Save energy, contribute to reduce costs in production

Poyun Electronics Vietnam Co., Ltd. (Tran Hung Dao Ward) has invested in a rooftop solar power system to help reduce production costs.

Transition to clean energy

In accordance with Plan No. 205/KH-UBND of the City People's Committee on strengthening electricity saving in the period 2023 - 2025, businesses in the area have simultaneously implemented many solutions to reduce energy consumption, prioritizing the use of high-efficiency equipment and integrating renewable energy sources into production.

The DEEP C Industrial Zones complex (East Hai Phong area) is one of the pioneering units developing according to an ecological model in Vietnam. Currently, the four industrial zones of DEEP C Industrial Zones are replacing old lighting with smart LED lights from Signify, which can automatically adjust brightness at night, optimizing energy use and increasing lamp lifespan. This green transition is estimated to save up to 45% of energy consumption (compared to old halogen lights), while reducing more than 60 tons of CO2 annually.

In addition, the solar energy system at DEEP C Hai Phong includes numerous solar panels installed on the factory roofs and vacant land to generate electricity. Currently, DEEP C has installed over 20MWp of solar panels, contributing to a reduction in annual CO₂ emissions.

According to incomplete statistics, over the past five years of consistently implementing the eco-industrial park model, the unit has saved 5.7 million kWh of electricity annually. This electricity is integrated into the industrial park's internal grid, diversifying the power supply. According to a representative from DEEP C, this is not only an economic solution but also a strategy to enhance environmental value and competitiveness.

In the western part of Hai Phong, Poyun Vietnam Electronics Co., Ltd. (Tran Hung Dao Ward) invested in a rooftop solar power system with 3,468 solar panels and a capacity of 1.9 MW. After just over 8 months of operation, the company has saved approximately 5 billion VND in electricity costs, equivalent to 2 million kWh of electricity. This system currently meets about 80% of the factory's electricity consumption needs, demonstrating clear effectiveness and the potential for replication in the electronics, mechanical engineering, and assembly industries.

Also in the industrial manufacturing sector, Ford Vietnam Co., Ltd. (Viet Hoa Ward) conducted an energy audit and replaced its lighting and air conditioning systems with energy-efficient equipment, while improving ventilation and natural lighting in the factory. The company aims to save at least 2% of its electricity consumption annually and is researching the implementation of a rooftop solar power system to self-supply electricity for its production activities.

These models demonstrate that implementing energy-saving solutions is entirely feasible, yielding economic and environmental benefits, while also aligning with the city's green and sustainable development orientation.

Spreading the electricity saving movement.

In recent years, the electricity saving movement within the business community in Hai Phong has become a targeted program, driven by both government policies and the goal of reducing production costs. The City People's Committee issued a Plan for implementing electricity saving measures for the period 2023–2025 to concretize the Government 's Directive.

Accordingly, the City People's Committee requires production facilities with high consumption to implement clear energy saving targets; at the same time, it encourages the installation of renewable energy sources, the use of high-efficiency energy-labeled equipment, and participation in load adjustment programs when necessary. This plan is not just an administrative document but also creates a legal framework, serving as a prerequisite for businesses to incorporate electricity saving into their production strategies and cost management.

In reality, this policy encourages a shift in investment towards technological solutions. At the enterprise level, projects such as rooftop solar power installations, replacing all lighting with smart LEDs, or applying real-time electricity consumption monitoring systems are becoming popular due to direct economic benefits: reduced energy bills, shorter payback periods, and reduced emissions.

For example, at Poyun Vietnam Electronics Co., Ltd., after just over 8 months of operating a 1.9 MW rooftop solar power system, the company recorded savings of approximately 5 billion VND, equivalent to generating over 2 million kWh of electricity. This result has helped convince many businesses in the same industry to consider the option of "self-production and self-consumption" to reduce their dependence on the grid.

Beyond economic outcomes, policies and technologies must also be guided by the awareness and vision of business leaders and technology partners. At recent conferences, representatives from lighting technology and energy management corporations have consistently emphasized the role of smart lighting and data in optimizing consumption.

Mr. Phung Hoai Duong, General Director of Signify Vietnam, affirmed that transitioning to sustainable production combined with smart energy-saving solutions is the foundation for enhancing the competitiveness of Vietnamese businesses… This assessment shows that technology and data management are key to scaling up effective electricity savings.

However, the transition process still faces significant obstacles. According to representatives from several businesses, initial investment in solar power systems, smart LED equipment, or control systems often requires substantial capital, and while the economic benefits are clear, it takes time to recoup them.

Many small and medium-sized enterprises (SMEs) are still hesitant about the costs, procedures, and operational capabilities of new technologies. Furthermore, in terms of governance, the measurement, monitoring, and reporting of energy savings are not standardized among businesses and between businesses and regulatory agencies, leading to difficulties in evaluating, comparing, and replicating successful models.

These limitations require local authorities, the power sector, and financial partners to collaborate in developing support mechanisms, tax incentives, or technical assistance and operational training programs.
