Maybe I’m not picturing it correctly but wouldn’t a negative price mean more money in your wallet? Or are you saying that the set price is less than it costs to produce the energy on your side?
Conversely, at such times you can get paid to consume electricity.
They've added some grid scale batteries - https://www.asce.org/publications-and-news/civil-engineering...
> Situated on 8 acres of industrial land, the Kapolei Energy Storage project comprises 158 Tesla Megapack 2 XL lithium iron phosphate batteries, which are about the size of a shipping container. All told, the KES project provides 185 MW of total rated power capacity, or the largest possible instantaneous discharge, and 565 MWh of energy capacity, or the maximum amount of stored energy.
> The system can meet 17% of Oahu’s electricity demand for three hours at peak load or six hours at half load, Brandon Keefe, the executive chair of Plus Power — the company that developed the project — told USA Today. Plus Power “develops, owns, and operates standalone battery energy storage systems that provide capacity, energy, and ancillary services, enabling the rapid integration of renewable generation resources,” according to the company’s Jan. 11 news release announcing the start of operations at its KES facility.

The amount of power rooftop solar in Hawaii is allowed to export to the grid is regulated.
> Customers enrolled in NEM Plus Limited Export are required to install a control device at the utility meter to limit the combined export capacity of the existing and additional generation to the capacity of the original NEM system. The battery must be programmed to 'load-following' mode so as not to export to the grid -- except when providing exports for grid services.
