Is Gridcog for consultants?

Gridcog lists consultants working on commercial and industrial sites among its users, next to utility-scale developers, e-mobility businesses and energy majors. Its plans are counted in active sites a month and energy markets.

Does Zorowatt model energy markets?

Only as far as one site's bill goes: a dynamic supply contract from a day-ahead price file you upload, and arbitrage where the spread beats the losses. Zorowatt does not model front-of-meter projects, ancillary services or trading.
