| 3 | Puget Energy had a derivative liability and an offsetting regulatory asset of $128.5 million at June 30, 2010 and $67.1 million at December 31, 2009 related to financial contracts used to economically hedge the cost of physical gas purchased to serve natural gas customers.  All fair value adjustments on derivatives relating to the natural gas business have been reclassified to a deferred account in accordance with ASC 980, “Regulated Operations,” (ASC 980) due to the Purchased Gas Adjustment (PGA) mechanism.  All increases and decreases in the cost of natural gas supply are passed on to customers with the PGA mechanism and the gains and losses on the hedges in future periods will be recorded as gas costs. |

| ·   | Increase in purchased electricity and electric generation fuel of $9.9 million despite a 1.3% reduction in electric customer retail sales volumes due primarily to the use of higher cost resources.  The increase in power costs is due to lower hydroelectric generation offset by wind generation which caused an increase of $9.2 million.  Additionally, PSE increased the generation from combustion turbines and coal fired plants which increased production costs. |
|--------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | Increase in net unrealized loss on derivative instruments of $19.0 million primarily due to falling forward market prices of electricity and natural gas on de-designation of cash flow hedges related to PSE’s energy contracts.  PSE discontinued cash flow hedge accounting July 1, 2009. |
|--------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | Increase in interest expense of $3.7 million primarily due to increase in long-term debt outstanding issued to fund PSE’s capital expenditures. |

| ·   | Increase in purchased electricity and electric generation fuel of $12.1 million despite a 6.0% reduction in electric customer retail sales volumes due primarily to warmer temperatures in the Pacific Northwest.  The increase in power costs is due to lower hydroelectric and wind generation for which replacement power costs caused an increase of $22.5 million.  Additionally, PSE increased the generation from combustion turbines and coal fired plants which increased production costs. |

| ·   | Increase in interest expense of $11.7 million primarily due to a $6.9 million write off of a regulatory asset for deferred interest paid to the Internal Revenue Service (IRS) related to the Simplified Service Cost Method deduction in prior years which was disallowed for the rate of recovery in the general rate case order of April 2, 2010. |

| ·   | The above increases were partially offset by a decrease from one time merger costs of $23.9 million related to the merger of Puget Energy with Puget Holdings.  These costs were primarily related to PSE employee compensation triggered by Puget Energy’s change of control, credit agreement related expenses and the impact of increases in the deferred compensation related liability. |

| 1 | Puget Energy’s interest expense includes elimination adjustments of intercompany interest on short-term debt. |

| ·   | Puget Energy’s net income for the three months ended June 30, 2010 was negatively impacted by $4.4 million change in net unrealized gain on derivative instruments as a result of the required recognition of all contracts at fair value as part of purchase accounting, including derivative contracts previously designated as Normal Purchase Normal Sale (NPNS).  Certain of these contracts were subsequently redesignated as NPNS.  The unrealized gain represents amortization of the fair values recorded. |

| ·   | Puget Energy’s net loss for the six months ended June 30, 2010 as compared to net income for the same period in 2009 was positively impacted by a $37.4 million change in net unrealized gain on derivative instruments as a result of the required recognition of all contracts at fair value as part of purchase accounting, including derivative contracts previously designated as NPNS.  Certain of these contracts were subsequently redesignated as NPNS.  The unrealized gain represents amortization of the fair values recorded. Puget Energy’s net income for the same period was negatively impacted by $12.9 million of interest expense due to the long-term debt at Puget Energy, and business combination fair value of PSE’s debt, and PSE’s deferred debt costs. |

| ·   | no additional first mortgage bonds under PSE’s natural gas mortgage indenture.  Although PSE had approximately $390.0 million of gas bondable property available for issuance, the Company is subject to a combined gas and electric interest coverage test of 1.75 times net earnings available for interest and a gas interest coverage test of 2.0 times net earnings available for interest (as defined in the natural gas utility mortgage).  At June 30, 2010, PSE exceeded the gas 2.0 times net earnings test, but did not meet the combined 1.75 times test primarily as a result of lower energy sales and higher net power costs due to warmer than normal temperatures and lower than normal hydroelectric and wind generation.  The company expects to meet this test by December 2010 as it collects additional revenues from the April 8, 2010 rate increase for electric and natural gas customers. |
