Supply Mix and Generation

Sign up below to receive the latest research, news, and commentary from CEI experts. For a long time, the electrical grid has dwelt quietly in the background of American life. It hums away quietly and most people seldom think about it, if at all. Recently though, this attention is shifting, as alerts to conserve electricity at peak times are becoming ever more common, especially in Texas and California.

The grid is rising to a place of cognizance. The electrical grid is a complicated and widespread machine. The following highlights some important concepts regarding the grid. Because of this need to balance power demanded with power supplied, the grid needs a relatively constant amount of power with as much consistency and predictability as possible.

Baseload units. The units that provide this reliability are referred to as baseload units or baseload plants. These units, generally nuclear power plants, coal-fired power plants, and natural gas-fired plants, provide large amounts of consistent power to the grid.

Their fuel, uranium, coal, or liquified natural gas, is managed at the facility and is therefore within the control of the plant for as long as their fuel supply lasts.

Hydroelectric dams can also be considered baseload power because operators have control of when water flows through them and can control power output in a similar manner to other baseload facilities, but they can be limited by times of drought and are only available in places with somewhat unique geography.

Intermittent sources. These are generating sources that have variability beyond the control of plant operators because their fuel comes in a different form. The most common examples of this are wind and solar facilities that rely on the wind gusting or the sun shining to provide power.

In California, there is a phenomenon where the level of solar penetration on the grid leads to a massive dip in net load the forecasted load minus intermittent sources on the grid in the middle of the day when the sun is brightest and which then drops off sharply in the early evening.

The issue is that early evening—right as many people are returning home from work—is already a time where demand on the grid increases rapidly. Solar penetration, and the resultant lowering of midday demand has exaggerated the degree of that rapid increase in the early evening.

This forces dispatchable units, those that can be called upon to produce more or less power as needed, to ramp up and down sharply. This ramping requires the dispatchable plants to come up to full power quickly, and to also stop producing quickly.

This constant cycling can be hard on equipment, and makes it difficult for the California Independent System Operator CAISO to balance supply and demand in the system. Source: Energy Information Administration. This also throws off the economics of the plants that are used for that ramping generation, because they are forced to idle for long stretches of time and then come online quickly.

It is a metric that compares the ratio between the amount of power that a unit was designed to produce, its nameplate capacity, and the amount of energy that it actually generated over that period.

So, if a facility has a nameplate capacity of 1, MW, but actually produces MW on average over a given period, it has a 90 percent capacity factor. If another unit is nameplated at 1, and only averaged MW then that unit would have a capacity factor of 20 percent.

Consistent power grid -

Both wind and solar depend on natural systems that can be modeled and forecasted with reasonable accuracy. This is especially significant because Texas has a unique isolated grid, with no way to access extra conventional electricity generation from outside the state.

In recent years, an entire industry has emerged around the practice of interpreting data from the web and other sources for the purposes of targeted advertising, political advocacy, and a variety of other practices. In the future, I believe there will be a greater need for effective renewable energy prediction, and that increasingly advanced models and algorithms to predict renewable output either an hour or day ahead of time will meet this need.

Integrating a large share of intermittent renewable energy into our daily electricity operations will require a mix of sources that complement each other to roughly equal our total energy demand over the day.

This is technically possible because continental wind energy tends to peak at night, coastal wind energy tends to peak during the day, and solar can peak at various times over the day, depending on which way it is oriented.

Accomplishing this mix will require an efficient and effective electricity market that incentivizes electricity generation at the right time and place. Existing competitive electricity markets already have prices that vary over the day and over a region depending on the local level of electricity supply and demand.

Exposing renewable energy to these prices can help encourage a mix of renewable sources that produces just the right amount of energy when we need it, and reduces the need for costly energy storage.

While the challenges posed by the intermittent nature of many renewable energy sources certainly increase the complexity of effectively operating the grid, they are far from insurmountable.

In many ways, they pale in comparison to the enormous challenges that were overcome to initially string all the wires, build all the power plants, and implement all of the controls that make up the present grid.

Minimizing the costs associated with renewable variability will be a major challenge of the coming years and decades. The views expressed are those of the author s and are not necessarily those of Scientific American.

Subscribe to Scientific American! The Challenges of Intermittent Renewable Energy The difficulty associated with integrating variable sources of electricity stems from the fact that the power grid was designed around the concept of large, controllable electric generators.

The Law of Large Numbers While at first glance it might sound like adding too much renewable energy could destabilize the delicate balance of the electric grid, it turns out that renewable energy actually becomes more predictable as the number of renewable generators connected to the grid increases thanks to the effect of geographic diversity and the Law of Large Numbers.

