Power Plant Capacity: Ensure sufficient power generation to meet city demand
In Cities: Skylines, ensuring that your buildings have access to electricity is crucial for the functionality and growth of your city. One of the primary reasons buildings may not be using electricity is insufficient power generation capacity. Power Plant Capacity is a critical factor, as it directly determines whether your city can meet its energy demands. To address this, start by evaluating your current power generation setup. Check the total electricity production of your power plants against the city’s consumption. If the demand exceeds the supply, buildings will not receive power, leading to inefficiency and dissatisfaction among citizens. Use the electricity demand graph in the game to monitor peak usage times and plan accordingly.
Expanding your power generation capacity is essential to meet growing demand. Begin by building additional power plants or upgrading existing ones. Diversify your energy sources by incorporating renewable options like wind turbines, solar farms, or hydroelectric plants, which provide consistent power without pollution. However, be mindful of their placement, as some renewable sources are location-dependent (e.g., wind turbines require open, windy areas). Avoid relying solely on one type of power plant, as this can lead to vulnerabilities in your energy grid, especially if fuel supplies (like coal or oil) become scarce.
Another aspect to consider is the transmission network. Even if your power plants generate sufficient electricity, buildings may not receive it if the transmission lines are overloaded or poorly connected. Ensure that power lines or substations are strategically placed to cover all areas of your city. Use the electricity overlay to identify gaps in coverage and upgrade transmission lines as needed. High-voltage power lines can transmit electricity over longer distances, reducing the strain on your grid and ensuring a stable supply to all buildings.
Balancing power generation with consumption is key to maintaining a reliable electricity supply. Monitor your city’s growth and plan ahead by building power plants before demand peaks. Overbuilding slightly can provide a buffer during unexpected spikes in usage. Additionally, consider implementing energy-efficient policies or zoning regulations to reduce overall demand. For example, residential and commercial zones with access to public transportation or green spaces tend to consume less electricity, easing the burden on your power grid.
Lastly, regularly maintain and upgrade your power infrastructure. Older power plants may become less efficient over time, reducing their output. Demolish or replace outdated facilities to ensure maximum generation capacity. Similarly, upgrade substations and transmission lines to handle higher loads as your city expands. By proactively managing your power plant capacity and distribution network, you can ensure that all buildings in your city have consistent access to electricity, fostering growth and citizen happiness.

Power Line Connections: Check if buildings are connected to the power grid
In Cities: Skylines, ensuring that your buildings are properly connected to the power grid is crucial for their functionality. One of the primary reasons buildings may not be using electricity is due to inadequate or missing power line connections. To address this issue, start by visually inspecting your power grid. Zoom in on the affected areas and look for gaps or breaks in the power lines. Power lines must form a continuous network from the power plant to the buildings. If you notice any disconnected segments, this is likely the root cause of the problem. Use the power line tool to extend or reconnect the lines, ensuring a direct path to the buildings in question.
Next, verify that the power lines are correctly placed and within range of the buildings. Power lines must be close enough to the buildings to provide electricity, typically within a few tiles. If the lines are too far away or improperly routed, buildings will not receive power. Pay attention to the terrain and obstacles, as power lines cannot pass through buildings or certain terrain features. Adjust the placement of the lines as needed, ensuring they follow a logical path and are within the required distance of the buildings. Additionally, check for any overlapping or crossed lines, as these can sometimes cause connectivity issues.
Another common oversight is forgetting to connect substations or power poles to the main grid. Substations act as distribution points for electricity, and if they are not connected to the power plant via power lines, the buildings they serve will remain unpowered. Ensure that each substation is linked to the main grid by tracing the power lines back to the power plant. If a substation appears isolated, use the power line tool to connect it to the nearest active line. This step is particularly important in larger cities where the power demand is high and the grid is more complex.
For residential, commercial, and industrial buildings, the game provides visual cues to indicate their power status. Look for the power icon on each building; if it appears red or shows a lightning bolt with a slash through it, the building is not receiving electricity. Once you’ve confirmed the power line connections, these icons should update to green, indicating successful power delivery. If the issue persists, double-check the connections and ensure there are no hidden gaps or errors in the grid.
Lastly, consider the capacity of your power grid. While this is a separate issue from connectivity, it’s worth mentioning as it can sometimes be confused with connection problems. If your power plant’s output is insufficient to meet the city’s demand, buildings may not receive electricity even if they are connected. Monitor your power usage and production levels, and upgrade your power infrastructure as needed. However, if the issue is specifically about buildings not using electricity despite being connected, focus on the integrity and placement of your power lines to resolve the problem.

