At Terrenus Energy, we are committed to providing a seamless and cost-effective transition to renewable energy, empowering businesses and building owners to harness the power of solar energy with ease and confidence. Our two business models—Power Purchase Agreement and Roof Leasing—offer tailored solutions that maximise cost savings, generate revenue, and contribute to a greener future.

 

Power Purchase Agreement (PPA)

A proven and widely adopted model, PPAs are designed for businesses seeking to enjoy the benefits of solar energy without the burden of upfront costs. Under this model, Terrenus Energy handles the complete installation, maintenance, and operation of a solar energy system on your premises at no capital or operational expense to you.

The PPA structure ensures a stable and predictable electricity supply, by agreeing on a fixed rate for the electricity generated, ensuring stability and protection against market fluctuations. These financial hedges protect businesses from volatile real-world scenarios such as international conflicts, turmoil, or other significant forms of economic instability causing a surge in energy demand. By choosing a PPA with Terrenus Energy, businesses can achieve significant cost savings, with electricity prices reduced by an average of 30 to 50% compared to conventional SP tariffs.

PPAs are typically structured for a duration of 20 to 25 years, ensuring long-term financial and operational stability. By covering all capital and operational expenditures, we remove any financial risks for our clients while guaranteeing reliable and affordable clean energy for decades. At Terrenus Energy, we prioritise consistency, reliability, and affordability, delivering clean energy solutions that drive both sustainability and economic growth.

 

Roof Leasing Model

For building owners looking to monetise their unused rooftop space with zero effort, our Roof Leasing Model presents an attractive opportunity. By leasing out your unused roof space to Terrenus Energy, you enable the development of solar photovoltaic systems that contribute to Singapore’s renewable energy targets—while receiving a stable, fixed monthly rental income in return. 

Many of the rooftops on Singapore’s commercial buildings are faced with configuration and layout constraints, which impinges on the delivery of electricity and sometimes make conventional PPA arrangements unfeasible. For these buildings, roof leasing is the next viable alternative in solar generation.

Unlike a PPA, the solar leasing model does not involve any agreement on the supply of electricity. Instead, it serves as an option for building owners to unlock additional revenue streams without capital investment or operational responsibilities.

Given Singapore’s land constraints and high population density, available roof space is an invaluable asset. Maximising the use of rooftops for solar energy generation plays a crucial role in supporting the nation’s sustainability goals and reducing carbon emissions.