The Power of Prediction While the law of large numbers and the effect of geographic diversity causes renewable energy to smooth out its own fluctuations on a second-by-second basis, it can still be difficult to predict the expected level of renewable generation during the next hour or two of the day.

A Sustainable Electric Grid of the Future While the challenges posed by the intermittent nature of many renewable energy sources certainly increase the complexity of effectively operating the grid, they are far from insurmountable.

Power Markets. Get smart. In Europe one large grid connects most of continental Europe. A wide area synchronous grid also called an "interconnection" in North America is an electrical grid at a regional scale or greater that operates at a synchronized frequency and is electrically tied together during normal system conditions.

Synchronous grids with ample capacity facilitate electricity market trading across wide areas. In the ENTSO-E in , over , megawatt hours were sold per day on the European Energy Exchange EEX. Each of the interconnects in North America are run at a nominal 60 Hz, while those of Europe run at 50 Hz.

Neighbouring interconnections with the same frequency and standards can be synchronized and directly connected to form a larger interconnection, or they may share power without synchronization via high-voltage direct current power transmission lines DC ties , or with variable-frequency transformers VFTs , which permit a controlled flow of energy while also functionally isolating the independent AC frequencies of each side.

The benefits of synchronous zones include pooling of generation, resulting in lower generation costs; pooling of load, resulting in significant equalizing effects; common provisioning of reserves, resulting in cheaper primary and secondary reserve power costs; opening of the market, resulting in possibility of long-term contracts and short term power exchanges; and mutual assistance in the event of disturbances.

One disadvantage of a wide-area synchronous grid is that problems in one part can have repercussions across the whole grid. For example, in Kosovo used more power than it generated due to a dispute with Serbia , leading to the phase across the whole synchronous grid of Continental Europe lagging behind what it should have been.

The frequency dropped to This caused certain kinds of clocks to become six minutes slow. A super grid or supergrid is a wide-area transmission network that is intended to make possible the trade of high volumes of electricity across great distances.

It is sometimes also referred to as a mega grid. Super grids can support a global energy transition by smoothing local fluctuations of wind energy and solar energy. In this context they are considered as a key technology to mitigate global warming.

Super grids typically use High-voltage direct current HVDC to transmit electricity long distances. The latest generation of HVDC power lines can transmit energy with losses of only 1.

Electric utilities between regions are many times interconnected for improved economy and reliability. Electrical interconnectors allow for economies of scale, allowing energy to be purchased from large, efficient sources.

Utilities can draw power from generator reserves from a different region to ensure continuing, reliable power and diversify their loads. Interconnection also allows regions to have access to cheap bulk energy by receiving power from different sources.

For example, one region may be producing cheap hydro power during high water seasons, but in low water seasons, another area may be producing cheaper power through wind, allowing both regions to access cheaper energy sources from one another during different times of the year.

Neighboring utilities also help others to maintain the overall system frequency and also help manage tie transfers between utility regions. Electricity Interconnection Level EIL of a grid is the ratio of the total interconnector power to the grid divided by the installed production capacity of the grid.

Electricity generation is the process of generating electric power from sources of primary energy typically at power stations. Usually this is done with electromechanical generators driven by heat engines or the kinetic energy of water or wind.

Other energy sources include solar photovoltaics and geothermal power. The sum of the power outputs of generators on the grid is the production of the grid, typically measured in gigawatts GW.

Electric power transmission is the bulk movement of electrical energy from a generating site, via a web of interconnected lines, to an electrical substation , from which is connected to the distribution system.

This networked system of connections is distinct from the local wiring between high-voltage substations and customers. Because the power is often generated far from where it is consumed, the transmission system can cover great distances.

For a given amount of power, transmission efficiency is greater at higher voltages and lower currents. Therefore, voltages are stepped up at the generating station, and stepped down at local substations for distribution to customers.

Most transmission is three-phase. Three phase, compared to single phase, can deliver much more power for a given amount of wire, since the neutral and ground wires are shared. However, for conventional conductors one of the main losses are resistive losses which are a square law on current, and depend on distance.

Transmission networks are complex with redundant pathways. The physical layout is often forced by what land is available and its geology. Most transmission grids offer the reliability that more complex mesh networks provide. Redundancy allows line failures to occur and power is simply rerouted while repairs are done.

Substations may perform many different functions but usually transform voltage from low to high step up and from high to low step down. Between the generator and the final consumer, the voltage may be transformed several times.

