A downhole electrical power generation apparatus includes first and second fluid receiving chambers 21a, 21b. A fluid communication path 24a is present between the chambers and a turbine generator 26 is disposed so that fluid flowing from the first chamber 21a to the second chamber 21 b operates the turbine generator 26 to generate electrical power. Stored pressurised gas and/or ambient downhole pressure may be used to force the fluid between the chambers 21a, 21 b. |
