Note H – Other Material Contingencies Manhattan Steam Main Rupture In July 2007, a CECONY steam main located in midtown Manhattan ruptured.
It has been reported that one person died and others were injured as a result of the incident.
Several buildings in the area were damaged.
Debris from the incident included dirt and mud containing asbestos.
The response to the incident required the closing of several buildings and streets for various periods.
Approximately ninety suits are pending against the company seeking generally unspecified compensatory and, in some cases, punitive damages, for wrongful death, personal injury, property damage and business interruption.
The company has notified its insurers of the incident and believes that the policies in force at the time of the incident will cover the company’s costs to satisfy its liability to others in connection with the suits.
In the company’s estimation, there is not a reasonable possibility that an exposure to loss exists for the suits that is materially in excess of the estimated liability accrued.
At December 31, 2015, the company has accrued its estimated liability for the suits of $50 million and an insurance receivable in the same amount.
Manhattan Explosion and Fire On March 12, 2014, two multi-use five-story tall buildings located on Park Avenue between 116th and 117th Street in Manhattan were destroyed by an explosion and fire.
CECONY had delivered gas to the buildings through service lines from a distribution main located below ground on Park Avenue.
Eight people died and more than 50 people were injured.
Additional buildings were also damaged.
The National Transportation Safety Board (NTSB) investigated.
The parties to the investigation included the company, the City of New York, the Pipeline and Hazardous Materials Safety Administration and the NYSPSC (which also conducted an investigation).
In June 2015, the NTSB issued a final report concerning the incident, its probable cause and safety recommendations.
The NTSB determined that the probable cause of the incident was (1) the failure of a defective fusion joint at a service tee (which joined a plastic service line to a plastic distribution main) installed by the company that allowed gas to leak from the distribution main and migrate into a building where it ignited and (2) a breach in a City sewer line that allowed groundwater and soil to flow into the sewer, resulting in a loss of support for the distribution main, which caused it to sag and overstressed the defective fusion joint.
The NTSB also made safety recommendations, including recommendations to the company that addressed its procedures for the preparation and examination of plastic fusions, training of its staff on conditions for notifications to the City’s Fire Department and extension of its gas main isolation valve installation program.
Approximately seventy suits are pending against the company seeking generally unspecified damages and, in one case, punitive damages, for wrongful death, personal injury, property damage and business interruption.
The company has notified its insurers of the incident and believes that the policies in force at the time of the incident will cover the company’s costs, in excess of a required retention (the amount of which is not material), to satisfy any liability it may have for damages in connection with the incident.
The company is unable to estimate the amount or range of its possible loss related to the incident.
At December 31, 2015, the company had not accrued a liability for the incident.
Other Contingencies See “Other Regulatory Matters” in Note B and "Uncertain Tax Positions" in Note L.  Guarantees Con Edison and its subsidiaries enter into various agreements providing financial or performance assurance primarily to third parties on behalf of their subsidiaries.
Maximum amounts guaranteed by Con Edison totaled $2,856 million and $2,547 million at December 31, 2015 and 2014, respectively.
A summary, by type and term, of Con Edison’s total guarantees at December 31, 2015 is as follows:
Federal Utility Regulation The Federal Energy Regulatory Commission (FERC), among other things, regulates the transmission and wholesale sales of electricity in interstate commerce and the transmission and sale of natural gas for resale in interstate commerce.
In addition, the FERC has the authority to impose penalties, which could be substantial, including penalties for the violation of reliability and cyber security rules.
Certain activities of the Utilities and the competitive energy businesses are subject to the jurisdiction of the FERC.
The Utilities are subject to regulation by the FERC with respect to electric transmission rates and to regulation by the NYSPSC with respect to electric and gas retail commodity sales and local delivery service.
As a matter of practice, the NYSPSC has approved delivery service rates for the Utilities that include both transmission and distribution costs.
The electric and gas transmission projects in which CET Electric and CET Gas invest are also subject to regulation by the FERC.
See “Con Edison Transmission,” below.
New York Independent System Operator (NYISO) The NYISO is a not-for-profit organization that controls and operates most of the electric transmission facilities in New York State, including those of the Utilities, as an integrated system.
It also administers wholesale markets for electricity in New York State and facilitates the construction of new transmission it considers necessary to meet identified reliability, economic or public policy needs.
