1 July 15, 2013 Flexible Capacity Planning for Renewable Integration CEF Topical White Paper Jeremy Hargreaves, Elaine Hart, Ryan Jones, Arne Olson E3 Problem Statement For California, meeting an economy- wide 2050 goal of reducing GHG emissions 80% below 1990 levels will require reducing electricity generation emissions intensities to less than kg CO 2 /kwh while doubling generation to TWh/year [1]. The California electricity system is on course to radically change in the coming decades, both in physical assets and in system operations. In order to meet these challenges sustainably, California faces the planning problem of transforming its electricity system technologically while maintaining reliability and keeping the cost to ratepayers as low as possible. California has already made a strong commitment to a generation mix with a large share of renewable energy, with a 33% target in 2020 (not counting behind- the- meter renewables), and with higher targets already being discussed for The main renewable generation resources being procured by California utilities, solar and wind, are intermittent and non- dispatchable. These attributes increase the variability of the net load (i.e., load minus renewable generation) served by the conventional thermal generation system. That system was traditionally composed of dispatchable, highly reliable thermal units (mostly natural gas) combined with hydroelectric resources that are dispatchable within well- understood constraints. Load also varies over time, being correlated to weather patterns and time of day, week, and year, and to customer behavior. As long as sufficient capacity was reliably available on to meet peak load, sufficient system flexibility was assumed to be available to meet load intermittency. This situation has changed dramatically. Following the implementation of RPS procurement policies, today over 20% of generation in California comes from intermittent renewable resources, and the number is steadily increasing. Adding these new resources to the system over just a few years has caused supply growth to outstrip load growth. At the current time, thermal resources sit above renewables in the loading order meaning that renewable generation is preferentially accepted by the system resulting in lower thermal system utilization and consequently higher levels of thermal system flexibility. However, future load growth and continued additions of renewables will eventually lead to the need for new flexible capacity in order to meet the increased net load ramps (MW/hour or MW/min) imposed by a more highly renewable system. Flexibility is the degree to which the system can respond to changes in system net load, defined over varying time scales. Figure 1 below shows conceptually the magnitude and response times of different forms of flexible capacity. On very short time scales, for example, frequency control may be provided by

2 generation dispatch, or by governor response or AGC, or by energy storage, or by stored mechanical inertia. Over time scales of an hour or longer, thermal units can be started up to meet load. The response times of different types of supply are shown. Figure 1: Flexibility conceptual representation (Russ Philbrick, PES General Meeting, Detroit, July 2011) Figure 2 below shows a simulated operating day for California that illustrates four types of flexibility challenges that the system will face under high renewable penetration. The chart shows the types of resources that are operating during each hour. The four challenges are numbered on the chart: 1. Downward ramping capability: Thermal resources operating to serve loads at night must be ramped downward to make room for a significant influx of solar energy after 8:00 AM. 2. Minimum generation flexibility: Overgeneration may occur during hours with high renewable production even if thermal resources and imports are reduced to their minimum levels. A system with more flexibility to reduce thermal generation will produce less overgeneration. 3. Upward ramping capability: Thermal resources must ramp up quickly from minimum levels during the daytime hours to meet a high net peak demand that occurs shortly after sundown. If the system cannot ramp quickly enough, load shedding may result. 4. Peaking capability: The system will continue to need enough resources to meet the highest peak loads with sufficient reliability. 2

3 Figure 2: Simulated operating day on the California system As renewable penetration increases, the ramping events in the morning and evening will become steeper and larger. In addition, the minimum load that the thermal system has to serve becomes smaller. The thermal system has to provide steeper, more prolonged ramping in both the downward and upward direction, as well as meeting lower minimum net loads, as the penetration of renewables increases and load grows. California s existing system of thermal and hydro resources is limited in how much flexibility it can provide. At some renewable penetration level, the existing system will be unable to meet net load, resulting in reduced reliability. This can manifest in either load shedding or overgeneration, depending on the direction of the violation and the way that the system is operated. This situation requires development of a new electricity planning paradigm. Traditionally, capacity planning has ensured that the system peak load can be met using available resources with a 1 day in 10 years probability of outage. Flexibility requirements to serve net load fluctuations were implicitly met by the conventional system of thermal and hydro resources. The ability of the system to meet ramping needs was studied separately or else simply assumed. As the penetration of intermittent resources increases, however, ramp requirements must be subjected to more rigorous study. Flexibility must be explicitly planned for to ensure that higher net load ramp demands are met. The new planning paradigm must consider not only the peak capacity and reliability of resources, but also their ramping rates and operating ranges. What used to require only a forecast of expected system peak load now needs to consider a broad range of system operations questions as well. The basic 3

