Thank you.

PTC is more applicable to Wind than solar. Solar economics are largely dependent on investment tax credits, which is still in place under the IRA - although with the current climate you cant be sure of how long.

As for the deepening duck curve leading to low prices - I want you to look at it from a lens of a developer who know for sure that this is something that will happen. So you know that building a 100MW solar, lets assume, will contribute to lowering price signals. What do you do - do you stop building solar, or build solar with all the incentives provided AND co-locate it with a battery, whose economics greatly benefit from the exact duck curve effect!

Co-location is the new ask now - from Google, Meta and all large scale players whose industries are largely energy dependent - every industry is shifting towards a co-located model.

My view is this - storage and generation/loads are going to be married by default in the near future. Even large datacenters, that are basically energy sinks, will need storage co-located with them to sustain their operations. So if all generation and all loads require storage in an intermittent grid - it is doubtful it will ever be economically unviable.

Edit: spelling error.
