4 Electricity Regulation Federal Power Act FERC must ensure that rates for transmission and wholesale sales of electricity in interstate commerce are just and reasonable... such Federal regulation, however, to extend only to those matters which are not subject to regulation by the States. 16 U.S.C States regulate: Generator and transmission siting, construction Distribution of electricity Retail sales of electricity Energy Policy Act of 2005 FERC must protect the reliability of the bulk electric system by enforcing mandatory reliability standards Wholesale rates and reliability Both of these key functions are affected by the EPA s Clean Power Plan 4

5 Electricity Basics Driving the turbines---- Thermal Generation Most of the electricity produced in the U.S. comes from thermal generation using heat to drive the turbines that produce electricity. Fuel Sources that heat the steam to drive the turbines Coal Natural gas Nuclear Concentrated solar (uses solar and reflective materials to generate thermal energy) Biomass 5

6 Electricity Basics Non-thermal ways to drive the turbines: Other ways to generate electricity: Wind (variable resource, often located far from load centers) Hydro Photovoltaics directly convert light to electricity (variable resource) 6

7 Different parts of the U.S. Use Different Fuel Mixes to Generate Electricity *Includes generation by agricultural waste, landfill gas recovery, municipal solid waste, wood, geothermal, non-wood waste, wind, and solar. ** Includes generation by tires, batteries, chemicals, hydrogen, pitch, purchased steam, sulfur, and miscellaneous technologies. Sum of components may not add to 100% due to independent rounding.

8 Transmission A transmission grid is a network of generating stations, transmission lines, and substations. 1. Electricity is generated and leaves the power plant 2. Its voltage is increased at a step-up substation 3. The energy travels along a transmission line to the area where the power is needed (765, 500, 345, 230 and 138 kv) 4. Once there, the voltage is decreased or stepped-down at another substation 5. A distribution power line carries the electricity 6. Electricity reaches your home or business (69, 26, 13, 4 kv, 120 V, 240 V). Demand for power is called Load How The Grid Works 8

9 Transmission Important Characteristics: Electricity is not typically stored, so supply (generation) must be produced exactly when needed to meet customer demand (load) to avoid system failure (power outage) Three types of power outages: A transient fault is a momentary loss of power typically caused by a temporary fault on a power line. Power is automatically restored once the fault is cleared. A brownout is a drop in voltage in an electrical power supply (e.g., the dimming experienced by lighting when the voltage sags). Brownouts can cause poor performance of equipment or even incorrect operation. A blackout is the total loss of power to an area and is the most severe form of power outage that can occur. Blackouts which result from or result in generators tripping are particularly difficult to recover from quickly. Outages may last from a few minutes to a few weeks. 9

10 Transmission Electricity travels at the speed of light Laws of physics dictate that power flows along path of least resistance; Limited ability to direct power along specific route Utilities must have enough generation capacity to serve their forecasted load plus some extra -- a reserve margin. Different kinds of reserves- some designed to come on line over a period of time, some designed to come on immediately (spinning or load following ). Different kinds of generators for different purposes baseload vs. peaking units Fuel security or Fuel Assurance issue FERC is investigating 10

11 Transmission Operations Pre-1990, all utilities were vertically integrated A single company generated electricity, transmitted it from the plant to load and distributed it to final consumers in a particular service territory There was little or no wholesale competition (independent generators not able to interconnect unless they were a PURPA QF) FERC regulated wholesale sales of power to customers and between companies at cost-based rates Post FERC took action to promote competition in generation and transmission FERC required transmission owners to allow non-affiliated generators to interconnect generators to the grid FERC-regulated utilities required to provide Open Access transmission service (Order No. 888) Wholesale power sellers increasingly using market based rates 11

12 RTOs and ISOs Independent System Operators (ISOs) and Regional Transmission Organizations (RTOs) were created in the late 1990s (FERC Order 2000). RTO/ISO functions include: Manage the operation of a multi-company grid for a single state (ISO) or for a region (RTO) Manage reliability of the transmission grid Operate wholesale power markets (and some other markets) Generators bid power into wholesale markets at market-based rates Least cost generators get dispatched first All generators dispatched get market clearing price bid of last generator dispatched FERC has oversight of these markets Joining an ISO or RTO is voluntary for utilities but it can help with attaining FERC approvals for mergers and market-based rate requests because joining mitigates some market power issues and can increase the relevant geographic market for market power analysis 12

