A solar/renewable energy PPA is a long-term agreement between your business and a private PPA provider.
A solar private power purchase agreement (PPA) helps businesses in Thailand access the sun’s boundless energy without purchasing a complete solar power system. Your company purchases electricity generated by the solar system installed at your facility at an agreed rate, rather than paying upfront for critical services and infrastructure, such as:
A private PPA in Thailand can be especially valuable for companies with high daytime electricity demand. As an experienced PPA private company, Kunini will arrange a private PPA solar arrangement, meaning we design, finance, install, own, operate, and maintain the system on your property. Your business benefits from solar electricity that’s typically priced below the applicable PEA or MEA electricity tariff, making it a game-changing strategy for energy-intensive sites, and suitable for the following:
Solar PPA in Thailand can be useful for factories, hotels, warehouses, offices, condominiums, restaurants, gyms, healthcare facilities, schools, and other commercial buildings. A private PPA solar rooftop offers a practical path to lower operating costs, improved cash flow, and superior sustainability performance.


A solar power purchase agreement is a long-term agreement between your business and a private PPA provider. Kunini (or its investment partner) funds the project and owns the solar asset for the duration of the contract. Your business then buys the system-generated power at the pre-agreed rate.
This means there’s no need for your company to invest capital upfront or manage the technical side of solar generation. Throughout the private PPA, we expertly and efficiently handle the entire process, including:
At the end of the private power purchase agreement, ownership of the solar power system will transfer to the customer in accordance with the agreed terms. Your business can then continue using the system and benefiting from solar generation for years to come.

Electricity is a major cost for many businesses in Thailand, where tariffs can be affected by factors such as:
Under these conditions, long-term energy planning can be challenging, but a commercial solar PPA in Thailand can reduce dependence on grid-supplied electricity by producing solar energy at your premises. For businesses with heavy daytime consumption, this can produce immediate savings from the very first month of operation.
The model is also effective for companies that want solar energy but prefer to preserve capital. Instead of spending large sums on their own systems, private PPA electricity rates allow businesses to maintain cash flow for:
Lower operating costs help strengthen competitiveness and drive profitability.
Once the proposal is approved and you sign a private PPA, Kunini manages the full delivery process, including:
After the system goes live, your business purchases the solar-generated electricity while continuing to supplement with grid power when needed.
The process starts with a private PPA consultation. To determine the best system size for your facility, the Kunini team will assess your location, electricity use, and project requirements, including:
Our experts will then prepare a proposal showing the following:

Every Solar PPA installed by Kunini is designed around the customer’s own electricity consumption profile. Most projects operate as behind-the-meter, self-consumption systems with Zero Export control where required by PEA or MEA. Electricity generated by the solar system is consumed directly within the customer’s facility, maximising savings while ensuring compliance with local utility requirements.
A private PPA in Thailand can provide immediate savings without upfront capital expenditure. Your business doesn’t need to purchase equipment or accept the technical risk of operating the system. Some significant advantages include:
For many organisations, solar plays a crucial role in a wider environmental strategy, and a solar PPA can also support:

Purchasing a solar system can make sense for companies with available capital that seekto own the asset from day one. However, ownership also means taking responsibility for ongoing expenses and logistical challenges, including:
The model for corporate PPA in Thailand works differently. Kunini or its investment partner funds and owns the system during the contract, while the customer buys the electricity produced. This allows the business to benefit from solar energy without diverting capital from core operations.

Private PPA for businesses is well-suited to organisations with high daytime electricity use and long-term occupancy or ownership of their property. Strong candidates include:
Every site is different, so the first step is a technical and financial assessment. As your private PPA provider, we will review your facility and estimate whether the project is likely to deliver useful savings. The best projects usually have the following:
A clear desire to reduce operating costs without capital investment
Actual results depend on the site and energy profile, but Kunini will prepare a tailored savings forecast before you decide whether to sign a private PPA. Savings depend on several factors, including:
The financial impact can be significant.For example, a business with an average electricity bill of THB 250,000 per month may save THB 25,000 to 50,000 per month (THB 300,000 to 600,000 per year).A private PPA for businesses can potentially save several million Baht over the contract term.

Kunini has provided electrical and solar engineering, procurement, and construction (EPC) services in Thailand, with the following features and benefits:
We embody building experience and expertise across a range of areas, including:
As a dedicated private PPA developer, we provide a comprehensive, end-to-end service with no operational disruption. Our in-house team manages all aspects, including:
Kunini supports customers from Hua Hin, Pattaya, and Bangkok, with nationwide project experience. Because a private PPA solar setup is a long-term relationship, responsive service, clear accountability, and no operational disruption are critical from the first assessment through to long-term system functionality. Qualified Engineers, licensed electricians, adherence to strict Thai standards, and IEC-compliant equipment make it the ideal choice for the following:
A PPA private company agreement can include:
Typical timelines vary by project size, location, and utility requirements, but a typical structure (subject to utility approvals where applicable) is as follows:
During the private PPA term, the system is owned by Kunini or its investment partner. This allows your business to use solar electricity without upfront investment or maintenance responsibility. Ownership will transfer to the customer at the end of the agreement.
Kunini manages monitoring, maintenance, insurance, and performance support throughout the contract period.
Savings vary by site, tariff, operating hours, system size, and electricity consumption profile. Many suitable businesses achieve immediate savings compared with buying electricity from utility providers.
Kunini typically reviews the following:
Your assessment can include the recommended system size, estimated annual generation, proposed PPA rate, projected savings, contract options, and environmental benefits. This gives your team a clear basis for comparing solar with current PEA or MEA electricity tariffs before deciding whether a private PPA is the right option.