The three main types of substations, by function, are: [26]. Distribution is the final stage in the delivery of power; it carries electricity from the transmission system to individual consumers.

Substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kV and 35 kV.

Primary distribution lines carry this medium voltage power to distribution transformers located near the customer's premises. Distribution transformers again lower the voltage to the utilization voltage. Customers demanding a much larger amount of power may be connected directly to the primary distribution level or the subtransmission level.

Distribution networks are divided into two types, radial or network. In cities and towns of North America, the grid tends to follow the classic radially fed design.

A substation receives its power from the transmission network, the power is stepped down with a transformer and sent to a bus from which feeders fan out in all directions across the countryside. These feeders carry three-phase power, and tend to follow the major streets near the substation.

As the distance from the substation grows, the fanout continues as smaller laterals spread out to cover areas missed by the feeders. This tree-like structure grows outward from the substation, but for reliability reasons, usually contains at least one unused backup connection to a nearby substation.

This connection can be enabled in case of an emergency, so that a portion of a substation's service territory can be alternatively fed by another substation. Grid energy storage also called large-scale energy storage is a collection of methods used for energy storage on a large scale within an electrical power grid.

Electrical energy is stored during times when electricity is plentiful and inexpensive especially from intermittent power sources such as renewable electricity from wind power , tidal power and solar power or when demand is low, and later returned to the grid when demand is high, and electricity prices tend to be higher.

As of [update] , the largest form of grid energy storage is dammed hydroelectricity , with both conventional hydroelectric generation as well as pumped storage hydroelectricity.

Developments in battery storage have enabled commercially viable projects to store energy during peak production and release during peak demand, and for use when production unexpectedly falls giving time for slower responding resources to be brought online.

Two alternatives to grid storage are the use of peaking power plants to fill in supply gaps and demand response to shift load to other times.

The demand, or load on an electrical grid is the total electrical power being removed by the users of the grid. Baseload is the minimum load on the grid over any given period, peak demand is the maximum load.

Historically, baseload was commonly met by equipment that was relatively cheap to run, that ran continuously for weeks or months at a time, but globally this is becoming less common. The extra peak demand requirements are sometimes produced by expensive peaking plants that are generators optimised to come on-line quickly but these too are becoming less common.

However, if the demand of electricity exceed the capacity of a local power grid, it will cause safety issue like burning out. Grids are designed to supply electricity to their customers at largely constant voltages.

This has to be achieved with varying demand, variable reactive loads, and even nonlinear loads, with electricity provided by generators and distribution and transmission equipment that are not perfectly reliable.

In a synchronous grid all the generators must run at the same frequency, and must stay very nearly in phase with each other and the grid.

Generation and consumption must be balanced across the entire grid, because energy is consumed as it is produced. For rotating generators, a local governor regulates the driving torque, maintaining almost constant rotation speed as loading changes.

Energy is stored in the immediate short term by the rotational kinetic energy of the generators. Although the speed is kept largely constant, small deviations from the nominal system frequency are very important in regulating individual generators and are used as a way of assessing the equilibrium of the grid as a whole.

When the grid is lightly loaded the grid frequency runs above the nominal frequency, and this is taken as an indication by Automatic Generation Control systems across the network that generators should reduce their output. Conversely, when the grid is heavily loaded, the frequency naturally slows, and governors adjust their generators so that more power is output droop speed control.

When generators have identical droop speed control settings it ensures that multiple parallel generators with the same settings share load in proportion to their rating.

In addition, there's often central control, which can change the parameters of the AGC systems over timescales of a minute or longer to further adjust the regional network flows and the operating frequency of the grid.

For timekeeping purposes, the nominal frequency will be allowed to vary in the short term, but is adjusted to prevent line-operated clocks from gaining or losing significant time over the course of a whole 24 hour period. An entire synchronous grid runs at the same frequency, neighbouring grids would not be synchronised even if they run at the same nominal frequency.

High-voltage direct current lines or variable-frequency transformers can be used to connect two alternating current interconnection networks which are not synchronized with each other.

This provides the benefit of interconnection without the need to synchronize an even wider area. For example, compare the wide area synchronous grid map of Europe with the map of HVDC lines.

The sum of the maximum power outputs nameplate capacity of the generators attached to an electrical grid might be considered to be the capacity of the grid. However, in practice, they are never run flat out simultaneously. Typically, some generators are kept running at lower output powers spinning reserve to deal with failures as well as variation in demand.

