4. Average utilization hours: an indicator reflecting the degree of equipment utilization of power generating equipment according to nameplate capacity.
Average utilization hours of power generation equipment = power generation / average capacity of power generation equipment

7. Wind power wind abandonment rate: refers to the ratio of the amount of electricity that can be generated but not issued by the wind farm (wind abandonment electricity) to the total amount of electricity that should be generated due to the influence of factors such as grid transmission channels or safe operation needs.
Wind power abandonment rate = wind power abandonment / (actual wind power generation + wind power abandonment)

36. Calculation method of the amount of standard coal replaced by geothermal energy for heating/cooling: Q=P×h, where: P is the heating/cooling load of the building, and the heating load refers to the specification for geothermal investigation of geothermal resources (GB/T 11615-2010) with a value of 50W/m2; and the cooling load refers to the Practical Heating and Air-conditioning Design Manual with a value of 150W/m2. h is the annual heating/cooling time, and the recommendation for a single heating project is 4 months; and the sum of the heating and cooling time of a heating/cooling project is 6 months. The sum of heating and cooling time of the heating/cooling project is suggested to be 6 months. The amount of standard coal replaced by heating and cooling for heating/cooling projects is calculated separately. The above methods are for reference, and can be optimized and adjusted according to the actual situation in each place. (Example: a place in the north, with a 4-month heating season, 10,000 square meters of heat supply Q = 10,000 × 50 × 4 × 30 × 24 × 3600 = 5,184,000 MJ; 1 kilogram of standard coal has a heat capacity of 29.307 MJ, which translates into 177 tons of standard coal per 10,000 square meters of heat supply per heating season.)
