Hydroelectric Power: How it works, USGS WaterScience School
In both cases a power source is used to turn a propellerlike piece called a turbine, which then turns a metal shaft in an electric generator, which is the motor that produces electricity. A coalfired power plant uses steam to turn the turbine blades; whereas a hydroelectric plant uses falling water to turn the turbine. The results are the same.

When coal is burnt to produce heat energy, this heat energy can be used to create steam. The steam drives the steam turbine, which is connected to a generator. The energy produced by the generator is passed through a transformer into the National Grid transmission line. This is the system that delivers electricity to all of New Zealand.

The most promising 'clean coal' technology involves using the coal to make hydrogen from water, then burying the resultant carbon dioxide byproduct and burning the hydrogen. The greatest challenge is bringing the cost of this down sufficiently for 'clean coal' to compete with nuclear power on the basis of nearzero emissions for baseload power.

Fossil fuel power station Wikipedia
A fossil fuel power station is a power station which burns a fossil fuel such as coal, natural gas, or petroleum to produce electricity. Central station fossil fuel power plants are designed on a large scale for continuous operation. In many countries, such plants provide most of the electrical energy used.

The quality of coal. Since we are converting the energy in coal to electricity, we need to know the energy content of coal. A quick googling tells me that the energy content of coal is given in terms of MegaJoules (Mj) per Kilogram (kg) of coal as the Gross calorific value (GCV) or the Higher Heating value (HHV). This value can vary from Mj/kg to 24 Mj/kg depending on the quality and type of the coal.