Maintenance Issues: Verify power plants are not abandoned or lacking maintenance
In Cities: Skylines, one of the primary reasons buildings may not be using electricity is due to maintenance issues with your power plants. It’s crucial to verify that your power plants are not abandoned or lacking maintenance, as this directly impacts their ability to generate and distribute electricity. Abandoned power plants stop producing power entirely, leaving connected buildings without electricity. To check for abandonment, zoom in on your power plants and look for a small, red "abandoned" icon or a lack of activity around the facility. If a plant is abandoned, it must be demolished and replaced, as there is no in-game mechanic to reactivate it.
Maintenance is another critical factor that can cause power plants to underperform or stop functioning altogether. Power plants require regular upkeep to operate efficiently. If a plant is lacking maintenance, its output will decrease, and it may eventually shut down. To assess maintenance levels, open the power plant’s information panel by clicking on it. Look for indicators of low maintenance, such as reduced efficiency or warnings about poor condition. If maintenance is an issue, ensure you have a functional waste management system in place, as garbage accumulation can hinder maintenance crews from reaching the plant.
Additionally, check the road access to your power plants. Maintenance vehicles need clear and direct routes to reach the facilities. If roads are congested, poorly connected, or inaccessible, maintenance crews may struggle to perform their duties, leading to operational issues. Ensure that roads leading to power plants are wide enough and free of traffic jams. Consider using one-way roads or public transport lanes to optimize traffic flow around critical infrastructure.
Another aspect to consider is the placement of power plants in relation to maintenance depots. Maintenance vehicles must travel from their depots to the power plants, so placing plants too far from these depots can delay maintenance. Strategically locate maintenance depots near power plants to minimize response times. If a plant is in a remote area, consider building an additional depot nearby to ensure timely upkeep.
Finally, monitor the overall demand and capacity of your power grid. Overloading a power plant beyond its capacity can lead to wear and tear, increasing the likelihood of maintenance issues. Use the electricity demand map (found in the power menu) to identify areas of high consumption and distribute power plants accordingly. Regularly upgrade or add new plants to meet growing demand and reduce strain on existing facilities. By addressing maintenance proactively, you can ensure your power plants operate efficiently and keep your city’s buildings powered.

Resource Depletion: Confirm fuel sources like coal or oil are not exhausted
In Cities: Skylines, ensuring a steady supply of electricity to your buildings is crucial for the city's functionality and growth. One common issue players encounter is buildings not receiving power, and resource depletion is a significant factor to consider. When your power plants run out of fuel, they will shut down, leading to widespread power outages. To address this, you must first confirm that your fuel sources, such as coal or oil, are not exhausted. These resources are finite, and once depleted, your power plants will cease operation until new supplies are secured.
To check for resource depletion, open the resource panel in the game and examine the levels of coal and oil. If either resource is nearing zero, it’s time to take immediate action. One solution is to build additional resource extraction sites to increase your reserves. For coal, consider constructing more coal mines in areas where deposits are available. For oil, ensure you have enough oil pumps operational. Additionally, monitor the efficiency of your extraction sites, as poorly managed or overworked sites may deplete resources faster than expected.
Another strategy to mitigate resource depletion is to diversify your energy sources. Relying solely on coal or oil makes your city vulnerable to outages when these resources run out. Instead, invest in renewable energy sources like wind turbines, solar panels, or hydroelectric dams. These options provide a sustainable and inexhaustible supply of electricity, reducing the risk of power shortages. Balancing traditional and renewable energy sources ensures a stable power grid even if one resource becomes scarce.
If you’re unable to expand extraction sites or switch to renewables immediately, importing resources is a viable short-term solution. Use the game’s trade depot system to import coal or oil from neighboring cities or external suppliers. This buys you time to develop alternative energy strategies while keeping your power plants operational. However, rely on imports sparingly, as they can be costly and unsustainable in the long run.
Lastly, monitor your power plant’s fuel consumption to anticipate depletion. Each power plant has a finite storage capacity for coal or oil, and once this is exhausted, the plant will shut down. Regularly check the fuel levels of your power plants and plan ahead by ensuring a steady supply of resources. Efficient city planning, including zoning industrial areas near resource extraction sites, can also streamline resource distribution and reduce the risk of depletion. By staying proactive and addressing resource depletion early, you can maintain a reliable electricity supply for your city.

Zoning and Distance: Buildings too far from power lines won’t receive electricity
In *Cities: Skylines*, one of the most common reasons buildings aren’t receiving electricity is due to improper zoning and excessive distance from power lines. The game’s power distribution system requires buildings to be within a certain range of power lines to connect to the grid. If a building is too far from the nearest power line, it won’t receive electricity, regardless of how many power plants you’ve built. This issue often arises in low-density residential or industrial zones that are spread out or located on the outskirts of your city. To address this, ensure that your power lines are strategically placed to cover all zoned areas, especially those farther from the city center.
Zoning plays a critical role in this process. When you zone an area for residential, commercial, or industrial use, the game automatically calculates the distance between the zoned buildings and the nearest power lines. If the distance exceeds the game’s threshold (typically a few hundred meters), the buildings will remain unpowered. To avoid this, zone areas closer to existing power lines or plan your power grid to extend coverage to newly zoned districts. Additionally, use the game’s power line tool to manually connect distant zones, ensuring that electricity reaches every corner of your city.
Another factor to consider is the terrain and layout of your city. Hilly or mountainous regions can complicate power line placement, as the game’s power lines must follow the terrain’s contours. If buildings are located on elevated or isolated areas, they may be too far from the nearest power line, even if it appears close on the map. To solve this, build power lines along roads or use the terrain tool to create flatter areas for easier grid expansion. Alternatively, place substations or additional power lines to bridge the gap between distant zones and the main grid.
Distance also becomes a problem when cities grow rapidly without proper infrastructure planning. As your city expands, new zones may outpace the reach of your existing power grid. To prevent this, adopt a proactive approach by extending power lines ahead of zoning new areas. Use the game’s electricity coverage overlay to identify gaps in your grid and prioritize connecting underserved zones. This ensures that buildings are powered as soon as they are constructed, avoiding the issue of unpowered structures altogether.
Finally, remember that the game’s power system is designed to mimic real-world limitations. Just as in reality, electricity in *Cities: Skylines* cannot travel indefinitely without proper infrastructure. If you notice unpowered buildings, pause the game and assess the distance between those structures and the nearest power lines. Use the power line tool to close the gap, and consider upgrading to higher-capacity power lines (such as high-voltage lines) for more efficient distribution. By focusing on zoning proximity and grid expansion, you can ensure that every building in your city has access to electricity.
