What Terrenus Energy does
Terrenus Energy is a Singapore-based renewable energy solutions provider founded in 2016 that designs, develops, finances, installs, and operates solar photovoltaic systems for commercial, industrial, and government customers across Singapore. The company operates two core business models: a Power Purchase Agreement (PPA) under which Terrenus funds, owns, and maintains the system on the customer's site at zero upfront cost, and the customer purchases generated electricity at a 30–50% discount to Singapore Power's (SP) tariff under fixed- or floating-rate structures running 20–25 years; and a Roof Leasing model in which building owners license unused rooftop space to Terrenus for a fixed monthly rental, with Terrenus retaining operational responsibility. Project execution is delivered through a dedicated Business Development Department and direct enterprise/government sales, supported by referral channels including JTC Corporation and partner networks.
The company's technology stack centres on solar PV but extends into a portfolio of proprietary innovations deployed on Singapore projects: smart electrical power meters that track energy consumption and performance of common services (e.g., lifts) across HDB blocks; a mobile substation (deployed at SolarLand 2) that containerises the substation unit to cut deployment time by up to 50%; micro-wind turbines tuned for Singapore's low-wind environment at SolarLand 1 Extension; hydropanels at Jurong Island; fence-integrated solar panels; and agrivoltaics co-location. Flagship installations include SolarLand 1 (Singapore's first grid-connected solar farm, 2019), SolarLand 2 (the country's largest ground-mounted solar farm, 11.6 hectares, 19.2 MWp), the 70 MWp SolarNova Phase 6 HDB/EDB project (1,198 blocks, 57 government sites), and SolarRoof 3 under JTC. The portfolio has scaled to 300+ MWp of installed capacity following a SGD 300 million green-loan facility arranged by a DBS-led five-bank consortium in May 2024.
Terrenus serves a mix of government counterparties (HDB, EDB, JTC, town councils) and enterprise clients (Meta/Facebook, CapitaLand, Sentosa Development Corporation, Singtel, StarHub, Dril-Quip, PEC, Kimly, Innovex, CWT, JCU, SIT), with secondary case-by-case residential interest. Operations are exclusively Singapore-based; the company holds ISO 9001, 14001, 45001, and 27001 certifications, and is led by CEO Charles Wong. Revenue is generated almost entirely through long-tenor PPAs and roof-licence rentals under 20–25 year contracts, with no public revenue disclosure available.

Revenue model
- Power Purchase Agreement (PPA) — Fixed Rate: Terrenus installs, owns, and operates the solar PV system. Customers purchase the electricity generated at an agreed fixed rate per kWh over the PPA term (typically 20–25 years). The fixed rate provides financial predictability and is set below prevailing SP tariff rates, offering 30–50% savings. Terrenus retains system ownership and all operational responsibilities throughout the contract.
- Power Purchase Agreement (PPA) — Floating Rate: A percentage discount off the prevailing SP tariff rate for the solar electricity consumed, offering variable but still discounted pricing relative to grid rates.
- Roof Leasing: Building owners lease unused rooftop space to Terrenus for monthly rental income. Terrenus installs and operates the solar PV system. No electricity supply agreement is involved — revenue is purely rental income from the roof licence. This model suits buildings with configuration constraints that make PPA arrangements unfeasible.
Pricing tiers

| Subscription | Monthly | PPA — Fixed Rate: Locked-in rate per kWh for the full contract term |
| Subscription | Monthly | PPA — Floating Rate: Variable discount off prevailing SP tariff |
| Other | Monthly | Roof Leasing: Fixed monthly rental fee for roof space licence |

Terrenus Energy product offering
Product offeringCore offering
Terrenus Energy funds, designs, installs, owns, and operates solar photovoltaic (PV) systems on rooftops and ground-mounted sites across Singapore under zero-CAPEX business models. Customers purchase solar electricity at 30–50% below prevailing grid tariffs under long-term Power Purchase Agreements (PPAs) of 20–25 years, or monetise unused rooftop space through a fixed roof leasing arrangement with Terrenus absorbing all capital and operational costs.
Product overview
Terrenus Energy offers two primary business models for solar energy adoption: the Power Purchase Agreement (PPA) and Roof Leasing Model. Under the PPA, the company funds, installs, owns, and maintains solar PV systems at customer premises with zero upfront cost, while customers purchase electricity at 30-50% below market rates with fixed pricing over 20-25 year terms. The Roof Leasing Model enables building owners to monetize unused rooftop space for passive rental income. The company's portfolio includes large-scale projects such as SolarLand 1 Extension, SolarLand 2 (Singapore's largest ground-mounted solar farm), SolarNova 6 (1,198 HDB blocks), and SolarRoof 3. Proprietary innovations include smart electrical power meters, mobile substations, fence-integrated solar panels, micro-wind turbines, hydropanels, and agrivoltaics solutions. The company serves commercial and industrial clients including Sentosa, Singtel, CapitaLand, PEC Ltd, and JTC Corporation.

Terrenus Energy competitors and assessment
Company assessmentDirect peers
- Sunrun: US-listed leader in residential solar leases and PPAs; closely comparable zero-CAPEX own/operate model with long-term contracts and customer-funded growth, albeit residential-skewed and US-geographic.
- Tesla Energy (formerly SolarCity): Owns/operates distributed solar assets and offers solar subscription-style contracts globally. Comparable own/operate solar business model, with broader geographic footprint.
- Origis Energy: US-based solar developer focused on commercial and industrial PPAs and utility-scale solar development. Direct comparable in model (own/operate, C&I PPA, multi-decade contracts) and customer segments.
- Sunseap Group: Singapore-based solar developer (now under Engie) that has participated in government solar programmes and built distributed and utility-scale solar across the city-state. Direct competitor for SolarNova, SolarLand and commercial solar mandates.
- Cleantech Solar: Singapore-headquartered solar developer offering zero-capex solar PPA solutions to commercial and industrial clients across Asia. Closest peer in target market, business model (PPAs/own-and-operate), and geography.
- SunPower Corporation: US-headquartered solar PV and energy services company with a commercial focus and PPA/lease offerings. Similar business model of selling solar electricity to C&I customers via long-term contracts.
Broad incumbents
- Engie: Global energy major with significant distributed solar and renewable operations in Singapore and APAC, including via its ownership of Sunseap. Overlaps on government solar tenders and enterprise PPA offerings.
- Sembcorp Industries: Singapore-listed industrial conglomerate with major solar and renewable energy operations across Asia. Competes for government solar programmes and large enterprise PPAs as part of a diversified clean energy portfolio.
- EDP Renováveis: Global renewable independent power producer with a growing APAC and utility-scale solar footprint. Competes for large-scale solar PPAs and government tenders, with overlaps in technology and customer segments.
Regional players
- Greenko Group: India's largest renewable independent power producer with a significant solar IPP portfolio. Comparable asset-heavy, long-term-contract renewable IPP business, but operating primarily in a different geography (India rather than Singapore).
