**CAISO Monthly Billed Fuel Cost**.Â [for Geysers Main only] The CAISO Monthly Billed Fuel Cost is given by Equation C2-1. CAISO Monthly Billed Fuel Cost Equation C2-1 = Billable MWh đźźŹ Steam Price ($/MWh) Where: â€˘ Steam Price is $16.34/MWh. â€˘ For purposes of Equation C2-1, Billable MWh is all Billable MWh Delivered after cumulative Hourly Metered Total Net Generation during the Contract Year from all Units exceeds the Minimum Annual Generation given by Equation C2-2. Equation C2-2 Minimum Annual Generation = (Annual Average Field Capacity đźźŹ 8760 hours đźźŹ 0.4) - (A+B+C) Where: â€˘ Annual Average Field Capacity is the arithmetic average of the two Field Capacities in MW for each Contract Year, determined as described below. Field Capacity shall be determined for each six-month period from July 1 through December 31 of the preceding calendar year and January 1 through June 30 of the Contract Year. Field Capacity shall be the average of the five highest amounts of net generation (in MWh) simultaneously achieved by all Units during eight-hour periods within the six-month period. The capacity simultaneously achieved by all Units during each eight-hour period shall be the sum of Hourly Metered Total Net Generation for all Units during such eight-hour period, divided by eight hours. Such eight-hour periods shall not overlap or be counted more than once but may be consecutive. Within 30 days after the end of each six-month period, Owner shall provide CAISO and the Responsible Utility with its determination of Field Capacity, including all information necessary to validate that determination. â€˘ A is the amount of Energy that cannot be produced (as defined below) due to the curtailment of a Unit during a test of the Facility, a Unit or the steam field agreed to by CAISO and Owner. â€˘ B is the amount of Energy that cannot be produced (as defined below) due to the retirement of a Unit or due to a Unitâ€™s Availability remaining at zero after a period of ten Months during which the Unitâ€™s Availability has been zero. â€˘ C is the amount of Energy that cannot be produced (as defined below) because a Force Majeure Event reduces a Unitâ€™s Availability to zero for at least thirty (30) days or because a Force Majeure Event reduces a Unitâ€™s Availability for at least one hundred eighty (180) days to a level below the Unit Availability Limit immediately prior to the Force Majeure Event. â€˘ The amount of Energy that cannot be produced is the sum, for each Settlement Period during which the condition applicable to A, B or C...

**CAISO Monthly Billed Fuel Cost**.Â [for Geysers Units 13 & 16 only] The CAISO Monthly Billed Fuel Cost is given by Equation C2-1. CAISO Monthly Billed Fuel Cost Equation C2-1 = Billable MWh đźźŹ Steam Price ($/MWh) Where: â€˘ Steam Price is $11.25/MWh, which includes the cost of steam condensate re-injection.

**CAISO Monthly Billed Fuel Cost**.Â The CAISO Monthly Billed Fuel Cost is given by Equation C5-1: Equation C4-1 CAISO Monthly Billed Fuel Cost = Billable MWh * Monthly Average Fuel Cost ($MWh) Where: ď‚· Monthly Average Fuel Cost ($ / MWh) = Negotiated Cost Based Amount.

**CAISO Monthly Billed Fuel Cost**.Â The CAISO Monthly Billed Fuel Cost is given by Equation C4-1: Equation C4-1 CAISO Monthly Billed Fuel Cost = Year-to-Date CAISO Fuel Cost â€“ Sum of Previous Monthsâ€™ CAISO Monthly Billed Fuel Cost in the Contract Year Where: â€˘ Year-to-Date CAISO Fuel Cost is given by Equation C4-2. â€˘ Sum of Previous Monthsâ€™ CAISO Monthly Billed Fuel Cost in the Contract Year shall be the sum of the CAISO Monthly billed Fuel Cost for each Month from January 1 of the Contract Year7 through the end of the Month in the Contract Year before the Billing Month. Year-to-Date CAISO Fuel Cost Equation C4-2 đźźŹ = (YTD Pumping Cost/YTD Energy Produced) Variable O&M Rate Where: â€˘ YTD Pumping Cost =Total cost of Energy purchased by Owner for pumping, including transmission charges, from January 1 of the Contract Year through the end of the Billing Month. â€˘ YTD Energy Produced =Total Energy produced by the Facility for Market and Nonmarket Transactions from January 1 of the Contract Year through the end of the Billing Month. â€˘ YTD Billable MWh =Total Billable MWh from January 1 of the Contract Year through the end of the Billing Month.
