NOTE
Merchant economics now clear in three markets
Unsubsidised four-hour storage clears in three US markets on merchant economics alone. That changes who the buyer is and how projects are financed.
It also changes the financing. Merchant projects can be underwritten on market revenue curves, which brings in a different and much larger pool of capital than subsidy-dependent projects can access.
Merchant clearing means the project earns its return from market revenue without a support mechanism. Once that threshold is crossed the buyer set widens from programme-driven developers to anyone with a balance sheet and a grid position.
The caveat is that clearing at current spreads is not the same as clearing through a cycle. Spreads compress as storage penetration rises, and the projects being underwritten today are being underwritten on today's spreads.