14 Electric Reliability FERC has a statutory obligation to ensure the reliable operation of the bulk power system (stems from the aftermath of the 2003 blackout) Energy Policy Act of 2005 (added 215 of the Federal Power Act) requires the creation of a self regulatory electric reliability organization (ERO) that spans North America, subject to FERC oversight in the United States. The North American Electric Reliability Corporation (NERC) is the entity certified as the ERO for the U.S., Canada and the northern portion of Baja California, Mexico. Legislation required the development and enforcement of mandatory reliability standards for the bulk electric system For the past decade, the North American Electric Reliability Corporation (NERC) has been working with industry and government to implement the reliability provisions of the Act. Prior to EPAct 2005, reliability standards were voluntary, not standardized 14

15 Electric Reliability About NERC: Not for profit regulatory authority whose mission is to meet the statutory obligation to ensure the reliability of the bulk power system in North America: Jurisdiction includes users, owners, and operators of the bulk power system 100 kv and higher (e.g., generators, transmission companies, RTOs/ISOs, etc); Develops and enforces the Reliability Standards; imposes penalties for non compliance, subject to FERC approval; Ensures reliability by addressing events and identifiable risks; Annually assesses seasonal and long term reliability and provides assurance to the public, industry, and government for the reliable performance of the bulk power system; (See, e.g., Potential Reliability Impacts of EPA s Proposed Clean Power Plan, 11/5/2014, Monitors the bulk power system through system awareness; Educates, trains, and certifies industry personnel; Promotes learning and continuous improvement of operations and adapts to lessons learned for improved bulk power system reliability; Risk based Approach to focus attention, resources, and actions on issues most important to bulk power system reliability. 15

16 Electric Reliability NERC defines reliability in terms of two functional aspects: Adequacy: The ability of the electricity system to supply the aggregate electrical demand and energy requirements of the end use customers at all times, taking into account scheduled and reasonably expected unscheduled outages of system elements. Operating Reliability: The ability of the Bulk Power System to withstand sudden disturbances, such as electric short circuits or the unanticipated loss of system elements from credible contingencies, while avoiding uncontrolled cascading blackouts or damage to equipment 16

18 Reliability Reliability Standards cover broad areas: Transmission operations Vegetation management (tree trimming, ROW clearing) Cyber and physical security Communications Emergency preparedness Transmission planning, modeling, data analysis Resource and demand balancing System protection mechanisms Interchange scheduling and coordination Reliability operations Non compliance with the standards could subject a company to significant civil penalties of $1 million/day per violation. Since 2008, NERC has found nearly 6,000 standard violations and imposed millions of dollars in civil penalties for non compliance Standards applicable to all users, owners and operators of the bulk power system (facilities operating at or above 100 kv) 18

19 FERC and EPA FERC Technical Conference Issues Raised by the CPP: Electric reliability issues Retirement of coal plants - Transmission system reliability may be affected by the absence of generators in key locations (e.g., frequency control and voltage support). Reliability Must Run units have been designated in the past (also referred to as back-stop or safety valve options). Changing resource mix will result in less fuel diversity Challenges for transmission operations with integration of large amounts of Variable Energy Resources (VERs): A Variable Energy Resource is a device for the production of electricity that is characterized by an energy source that: (1) is renewable; (2) cannot be stored by the facility owner or operator; and (3) has variability that is beyond the control of the facility owner or operator, e.g., wind, solar thermal and photovoltaic, and hydrokinetic generators. See Integration of Variable Energy Resources Notice of Proposed Rulemaking, 139 FERC 61,246 (2012) Order No

20 FERC and EPA FERC Technical Conference Issues Raised by the CPP continued : New infrastructure needed to support changing resource mix Switch to natural gas requires new gas pipeline infrastructure Long lead time for siting, permitting and construction Will increase rates Increase in certain renewables will require new transmission infrastructure Long lead time for siting, permitting and construction Will increase rates Implications for FERC-administered wholesale electric power markets e.g., moving from a least-cost dispatch model to an emissions-based dispatch model Will require new RTO market rules Also likely to increase rates 20
