With a subscription or pay-per-use model, EaaS allows organizations to access advanced energy technologies such as solar, battery storage, and smart energy management without the burden of owning or maintaining the infrastructure.

EaaS provides managed energy solutions that let businesses focus on their core operations while experts handle energy generation, efficiency upgrades, and monitoring. This model is transforming how Indian companies manage energy consumption and achieve sustainability targets.

What is Energy as a Service (EaaS)?

Energy as a Service, commonly known as EaaS, is a business model where companies provide end-to-end energy solutions on a subscription or pay-per-use basis. Instead of owning energy infrastructure, businesses access services such as renewable energy generation, energy efficiency upgrades, energy storage, and monitoring tools. The service provider handles all aspects of energy management, including installation, operation, and maintenance.

This model allows organizations to reduce upfront capital expenditures, lower operational risks, and benefit from the latest energy technologies without managing complex energy systems themselves. In India, where energy costs are a significant operational burden for businesses, EaaS offers a practical approach to achieving cost savings, improving efficiency, and meeting sustainability goals.

How EaaS functions: A step-by-step overview

Energy as a Service works by shifting the responsibility of energy management from the business to a dedicated service provider. Instead of purchasing and maintaining energy infrastructure, companies pay for outcomes such as energy efficiency improvements, renewable energy generation, or predictable energy supply. This allows businesses to focus on core operations while leveraging modern energy technologies.

Key components of how EaaS works include:

 

  • Subscription or pay-per-use energy solutions:  Instead of purchasing or maintaining their own energy infrastructure, businesses using the EaaS model pay for outcomes like improved energy efficiency, renewable energy generation, or a consistent and predictable energy supply, rather than the physical assets themselves.
  • Provider handles the infrastructure: The EaaS provider designs, installs, operates, and maintains energy systems such as solar panels, battery storage, and energy-efficient lighting.

Frequently asked questions

The frequently asked questions section is a reliable source for unlocking answers to some of the most crucial inquiries. Please refer to this section for any queries you may have.

 

An ESCO (Energy Service Company) is a specialized organization that provides energy-efficiency solutions and guarantees energy savings for clients. ESCOs design, implement, and manage energy-saving projects, such as lighting upgrades or HVAC optimization, and are typically paid based on the actual savings achieved.

 

Energy SaaS (Software as a Service) refers to cloud-based platforms that provide energy monitoring, analytics, forecasting, and optimization tools. Instead of installing software or hardware, businesses subscribe to these digital energy services to track consumption, identify wastage, and improve efficiency through real-time insights.

 

The ESCO model is a performance-based approach where the ESCO develops and implements energy-efficiency projects, and its payment is tied to the energy savings generated. This means the ESCO carries the performance risk like if the project doesn’t deliver the promised savings, the ESCO earns less. It helps clients improve efficiency without upfront investment.

 

While Energy as a Service (EaaS) offers flexibility, cost savings, and access to advanced technologies, it also comes with certain limitations that businesses should consider:

Long-term contractual commitments:

EaaS typically involves multi-year agreements to justify infrastructure investments. This can limit flexibility if a business’s energy needs change or if it wants to shift providers later.

Dependence on the service provider:

Since the provider owns, operates, and maintains the energy systems, the business becomes highly dependent on their performance, reliability, and responsiveness. A weaker provider can impact energy quality and operational uptime.

Limited customization for complex facilities:

While EaaS works well for common industrial, commercial, or retail setups, highly specialized or energy-intensive operations may require custom solutions that some providers may not offer.

Data privacy and cybersecurity concerns:

EaaS solutions rely heavily on digital monitoring, IoT devices, and real-time data analytics. Sharing operational data with an external partner can raise security or compliance concerns for certain businesses, especially in sectors like BFSI or data centers.

Possible cost escalation clauses:

Depending on the contract structure, some EaaS models may include periodic price revisions due to inflation, technology upgrades, or regulatory changes, which businesses need to factor in.
