The energy storage industry is rapidly moving from standalone battery systems towards innovative service-based models that offer greater flexibility and value to customers. Known as Energy Storage as a Service (ESaaS), these new business models align the interests of storage developers, utilities and energy consumers by packaging storage capabilities into tailored service offerings.

Subscription-Based Services Unlock Storage Potential

Rather than purchasing battery infrastructure outright, more customers are subscribing to energy storage services on an ongoing contractual basis. This lowers upfront investment barriers and passes long-term value and risk management to storage experts. Utilities in particular benefit from avoiding large capital expenditures while gaining dispatchable capacity and grid services from third-party providers. Customers pay only for the storage value delivered through the contract period, freeing them from technology ownership concerns. With no hardware to maintain, operate or upgrade, subscription models reduce operational complexities.

Optimized for Revenue Streams Beyond Energy Shifting

Traditionally, Energy Storage as a Service was mainly used for time-shifting renewable generation or lowering peak demand charges. But ESaaS unlocks the potential to capture multiple synergistic revenue streams. Providers can stack value streams by offering grid services like frequency regulation in addition to retail energy cost optimization.

Leveraging artificial intelligence and advanced controls, storage assets are optimized 24/7 for maximum financial returns across both wholesale and retail markets. This multi-purpose flexibility was not possible with standalone battery ownership models.