4 planning question for systems with high penetrations of intermittent resources is now how can system capacity and flexibility needs be reliably met while keeping rate impacts as low as possible? The resulting least cost portfolio of capacity and flexibility solutions may include physical assets, and may also be met with operational strategies. Physical assets include flexible generation, energy storage, and transmission. Operational strategies include demand response, improved forecasting, market design, and curtailment of renewable resources, for example. In switching the planning paradigm to a focus on flexibility, all options are on the table. Literature Review Least cost system planning for both capacity and flexibility under high renewable penetrations has yet to be fully developed in the literature or in industry practice. The integration problem, however, has been well established in numerous studies, as summarized by Smith et al. [2]. Regional studies have been typical in the past few years for system operators facing the coming challenge of integrating significant amounts of renewables. For example, in California the system operator developed a methodology to assess integration issues for a 20% RPS, finding that thermal resources may not always be sufficiently flexible at low loads and recommending a reduction in self scheduling [3]. NREL s western wind and solar integration study examined the needs of the western states and concluded 35% penetration of renewables was possible with increased balancing area cooperation, improved day- ahead forecasting, and sub- hourly scheduling [4]. However these studies made only general recommendations, did not trade off flexibility solutions under an economic framework to determine the least cost portfolio, and did not consider all flexibility options. They are not substitutes for a rigorous resource planning process. Lannoye et al. made some headway in defining metrics by which to judge flexibility needs [5]. Analogous to loss of load probability (LOLP) and effective load carrying capability (ELCC) used in traditional capacity planning, they proposed inadequate ramp resource probability (IRRP) and effective ramping capability (ERC). However unlike traditional capacity planning, there are no accepted standards for reliability to determine how flexible the system needs to be. The existing capacity reliability standard of 1- in- 10 is a generally accepted holdover from the early years of grid planning, implicitly valuing the level of reliability customers are willing to accept. This implicit value can be an order of magnitude or higher than the value of lost load (VOLL) from customer surveys [6]. Rather than determine a new flexibility reliability standard, our work assumes that the shift in planning paradigm should be accompanied by explicit consideration of the societal cost of system failures, balancing gains in system reliability against the cost of the measures taken to achieve them. Current Work Planning to meet the capacity and flexibility needs of the electric system for future high renewable penetrations is a complex, stochastic problem that is computationally intensive and must be made tractable for solution on today s computing resources through a series of simplifications. One approach is the REFLEX model developed by E3, which seeks to balance useful evaluation of portfolio solutions with efficient computation. 4

5 Joint capacity and flexibility planning is far more complex that planning for capacity alone. Generating capacity has, in the past, been the only solution to meeting increasing peak load. However, the joint planning problem may be solved by any of several different flexibility and capacity solutions. These fall generally into two categories. First are physical solutions, including: Fast- ramping conventional resources such as aeroderivative combustion turbines (CTs) or internal combustion engines (ICEs) Energy storage resources such as batteries, flywheels, or pumped hydroelectric storage A geographically- and technologically- diverse portfolio of renewable resources Transmission to improve access to flexible resources Second are solutions that involve operating the system differently: Customer- side resources such as responsive demand, load shifting or electric vehicle charging Interregional coordination to achieve load and resource diversity and make better use of latent flexibility from existing resources Compensated curtailment of renewable resources Improvements in forecasting of renewable generation in day ahead and hour ahead markets Restructuring of electricity market to include additional market windows between the day ahead and hour ahead These solutions have very different investment cost and operating characteristics; some solutions are relatively inexpensive but more limited in their ability to prevent flexibility violations, while others such as storage are more expensive but provide more flexible operations. A framework is needed to investigate the cost- effectiveness of these solutions in mitigating flexibility challenges, considering both their costs and their operating benefits. The most likely least- cost plan for high penetration renewables will involve a portfolio of different flexibility and capacity solutions. In many cases, operational characteristics other than maximum capacity are key elements of a flexibility solution. Any model to determine the least cost portfolio must therefore consider future operations while robustly representing the statistical measures of system reliability. Such a model must be stochastic, while capturing system operations. For the California system, fully capturing operations would make the problem intractable using today s computing resources. A series of simplifications must be made to solve the model while still adequately representing the system and the behavior of potential flexibility solutions. To bridge the gap between current integration studies and planning for future integration solutions, E3 developed the REFLEX model to find the least- cost flexibility portfolio. REFLEX simplifies the problem stated above while maintaining a useful system representation. The model was designed to inform decision- makers about the relative value of alternative solutions and the interactions among them, and identifying a technology pathway for achieving high penetrations of renewable energy. REFLEX is a stochastic production simulation model that characterizes the expected frequency, magnitude, and duration of flexibility shortages such as Expected Unserved Energy (EUE), Expected Unserved Ramp 5

