Canadian Solar Energy Storage in Gansu Power Spot Market Practice

This document details Canadian Solar Group's practice of energy storage power stations participating in the Gansu power spot market, drawing lessons from overseas models. It outlines the revenue model for Gansu energy storage stations, including electricity spot market, ancillary services market (frequency peak regulation), and capacity electricity price. The spot market shows significant price differences between peak and off-peak hours, with evening peaks averaging over 340 yuan/MWh and noon photovoltaic troughs under 100 yuan/MWh. The ancillary services market includes peak shaving and frequency modulation, with substantial cumulative compensation. Capacity electricity price is set at 330 yuan/kilowatt/year for a two-year trial, encouraging long-duration storage. The document compares traditional domestic investment models with overseas compound interest income models, emphasizing full life-cycle value through participation in multiple markets and long-term service agreements. Canadian Solar positions itself as an integrator, EPC contractor, and O&M service provider, offering end-to-end solutions from planning to service. Case studies include domestic projects in Gansu and Jiangsu, and overseas projects in California and Arizona.
