The rapid growth of Battery Energy Storage Systems (BESS) and fluctuating electricity prices are driving businesses to adopt smarter energy strategies. Since early 2023, Vietnam Electricity (EVN) has increased electricity prices by 12.5% within just 18 months - making cost-effective energy management more critical than ever. So, how can businesses invest in battery energy storage systems for maximum efficiency?

3 Benefits of investing in Battery Energy Storage Systems

As challenges in maintaining grid stability continue to rise, the demand for energy storage systems to minimize costs and enhance energy efficiency becomes increasingly urgent. Investing in an energy storage system is a strategic move that allows businesses to maximize profits in an ever-changing energy market.

Battery Energy Storage Systems enables the storage of electricity when prices are low and its use during peak hours when prices soar. This not only significantly reduces operating costs but also optimizes energy usage, improving long-term economic efficiency.

How to Invest in Battery Energy Storage Systems for maximum efficiency

There are 2 common investment approaches for deploying a BESS system: the first is to carry it out yourself through installation contractors, and the second is to partner with a comprehensive energy investment provider such as GreenYellow.

1. Self-investment

With the self-investment approach, you have full control over the project—from equipment selection, design, and construction to operation and maintenance. However, the investment cost for an energy storage system is high, and the installation process requires contractors with technical expertise and in-depth understanding of the system. Therefore, finding reputable and suitable partners can be time-consuming and costly.

2. Partnering with a comprehensive energy solutions provider

An alternative approach is to collaborate with an energy solutions provider offering 0-CAPEX upfront investment. In this model, all equipment, design, installation, operation, and maintenance are handled by a third party under contractual agreements, ensuring alignment with business needs. This model is similar to solar power installation through investment partners.

Investing through a comprehensive energy solution provider eliminates the pressures of cost, technical complexities, and operational concerns, while ensuring system performance and maintenance. This is considered a financially flexible solution for your business, allowing you to allocate capital and resources to core business activities instead of making large investments to develop a BESS system on your own.

To reduce emissions and achieve environmental goals, the first step is to measure the carbon footprint of both you and your business. Calculating CO2 emissions is the initial step in assessing energy consumption and its environmental impact. So, what is the CO2 emission factor, and how is it calculated?

What is IPCC CO2 Emission?

The CO2 emission factor according to the IPCC is an index used to measure the amount of greenhouse gas emissions, primarily carbon dioxide (CO2), released when generating a specific amount of electricity. A common unit for expressing the emission factor is tons of CO2 per megawatt-hour (tCO2/MWh) or tons of CO2 equivalent per megawatt-hour (tCO2e/MWh).

The CO2 emission factor reflects the level of CO2 emitted into the environment per unit of energy produced or consumed. A lower or decreasing CO2 emission factor over time indicates that the electricity grid is relying more on clean energy sources such as solar and wind power, rather than fossil fuels like coal or natural gas, which have higher emission factors.

What is the emission factor of Vietnam's national power grid?

We know what the CO2 emission factor according to the IPCC is, but what is the emission factor of Vietnam's national power grid? In Vietnam, the emission factor of the national power grid is announced annually by the Department of Climate Change under the Ministry of Natural Resources and Environment. Below is a table summarizing the greenhouse gas emission factors of Vietnam's power grid from 2014 to 2022.

Currently, there is no official data available for the latest figures. However, you can refer to an article by Dr. Lê Hải Hưng from Hanoi University of Science and Technology, which estimates that the greenhouse gas emission factor of Vietnam’s power grid in 2023 will be 0.6559 tCO₂/MWh.

From 2015 to 2020, the construction of coal and gas-fired power plants led to an increase in the emission factor. However, since 2021, as solar and wind energy began to take up a larger share of the energy mix, this factor has decreased.

According to the VIII Power Development Plan, with the goal of gradually reducing the use of fossil fuel-based power sources and moving towards full reliance on renewable energy to achieve the Net-Zero target by 2050, we can expect that the greenhouse gas emission factor of Vietnam’s power grid will continue to decrease. This means that our electricity will become cleaner, contributing to environmental protection and mitigating the impacts of climate change.

Renewable Energy: The Key to Reducing CO2 Emission Factors

Based on the CO2 emission factor data from the IPCC, renewable energy sources such as solar and wind power are clearly playing a critical role in reducing greenhouse gas emissions. A life cycle assessment (LCA) study from the U.S. National Renewable Energy Laboratory (NREL) shows that transitioning from coal to renewable energy can reduce CO2 emissions by hundreds of millions of tons each year, significantly contributing to slowing climate change.

This result confirms that solar energy is one of the cleanest energy sources when considering its entire life cycle. To mitigate the impacts of climate change, transitioning from coal to renewable energy sources, especially solar power, is an essential step toward a more sustainable future.
