Competitive Energy Businesses Con Edison pursues competitive energy opportunities through three wholly-owned subsidiaries: Con Edison Solutions, Con Edison Energy and Con Edison Development.
These businesses sell to retail customers electricity purchased in wholesale markets and enter into related hedging transactions, provide energy-related products and services to wholesale and retail customers, and participate in energy infrastructure projects.
At December 31, 2013, Con Edison’s equity investment in its competitive energy businesses was $488 million and their assets amounted to $1,314 million.
Con Edison Solutions Con Edison Solutions primarily sells electricity to industrial, commercial and governmental customers in the northeastern United States and Texas.
It also sells electricity to residential and small commercial customers in the northeastern United States.
Con Edison Solutions does not sell electricity to the Utilities.
Con Edison Solutions sells electricity to customers who are provided delivery service by the Utilities.
It also provides energy efficiency services, procurement and management services to companies and governmental entities throughout most of the United States.
Con Edison Solutions was reported by KEMA, Inc.  in September 2013 to be the 10th largest non-residential retail electricity provider in the United States.
The company sells to retail aggregation entities in Massachusetts, Illinois, and New Jersey as well as to individual residential and small commercial (mass market) customers in the northeastern United States.
At December 31, 2013, it served approximately 159,000 customers, not including approximately 148,000 served under the four aggregation agreements.
Con Edison Solutions’ electricity sales for the last five years were:
## Table 0 ##
(a) Excludes aggregation agreement customers Con Edison Solutions seeks to serve customers in utility service territories that encourage retail competition through transparent pricing, purchase of receivables programs or utility-sponsored customer acquisition programs.
The company currently sells electricity in the service territories of 50 utilities in the states of New York, Massachusetts, Connecticut, New Hampshire, Maine, New Jersey, Delaware, Maryland, Illinois, Pennsylvania, Rhode Island, Ohio and Texas, as well as the District of Columbia.
Approximately 28 percent of the sales volumes were in New York, 28 percent in New England, 35 percent in the District of Columbia, Maryland, New Jersey and Pennsylvania and 9 percent in Texas.
The electricity Con Edison Solutions sold to its customers in 2013 was purchased primarily through wholesale electricity markets administered by the NYISO, PJM, Independent System Operator New England and Electric Reliability Council of Texas.
The company expects that these resources will again be adequate to meet the requirements of its customers in 2014.
Con Edison Energy provides hedging and risk management services to Con Edison Solutions.
Con Edison Solutions also provides energy-efficiency services to government and commercial customers.
The services include the design and installation of lighting retrofits, highefficiency heating, ventilating and air conditioning equipment and other energy saving technologies.
The company is compensated for its services based primarily on the increased energy efficiency of the installed equipment over a multi-year period.
Con Edison Solutions has won competitive solicitations for energy savings contracts with the Department of Energy and the Department of Defense, and a shared energy savings contract with the United States Postal Service.
The company owns renewable energy projects predominately in Massachusetts and California with an aggregate capacity of 18 MW (AC).
Management’s Discussion and Analysis of Financial Condition and Results of Operations – Continued operating expenses attributable to major storms in 2012 and 2011 were deferred as a regulatory asset.
See “Regulatory Assets and Liabilities” in Note B to the financial statements in Item 8.

## Table 1 ##
CECONY’s gas sales and deliveries, excluding off-system sales, in 2012 compared with 2011 were:
## Table 2 ##
(a) Includes 563 and 3,801 thousands of dths for 2012 and 2011, respectively, which are also reflected in firm transportation and other.
CECONY’s gas operating revenues decreased $106 million in 2012 compared with 2011 due primarily to a decrease in gas purchased for resale costs ($131 million), offset in part by higher revenues from the gas rate plan ($25 million).
CECONY’s 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.
Other gas operating revenues generally reflect changes in regulatory assets and liabilities in accordance with the company’s rate plans.
See Note B to the financial statements in Item 8.
CECONY’s sales and transportation volumes for firm customers decreased 7.2 percent in 2012 compared with 2011.
After adjusting for variations, principally weather and billing days, firm gas sales and transportation volumes in the company’s service area increased 0.6 percent in 2012.
CECONY’s purchased gas cost decreased $131 million in 2012 compared with 2011 due to lower unit costs ($120 million) and sendout volumes ($11 million).
CECONY’s gas operating income increased $51 million in 2012 compared with 2011.
The increase reflects primarily lower operations and maintenance expense ($36 million, due primarily to a decrease in the surcharges that are collected in revenues from customers ($34 million) and higher net revenues ($25 million), offset by higher depreciation and amortization ($10 million).
