, clinic, or community project.

Protecting marine life

We work to strict environmental standards: seasonal surveys, real-time monitoring, adaptive operations, and transparent reporting. Arrays are sited and designed to safeguard marine mammals and habitats.

Trust & verification

  • GUID for every certificate with a public verification page.
  • Independent audit trail for issuance, allocation, and redemption events.
  • 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 begins after commercial operation of our arrays. Each MEC includes a vintage window during which it can be applied as bill credits.

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.
