Energize Eastside
Energize Eastside is a Puget Sound Energy (PSE) project to upgrade 16 miles of electric transmission line on the Eastside between Redmond and Renton. The project involves building a new electric substation and upgrading lines from 115 kV to 230 kV along the existing easement. The project has faced significant local opposition over its necessity and impact. History The power corridor was originally built in the 1960s, and serves as the backbone of the Eastside's power grid. The route follows the Olympic pipeline. Since then, the Eastside's population has grown significantly. In 2013, PSE announced the need for an upgrade to the Eastside's power grid, citing this population increase. PSE ultimately selected to upgrade the existing corridor, known as "Willow 1" rather than use a parallel one owned by Seattle City Light or use alternatives such as batteries. The plan includes upgrading the 115 kV lines to 230 kV, and building a new electric substation. The project will be paid for ...

Coal Creek Parkway Transmission Lines
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other Chemical element, elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat which is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous (Pennsylvanian (geology), Pennsylvanian) and Permian times. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its Electricity generation, electricity.
