European Union Makes History: Solar Power Plants Replace Coal as Main Source of Electricity

For the first time in history, solar power production in the European Union has surpassed coal-fired power plants. A recent report released by the climate thinktank Ember shows that by 2024, solar power will contribute 11% of total electricity production in the European Union. In contrast, coal-fired power plants' contribution will shrink to 10%, indicating a significant decrease in dependence on fossil fuel sources.

This figure may seem small, but its success in overtaking coal, which has been the backbone of the energy industry for centuries, is an achievement that deserves a thumbs up.

This phenomenon marks the acceleration of the clean energy transition in Europe, driven by increasing solar power capacity and policies to reduce dependence on fossil fuels.

The European Union is on track to achieve its ambitious target of having an installed solar power capacity of 400 gigawatts (GW) by 2025. Awesome!

Driving Factors for Solar Energy Growth

Some of the key factors driving solar energy’s surge over coal include:

1. Large Investments in Renewable Energy

The European Union has been aggressively building solar power generation capacity in recent years, especially in countries such as Germany, Spain, and the Netherlands.

2. Declining Coal Use

Europe’s coal consumption has steadily declined since 2018 due to stricter environmental policies and rising carbon prices, making coal-fired power plants less competitive.

3. Impact of the Global Energy Crisis

Russia’s invasion of Ukraine in 2018 caused a spike in energy prices and prompted European countries to accelerate the transition to cleaner, more sustainable energy sources.

Positive Impacts for the Environment and Economy

Solar’s ​​success in outperforming coal brings several benefits to the environment and the EU’s economy. With more clean energy being produced, carbon emissions can be significantly reduced, supporting the emission reduction targets set in the Paris Agreement. In addition, the EU’s dependence on fossil fuel imports is reduced, increasing energy resilience amid geopolitical uncertainty.

However, challenges remain, especially in terms of infrastructure and grid stability. Intermittent solar energy requires more sophisticated storage and distribution systems to be optimally utilized.

With this trend, renewable energy is expected to continue to grow, while the role of coal in the EU's energy mix will continue to shrink. This success is clear evidence that the transition to clean energy is not only possible but also increasingly inevitable.

Implementation of the Rooftop Solar Power Quota System: Supporting the Stability of the National Electricity Grid

Since July 2024, the Indonesian government has officially implemented a quota system for installing rooftop Solar Power Plants (PLTS) connected to the PLN grid as stated in the Regulation of the Minister of Energy and Mineral Resources No. 2 of 2024. This policy is a strategic step in managing the integration of renewable energy into the national electricity system while supporting the energy transition target towards Net Zero emissions by 2060.

This quota system is designed to ensure that the use of rooftop PLTS is balanced with the capacity of the PLN grid, avoiding excess power that can disrupt the stability of the electricity system. In supporting the Net Zero Emission target of 2060 or sooner, the government has set a quota of 1.5 GW for Rooftop PLTS until 2028. Meanwhile, for each region, the Government sets a quota based on the system capacity which will be evaluated and updated periodically by the Ministry of Energy and Mineral Resources (ESDM). The quota system will be opened in 2 periods a year, namely January and July.

In its implementation, prospective rooftop solar power users must first register their installations through the government's application or digital platform in January and July. This registration will include a technical verification process and quota allocation. If the quota in an area is full, prospective users can be put on a waiting list and will receive confirmation at the opening of the next period.

This quota system also includes an incentive scheme for users who successfully integrate high-efficiency rooftop solar power plants, such as installation fee discounts or carbon credits. Thus, it is hoped that the community will remain motivated to participate in the development of renewable energy, even though there are restrictions through quotas.

The government continues to educate the public and stakeholders regarding the implementation of this system, including its benefits in supporting national energy sustainability. With a planned and collaborative approach, the implementation of the quota system is expected to not only increase the efficiency of rooftop solar power plant use but also encourage innovation in renewable energy technology in the future.

Can Solar Power Plants Still Work During Rainy Conditions?

Solar Power Plants (PLTS) are one of the renewable energy solutions that are increasingly in demand because they are environmentally friendly and have abundant energy sources, namely sunlight. However, one question that often arises is: can PLTS still work when the weather is cloudy or rainy?

Before going any further, let's first find out how PLTS itself works. Yes, as we know, PLTS works by converting solar energy into electrical energy through solar panels containing photovoltaic cells. These cells capture photons from sunlight and convert them into direct current (DC). This electricity is then converted into alternating current (AC) by the inverter so that it can be used by household electrical devices or distributed to the electricity grid.

However, the question arises, when conditions are cloudy or even rainy, does it affect the performance of the PLTS, here is the explanation.

