A high-quality modern grid-tie inverter has a fixed unity power factor, which means its output voltage and current are perfectly lined up, and its phase angle is within 1° of the AC power grid. The inverter has an internal computer that senses the current AC grid waveform, and outputs a voltage to correspond with the grid. However, supplying ...
A grid-tied electrical system, also called tied to grid or grid tie system, is a semi-autonomous electrical generation or grid energy storage system which links to the mains to feed excess capacity back to the local mains electrical grid. When insufficient electricity is available, electricity drawn from the mains grid can make up the shortfall ...
Oklahoma assesses a State level excise tax on insurance premiums paid across the State. The insurance tax is collected by the Oklahoma Insurance Department. While most of the insurance tax is deposited within the General Fund, the revenues also support the Insurance Department and provide revenues for the State's employee retirement systems.

Oklahoma State Question 777 was a referendum on a proposed amendment to the Oklahoma Constitution held in November 2016. The referendum attempted to exempt agriculture and agribusiness from compliance with state laws passed in 2015 and later, unless a "compelling state interest" was involved. The referendum was hotly controversial.
An inverter-based resource (IBR) is a source of electricity that is asynchronously connected to the electrical grid via an electronic power converter ("inverter"). The devices in this category, also known as converter interfaced generation (CIG), include the variable renewable energy generators (wind, solar) and battery storage power stations. [1]
