Transmission, Distribution Development & Upgrades:

When there are situations surrounding the need to upgrade or build new transmission and distribution systems for a customer, CES will sit down with a utility company and help to understand and create a solution about ensuring that their transmission, distribution and grid systems can handle the power that CES will be providing into the grid upon operations.

Part of CES expertise is in Transmission, Distribution Development & Upgrades which ensures a customer that the power they are purchasing will get to the end user.  CES Engineers design transmission networks to transport the energy as efficiently as feasible, while at the same time taking into account economic factors, network safety and redundancy. These networks use components such as power lines, cables, circuit breakers, switches and transformers. The transmission network is usually administered on a regional basis by an entity such as a regional transmission organization or transmission system operator.


Transmission efficiency is greatly improved by devices that increase the voltage, (and thereby proportionately reduce the current) in the line conductors, thus allowing power to be transmitted with acceptable losses. The reduced current flowing through the line reduces the heating losses in the conductors. According to Joule's Law, energy losses are directly proportional to the square of the current. Thus, reducing the current by a factor of 2 will lower the energy lost to conductor resistance by a factor of 4.

This increase of voltage is usually achieved in AC circuits by using a step-up transformerHVDC systems require relatively costly conversion equipment which may be economically justified for particular projects such as submarine cables and longer distance high capacity point to point transmission but are infrequently used at present.


The transmission grid is a network of power stations, transmission lines, and substations. Energy is usually transmitted within a grid with three-phase AC. Single-phase AC is used only for distribution to end users since it is not usable for large polyphase induction motors. In the 19th century, two-phase transmission was used but required either four wires or three wires with unequal currents. Higher order phase systems require more than three wires, but deliver marginal benefits.
