An electric thermal storage heater is a stand-alone, off-peak heating system that eliminates the need for a backup fossil fuel heating system that is wall-mounted and looks a bit like a radiator that contains a ‘bank’ of specially designed, high-density ceramic bricks. These bricks can store vast amounts of heat for extended periods of time. [pdf]

Batteries are classified into primary and secondary forms: • Primary batteries are designed to be used until exhausted of energy then discarded. Their chemical reactions are generally not reversible, so they cannot be recharged. When the supply of reactants in the battery is exhausted, the battery stops producing current and is useless. A battery consists of some number of voltaic cells. Each cell consists of two half-cells connected in series by a conductive electrolyte containing metal cations. [pdf]

Electric storage heaters use electricity to generate heat. They store this heat inside their core, which is often made from heavy clay blocks. Older storage heaters use input and output dials to control heat. The input controls the electricity – the higher you set it, the more electricity it will use and the more the heater will heat up at night. [pdf]

Black start refers to the ability of a power plant to restart parts of the power system after a blackout1. During a blackout, isolated power stations are started individually and gradually reconnected to form an interconnected system again. Gas-fired power plants eligible for black start must be able to run for 16 hours without grid-supplied power2. These plants provide the initial energy needed to activate the power grid during recovery3. [pdf]
