Project Overviewx
The award‑winning 1.453 MWp solar rooftop project is one of the most notable installations developed under the BLT (Build – Lease – Transfer) scheme, a model pioneered by PROINSO in collaboration with its local partner VU PHONG ENERGY GROUP and financed by ECOLIGO.
Lac Long is one of PROINSO’s pioneering projects in Vietnam using the BLT partnership model. The project reflects the agility of all partners in recognizing the benefits of solar power and the rapid growth of renewable energy adoption in Vietnam. Operating within the Nail Spa industry, LAC LONG COMPANY distributes products across several major global markets, and this solar initiative enables them to demonstrate a strong commitment to high‑quality service while reducing their environmental impact.
Under this model, businesses can utilize idle rooftop space at their facilities. They may choose to rent the solar system or buy back clean electricity at a rate lower than their current utility costs. At the end of the contract term, the entire system is transferred back to the business free of charge, with a guaranteed remaining capacity of 80–90% depending on system conditions.
The BLT framework represents a win‑win solution for businesses, investors and EPC contractors. It enables companies to adopt green production, secure low‑cost clean energy and avoid upfront capital expenditure. The model is especially well suited for organizations aiming to prioritize investments in technology upgrades, expand production capacity or focus on research and development. Since only around 20% of the system’s capacity is fed into the national grid, this approach supports Vietnam’s renewable energy development and greenhouse‑gas reduction goals without placing additional pressure on transmission and distribution networks.
The project will:
– Reduce CO₂ emissions by more than 1,843 tons per year
– Generate approximately 2,105 MWh of electricity annually
– Protect the environment, equivalent to planting over 81,000 trees
