As an expert in the field of energy and urban planning, I can provide a detailed answer to your question about the megawatt requirements to power a city. The amount of power needed to supply a city can vary greatly depending on numerous factors, including the city's size, population, industrial activity, energy efficiency measures, and the time of day or year.
Firstly, it's important to understand the basic unit of measurement. A megawatt (MW) is a unit of power that indicates the rate at which energy is being used or generated. One megawatt is equivalent to one million watts. The energy consumed over time is often measured in megawatt-hours (MWh), which is the product of power (in megawatts) and time (in hours).
Secondly, the energy consumption of a city is not constant; it fluctuates with daily and seasonal cycles. During peak hours, such as early evening when many people are using electricity for lighting and heating, the demand for power is higher than during the night when demand is typically lower.
Thirdly, the efficiency of power generation and distribution also plays a role. Not all the power generated is delivered to consumers due to losses in transmission and distribution. Therefore, more power must be generated to account for these losses.
Now, let's consider some figures. According to some studies, a city with a population of around 80,000 might require approximately 45 MW to meet its needs[^6^]. However, this is a rough estimate and the actual requirement can be higher or lower. Larger cities with populations in the millions would obviously require much more power. For instance, a city with a population of 1 million could potentially require around 100 times the power of a small city, which would be in the range of 4,500 MW, assuming a linear scale-up. However, this is a simplified calculation and real-world scenarios are much more complex.
Moreover, it's crucial to consider the diversity of energy demands within a city. Residential areas, commercial districts, and industrial zones each have different power needs. Additionally, modern cities are increasingly focusing on energy efficiency and the use of renewable energy sources, which can reduce the overall demand for power from traditional sources.
Furthermore, the energy mix of a city is also significant. Some cities may rely heavily on nuclear, hydroelectric, or fossil fuel power plants, while others might have a more diversified mix that includes solar, wind, and other renewable sources. The reliability and capacity factor of these different energy sources can greatly affect the total amount of power that needs to be generated.
In conclusion, determining the megawattage needed to power a city is a complex task that involves analyzing a wide range of variables. It requires a deep understanding of the city's energy infrastructure, consumption patterns, and future growth projections. While the figures mentioned can provide a starting point for discussion, a detailed assessment would be necessary for a precise calculation.

Roughly 10000 megawatt hours per 1 million (yearly). 1 MW can power as many as 1000 homes. And other studies suggest that 45 MW can power a small city of 80,000.
