Business description of Talen-Energy-Corporation from last 10-k form

GENERAL
Capitalized terms and abbreviations are defined in the glossary. Dollars are in millions, unless otherwise noted.
Talen Energy Corporation, through its principal subsidiary Talen Energy Supply, is a North American competitive energy and power generation and marketing company headquartered in Allentown, Pennsylvania. Talen Energy produces and sells electricity, capacity and ancillary services from its fleet of power plants totaling approximately 17,400 MW of generating capacity. Talen Energy's portfolio of generation assets is principally located in the Northeast, Mid-Atlantic and Southwest regions of the U.S. See "Item 2. Properties" for additional information on Talen Energy's plants.
Talen Energy's business was formed on June 1, 2015 by the spinoff of Talen Energy Supply, the competitive power generation business owned by PPL, and the substantially contemporaneous combination of that business with RJS Power, the competitive power generation business controlled by Riverstone Holdings LLC, under a new holding company, Talen Energy Corporation. See Notes 1, 3 and 6 to the Financial Statements for additional information on the spinoff and acquisition.
Talen Energy seeks to optimize the value from its competitive power generation assets and marketing portfolio while mitigating near-term volatility in both cash flow and earnings metrics. Talen Energy endeavors to accomplish this by matching projected output from its generation assets with forward power sales in the wholesale and retail markets while effectively managing exposure to fuel price volatility, counterparty credit risk and operational risk. Talen Energy is focused on safe, reliable, and resilient operations, disciplined capital investment, portfolio optimization, cost management and the pursuit of value-enhancing growth opportunities.
To manage financing costs and access to credit markets, and to fund capital expenditures and growth opportunities, a key objective of Talen Energy is to maintain adequate liquidity capacity. In addition, Talen Energy has a financial risk management policy and operational procedures that, among other things, are designed to monitor and manage exposure to earnings and cash flow volatility related to, as applicable, changes in energy and fuel prices, interest rates, counterparty credit quality and the operating performance of generating units. To manage these risks, Talen Energy generally uses contracts such as forwards, options, swaps and insurance contracts primarily focused on mitigating cash flow volatility within the next 12 month period.
The following chart illustrates Talen Energy's organizational structure as of December 31, 2015.
Talen Energy's subsidiaries, Talen Generation, Raven, Jade, Sapphire, and MACH Gen, own and operate competitive power generation facilities. Another Talen Energy subsidiary, Talen Energy Marketing, markets the output of Talen Energy's plants, electricity, capacity and ancillary services, and other energy-related products in competitive wholesale and retail markets.

Talen Energy Marketing sells the output of its affiliated generation facilities to a diverse group of wholesale customers, including RTOs and ISOs, utilities, cooperatives, municipalities, power marketers, and financial counterparties. Talen Energy Marketing also sells the output of its affiliated generation plants to commercial, industrial and residential retail customers.
Talen Energy earns revenue primarily by participating in energy and capacity markets and by providing related ancillary services.
Talen Energy's generation fleet is diverse in terms of fuel, technology, dispatch characteristics and location. A majority of Talen Energy's revenue comes from the sale of electricity produced by its generation facilities. Talen Energy also produces additional revenue from the sale of capacity within the PJM, ISO-NE and NYISO markets as well as by providing ancillary services.
The charts below illustrate the composition and diversity of Talen Energy's generation portfolio capacity (summer rating) by market and fuel type as of December 31, 2015:
The charts above do not reflect the completed or announced divestitures of approximately 1,400 MW of generation capacity to satisfy the FERC approved mitigation in connection with the RJS Power acquisition. See "Acquisitions and Divestitures" below and Notes 1 and 6 to the Financial Statements for additional information.

Recent Market Developments
As a result of unusual market and weather volatility in the first quarter of 2014, PJM determined that changes were necessary to ensure system reliability. In December 2014, PJM proposed to add an enhanced Capacity Performance (CP) product to the capacity market structure to permit additional compensation for generation owners/operators to make the necessary investments to maintain system reliability in exchange for stronger performance requirements, with higher penalties for non-performers. For more information on recent PJM market developments, see "Item 7. Combined Management's Discussion and Analysis of Financial Condition and Results of Operations" for additional information.
The PUCT and ERCOT have taken significant measures to improve scarcity pricing in ERCOT.  ERCOT's system-wide offer cap was increased from $7,000 per MWh to $9,000 per MWh effective June 1, 2015.  An operating reserve demand curve (ORDC) was implemented in June 2014, which is intended to produce longer periods of gradually increasing scarcity prices, and the PUCT and ERCOT are currently evaluating whether any changes need to be made to improve the operation of the ORDC during scarcity conditions.
The NYISO will be undertaking its triennial Demand Curve Reset (DCR) process, which will reset the capacity auction parameters, potentially impacting compensation to capacity resources. Draft tariff sheets reflecting recommended changes to the DCR process are to be presented to the NYISO's Installed Capacity Working Group in February 2016.
Two major initiatives, Reform the Energy Vision and the Clean Energy Standard are being pursued in New York State. Both of these initiatives are long term endeavors and either or both could have impacts on the overall New York energy market. Talen Energy is still assessing any potential impacts to both the market and its portfolio.
ISO-NE added an enhanced Performance Incentive (PI) product to the capacity market structure to permit additional compensation for generation owners/operators to make the necessary investments to maintain system reliability in exchange for stronger performance requirement, with higher penalties for non-performers without exception. The PI product was first implemented in the ninth forward capacity auction for delivery year 2018/19, which was held in February 2015. ISO-NE merged the Northeast Massachusetts zone with the Southeastern Massachusetts/Rhode Island capacity zone to create the import-constrained Southern New England (SENE) zone. The tenth forward capacity auction will now only consist of two zones: SENE and Rest of Pool (including Maine, Western/Central Massachusetts, New Hampshire and Vermont). In addition,
ISO-NE has unveiled a new, sloped demand curve design that could be implemented for the eleventh forward capacity auction and would likely put downward pressure on clearing prices.
RESERVE MARGINS
Reserve margin is a measure of generation capacity available to meet peak demand. Each ISO/RTO sets a target reserve margin to ensure grid reliability, which is used as an indicator of a supply surplus or deficit based on the requirement. If the actual reserve margin exceeds the requirement, the system is in a surplus and energy prices should remain lower and stable. A deficit to the required reserve margin could trigger energy price spikes and volatility, sending a signal to the market that more capacity is needed. PJM, NYISO, and ISO-NE have forward looking capacity markets to procure sufficient capacity to meet forecasted demand. ERCOT operates in an energy only market, where scarcity pricing sends the signal to develop more capacity. Each market is currently well supplied and reserve margins exceed their targets and low energy prices are reflective of the adequate reserves. The table below contains the target reserve margin and the expected reserve margin for the 2015/16 planning year for each of the aforementioned ISOs/RTOs:
