Coordinating hydropower and wind power satisfies hourly operation requirement. Swedish government's target is to have 100% renewable electricity production by 2040. Currently, hydropower contributes the majority of renewable electricity generation of the country. The wind power capacity has increased significantly in the past decade.
In the recent decade, wind power capacity in Sweden has increased significantly. The electricity generation from wind power in 2009 was 2.5 TWh, which was 1.87% of the total electricity generation of the year. In 2019, it increased to 19.9 TWh, which is 12.1% of the total electricity generation.
The target wind power capacity 25,000 MW is around triple of current existing wind power capacity in Sweden. In other words, if the wind power capacity can be tripled from 2019, it is possible to reach a 100% renewable electricity generation system in Sweden.

Base stations are important in the cellular communication as it facilitate seamless communication between mobile devices and the network communication. The demand for efficient data transmission are increased as we are advancing towards new technologies such as 5G and other data intensive applications.
These types of objects are an inevitability since they serve the purpose of providing signal transfer for data and voice between mobile mobiles. The idea of base stations is anchored in their function to provide coverage, capacity, and connectivity, hence allowing for extending the working capabilities of mobile phones and other radio gear.
The base station is a transceiver and acts as an interface between a mobile station and network using microwave radio communication. It consist of three part elements: one or more transceivers, several antenna mounted on a tower or building, power system, and air conditioning equipment.
The main focus is on reducing losses and improving efficiency. Weak current primarily deals with information transmission and control, characterized by low voltage, low current, low power, and high frequency. The primary concern is the effectiveness of information transmission, such as fidelity, speed, range, and reliability.
