Disclosed herein are apparatus, methods, and systems for grounding outdoor light poles, as well as other structures, which may be exposed to lightning or other adverse electrical effects and may require a low impedance path to ground. Inventive aspects include a combination of apparatus integral to the pole or other structure and installation considerations whereby the ease of installation, reduction of onsite installation error, and reduction of impedance may be tailored to each installation. An apparatus can include a pre-installed earth grounding electrode at the lower end of the pole or structure to be inserted into the earth. A method can include installing an earth grounding electrode to/on/in a lower end of a pole or structure prior to insertion into the earth.