PLTS performance is influenced by the intensity of sunlight received by the solar panels. On a sunny day, solar panels work with optimal efficiency because sunlight directly reaches the surface of the panel. However, when the weather is cloudy or rainy, the intensity of sunlight decreases because it is blocked by clouds.

However, PLTS can still generate electricity in cloudy or rainy conditions, but with lower efficiency. This happens because sunlight is still scattered and reaches the surface of the panel, although in smaller quantities. The decrease in efficiency usually ranges from 10-25%, depending on the level of cloud density and the type of solar panel used.

Not only that, besides affecting efficiency, rain also has its own benefits for PLTS. Rainwater helps clean the surface of the solar panel from dust, dirt, or other pollutants that can reduce the absorption of sunlight. Thus, clean solar panels can work optimally again after the rain stops.

With that, the question "Can PLTS still work in rainy conditions?" The answer is "Yes" PLTS can still work in rainy conditions, although its efficiency decreases compared to when the weather is sunny. However, this decrease does not make PLTS completely non-functional. With good maintenance and technology that continues to develop, PLTS remains a reliable choice for generating environmentally friendly electrical energy, even in areas with weather that is not always sunny.

The use of energy storage batteries is also a solution to ensure that electricity supply is always available at any time, regardless of weather conditions. That way, PLTS remains a promising investment for the future of sustainable energy.

Getting to Know the Advantages and Disadvantages of Floating Solar Power Plants in Indonesia

Floating photovoltaic power plants (PLTS) are an innovative solution that is currently growing rapidly in Indonesia as an alternative to environmentally friendly power plants.

Analysis by the Institute for Essentials Services Reform (IESR) states that the potential for floating PLTS in Indonesia reaches 28.4 Gigawatts (GW). This potential is spread across 783 reservoirs and lakes, each of which has a minimum potential of 1 Megawatt (MW).

It is no wonder that the government is targeting to build 60 floating PLTS in Indonesia while simultaneously pushing the target of a power plant mix from EBT of 23 percent by 2025.

In terms of construction, the installation of floating photovoltaics is equipped with hollow plastic buoys that are designed to withstand extreme weather conditions and the potential for disruption to cables connected to electrical installations on land.

However, because of its character which is installed in water, floating PLTS also has negative impacts. Here are the advantages and disadvantages of floating PLTS (floating photovoltaics).

Advantages of Floating Solar Power Plants

1. Space Utilization

By utilizing the water surface, floating solar power plants save land that is usually used for agriculture, settlements, or industry. This is very relevant in Indonesia, where large land areas are often difficult to obtain for large-scale energy projects.

2. Increase Solar Panel Efficiency

Water has a natural cooling effect that can lower the temperature of solar panels. This lower temperature helps increase panel efficiency, as solar panels are more efficient at lower temperatures.

3. Reduce Water Evaporation

Panels floating on reservoirs or lakes can reduce the rate of water evaporation, which is beneficial for areas prone to drought. This can be a major advantage for water management in Indonesia, especially in areas with long dry seasons.

4. Minimize the Impact on Land Ecosystems

Because floating solar power plants are placed in water, this development will not disturb habitats or convert land areas, which are important in maintaining biodiversity in land ecosystems.

5. Renewable and Clean Energy Source

Like solar power plants in general, floating solar power plants do not produce greenhouse gas emissions or air pollution. This contributes to Indonesia's target of reducing carbon emissions and achieving cleaner energy.

Disadvantages of Floating Solar Power Plants

1. Higher Installation Costs

Additional infrastructure and components, such as buoys, anchors, and waterproof electrical systems, increase the installation costs of floating solar power plants compared to conventional solar power plants on land.

2. More Complicated Maintenance

Floating solar power plants require more complicated maintenance due to the higher risk of corrosion in wet environments and difficult access. Waterproof equipment also requires more costs and more specialized maintenance procedures.

3. Impact on Aquatic Ecology

Shades from solar panels and the presence of structures above the water can reduce sunlight entering the water, which may disrupt aquatic ecosystems, especially in terms of photosynthesis of aquatic plants.

4. Vulnerable to Weather and Nature

Extreme weather such as strong winds, waves, or earthquakes can damage floating PV installations. The system must be designed very robustly to withstand Indonesia's diverse weather, especially during the rainy season or in areas prone to earthquakes.

5. Potential Disturbance to Water Activities

Reservoirs and lakes are often used for other activities, such as irrigation, fisheries, or tourism. Floating PV can reduce the area that can be used for these activities or interfere with fishing boat routes.

Floating PV offers great potential as a renewable energy solution in Indonesia, especially to optimize the use of space and preserve water resources.

Realistically, however, floating PV is unlikely to replace large-scale power plants or the increasing trend of onshore PV anytime soon. But it is very possible that they can fill an important complementary role, adding capacity that is currently lacking.