The New York State Reliability Council (NYSRC) promulgates reliability standards subject to FERC oversight.
Pursuant to a requirement that is set annually by the NYSRC, the NYISO requires that entities supplying electricity to customers in New York State have generating capacity (owned, procured through the NYISO capacity markets or contracted for) in an amount equal to the peak demand of their customers plus the applicable reserve margin.
In addition, the NYISO has determined that entities that serve customers in New York City must procure sufficient capacity from resources that are electrically located in New York City to cover a substantial percentage of the peak demands of their New York City customers.
It also requires entities that serve customers in the lower Hudson valley and New York City customers that are served through the lower Hudson valley to procure sufficient capacity from resources electrically located in the lower Hudson valley.
These requirements apply both to regulated utilities such as CECONY and O&R for the customers they supply under regulated tariffs and to companies such as Con Edison Solutions that supply customers on market terms.
To address the possibility of a disruption due to the unavailability of gas, generating units located in New York City that are capable of using either gas or oil as fuel may be required to use oil as fuel for certain periods and new generating units are required to have dual fuel capability.
RECO, O&R’s New Jersey subsidiary, provides electric service in an area that has a different independent system operator – PJM Interconnection LLC (PJM).
See “CECONY – Electric Operations – Electric Supply” and “O&R – Electric Operations – Electric Supply,” below.
Competition The Utilities do not consider it reasonably likely that another company would be authorized to provide utility delivery service of electricity, natural gas or steam where the company already provides service.
Any such other company would need to obtain NYSPSC consent, satisfy applicable local requirements, install facilities to provide the service, meet applicable services standards, and charge customers comparable taxes and other fees and costs imposed on the service.
A new delivery company would also be subject to extensive ongoing regulation by the NYSPSC.
See “Utility Regulation – State Utility Regulation – Regulators,” above.
Distributed generation, such as solar energy production facilities, fuel cells and micro-turbines, provide alternative sources of energy for the Utilities’ electric delivery customers, as does oil for the Utilities’ gas delivery customers.
Micro-grids and community-based micro-grids enable distributed generation to serve multiple locations and multiple customers.
Other distributed energy resources, such as demand reduction and energy efficiency programs, provide alternatives for the Utilities’ delivery customers to manage their energy usage.
The following table shows the aggregate capacities of the distributed generation projects connected to the Utilities’ distribution systems at December 31, 2015 and 2014:
## Table 2 ##
Purchased power expenses decreased $352 million in 2015 compared with 2014 due to a decrease in unit costs ($381 million), offset by an increase in purchased volumes ($29 million).
Fuel expenses decreased $62 million in 2015 compared with 2014 due to lower unit costs ($69 million), offset by higher sendout volumes from the company’s electric generating facilities ($7 million).
Other operations and maintenance expenses decreased $11 million in 2015 compared with 2014 due primarily to lower pension costs ($85 million), offset in part by an increase in the surcharges for assessments and fees that are collected in revenues from customers ($44 million) and higher electric operating costs ($23 million).
Depreciation and amortization increased $39 million in 2015 compared with 2014 due primarily to higher electric utility plant balances.
Taxes, other than income taxes increased $35 million in 2015 compared with 2014 due primarily to higher property taxes ($31 million) and a sales and use tax refund received in 2014 ($12 million), offset in part by the elimination of the New York City subsidiary capital tax ($6 million) and lower state and local revenue taxes ($3 million).
Gas CECONY’s results of gas operations for the year ended December 31, 2015 compared with the year ended December 31, 2014 is as follows:
## Table 3 ##
CECONY’s gas sales and deliveries, excluding off-system sales, in 2015 compared with 2014 were:
## Table 4 ##
(a) Revenues from gas sales are subject to a weather normalization clause and a revenue decoupling mechanism, as a result of which, delivery revenues are generally not affected by changes in delivery volumes from levels assumed when rates were approved.
(b) After adjusting for variations, principally weather and billing days, firm gas sales and transportation volumes in the company’s service area increased 6.7 percent in 2015 compared with 2014, reflecting primarily increased volumes attributable to additional customers that have converted from oil-to-gas as heating fuel for their buildings.
(c) Includes 1,229 and 6,057 thousands of Dt for 2015 and 2014, respectively, which are also reflected in firm transportation and other.
(d) Other gas operating revenues generally reflect changes in regulatory assets and liabilities in accordance with the company’s rate plans.