6 (EUR) and Expected Overgeneration (EOG). Cost penalties are assigned to each violation, and REFLEX calculates the total operational cost including fuel and O&M costs, the cost of emissions allowances, and the cost of flexibility violations. Solutions are compared based on their ability to reduce flexibility violations relative to a benchmark case without the solution, and secondarily for their ability to reduce fuel costs, O&M costs, and emissions allowance costs. Solutions can be introduced sequentially or in combination. Cost- effectiveness can be determined by comparing these benefits to the cost of the solution. These outputs allow the identification of economically- optimal flexible capacity investments. The model develops a robust estimate of the expected cost of insufficient flexibility by sampling a broad range of potential future operating conditions. Cost penalties are based on the value of lost load (for upward violations) or the cost of procuring additional renewable energy (for downward violations). These costs can then be weighed against the cost of investments in new flexible capacity. The optimal investment plan minimizes the sum of operating costs, annualized fixed costs, and flexibility shortage costs. This process is illustrated in Figure 3 below. The area under the curve represents the total cost of serving load during a year, which includes fixed costs, operating costs such as fuel and O&M costs, and the cost of flexibility violations. If a system is highly inflexible, it may encounter significant flexibility violations under high renewables including lost load, overgeneration, and ramping shortages. As more flexibility is added (moving to the right along the X- axis), flexibility violations are reduced. However, the costs of investments in new flexible resources such as CTs or energy storage are also added. A cost minimization point can be found by adding new flexible resources until the marginal value of avoided flexibility violations is equal to the marginal cost of the next flexible resource added. 6

7 Figure 3: Total system cost curve with added flexible capacity The simple example in Figure 3 considers only combustion turbines as a solution to flexibility. However REFLEX can evaluate the relative cost effectiveness of any flexibility solution. The least- cost portfolio of solutions can be identified from a set of options. REFLEX enables production simulation modeling to be conducted for a broad range of system conditions including 1- in- 10 year load and hydro conditions, as well as the full range of renewable resource outputs down to very fine time- steps. Future Research Needs The simplifications used in the development of the REFLEX mode to be efficient computationally include the following, which impose the limitations described: 1. Reducing the number of simulations: may restrict the model s ability to find the most challenging operating problems and identify the optimal solutions 2. Limiting the time- step to 5 minutes: reduces the suitability of the analysis for evaluation of very fast- ramping resources such as battery storage 3. Modeling of California as an electrical island with imports and exports consistent with historical usage on the interties: may produce conservative estimates of the effectiveness of future markets to solve flexibility needs 4. Simplifying the operating characteristics of flexible resources such as thermal generator heat rate curves and representation of the units during start- up and shut- down conditions: may reduce the accuracy of these representations 5. Ignoring transmission constraints within each study area: may restrict the model s ability to identify flexibility issues within local areas Further REFLEX model development work will include shifting the model towards more complex representations of the system for each of these five simplifications while maintaining practical 7

8 computational efficiency. Preliminary model results suggest that switching to a zonal transmission model of California would be of particular benefit. California faces key flexibility challenges within different transmission zones in the coming decade with the loss of the San Onofre Nuclear Generating Station and the retirements of coastal once through cooling power plants. Both capacity and flexibility in the LA Basin may be compromised as a result. We believe REFLEX combined with a zonal transmission model is well suited to quantifying the need in the LA Basin for both capacity and flexibility resources, and identifying the least cost portfolio of solutions. This is a critical research question for California going forward, as the response to the SONGS shutdown and OTC retirements potentially substantially affects reliability, cost, and emissions of the electricity system.
