Storage PPAs and traditional PPAs differ primarily in their focus rather than their contract duration. Both types of PPAs typically span a duration of 10 to 25 years, similar to other long-term agreements in the renewable energy sector.
However, the main difference lies in the services provided:
- Traditional PPAs focus on the purchase of generated electricity from sources like solar or wind. They are contracts between a developer and a buyer (such as a utility or corporate entity) where the buyer agrees to purchase electricity at a predetermined price over a specified period.
- Storage PPAs specifically address the provision of storage services. These include energy arbitrage, peak shaving, frequency regulation, and backup power, which are essential for stabilizing the grid and managing the intermittency of renewable sources.
In terms of contract duration alone, there is no inherent difference between storage and traditional PPAs; both can range from 10 to 25 years. The distinction is more about the nature of the services provided and how they are integrated into the energy market.