In addition generators can be off-line for maintenance or other reasons, such as availability of energy inputs fuel, water, wind, sun etc. or pollution constraints. Firm capacity is the maximum power output on a grid that is immediately available over a given time period, and is a far more useful figure.

Most grid codes specify that the load is shared between the generators in merit order according to their marginal cost i. cheapest first and sometimes their environmental impact. Thus cheap electricity providers tend to be run flat out almost all the time, and the more expensive producers are only run when necessary.

Failures are usually associated with generators or power transmission lines tripping circuit breakers due to faults leading to a loss of generation capacity for customers, or excess demand. This will often cause the frequency to reduce, and the remaining generators will react and together attempt to stabilize above the minimum.

If that is not possible then a number of scenarios can occur. A large failure in one part of the grid — unless quickly compensated for — can cause current to re-route itself to flow from the remaining generators to consumers over transmission lines of insufficient capacity, causing further failures.

One downside to a widely connected grid is thus the possibility of cascading failure and widespread power outage. A central authority is usually designated to facilitate communication and develop protocols to maintain a stable grid.

For example, the North American Electric Reliability Corporation gained binding powers in the United States in , and has advisory powers in the applicable parts of Canada and Mexico. The U. government has also designated National Interest Electric Transmission Corridors , where it believes transmission bottlenecks have developed.

A brownout is an intentional or unintentional drop in voltage in an electrical power supply system. Intentional brownouts are used for load reduction in an emergency. The term brownout comes from the dimming experienced by incandescent lighting when the voltage sags. A voltage reduction may be an effect of disruption of an electrical grid, or may occasionally be imposed in an effort to reduce load and prevent a power outage , known as a blackout.

A power outage also called a power cut , a power out , a power blackout , power failure or a blackout is a loss of the electric power to a particular area.

Power failures can be caused by faults at power stations, damage to electric transmission lines, substations or other parts of the distribution system, a short circuit , cascading failure , fuse or circuit breaker operation, and human error. Power failures are particularly critical at sites where the environment and public safety are at risk.

Institutions such as hospitals , sewage treatment plants, mines , shelters and the like will usually have backup power sources such as standby generators , which will automatically start up when electrical power is lost.

Other critical systems, such as telecommunication , are also required to have emergency power. The battery room of a telephone exchange usually has arrays of lead—acid batteries for backup and also a socket for connecting a generator during extended periods of outage.

Electrical generation and transmission systems may not always meet peak demand requirements— the greatest amount of electricity required by all utility customers within a given region. In these situations, overall demand must be lowered, either by turning off service to some devices or cutting back the supply voltage brownouts , in order to prevent uncontrolled service disruptions such as power outages widespread blackouts or equipment damage.

Utilities may impose load shedding on service areas via targeted blackouts, rolling blackouts or by agreements with specific high-use industrial consumers to turn off equipment at times of system-wide peak demand.

A black start is the process of restoring an electric power station or a part of an electric grid to operation without relying on the external electric power transmission network to recover from a total or partial shutdown.

Normally, the electric power used within the plant is provided from the station's own generators. If all of the plant's main generators are shut down, station service power is provided by drawing power from the grid through the plant's transmission line. However, during a wide-area outage, off-site power from the grid is not available.

In the absence of grid power, a so-called black start needs to be performed to bootstrap the power grid into operation. To provide a black start, some power stations have small diesel generators , normally called the black start diesel generator BSDG , which can be used to start larger generators of several megawatts capacity , which in turn can be used to start the main power station generators.

It is uneconomical to provide such a large standby capacity at each station, so black-start power must be provided over designated tie lines from another station. Often hydroelectric power plants are designated as the black-start sources to restore network interconnections.

A hydroelectric station needs very little initial power to start just enough to open the intake gates and provide excitation current to the generator field coils , and can put a large block of power on line very quickly to allow start-up of fossil-fuel or nuclear stations.

Certain types of combustion turbine can be configured for black start, providing another option in places without suitable hydroelectric plants. Despite the novel institutional arrangements and network designs of the electrical grid, its power delivery infrastructures suffer aging across the developed world.

Contributing factors to the current state of the electric grid and its consequences include:. Demand response is a grid management technique where retail or wholesale customers are requested or incentivised either electronically or manually to reduce their load.

Currently, transmission grid operators use demand response to request load reduction from major energy users such as industrial plants. With everything interconnected, and open competition occurring in a free market economy , it starts to make sense to allow and even encourage distributed generation DG.

Smaller generators, usually not owned by the utility, can be brought on-line to help supply the need for power. The smaller generation facility might be a home-owner with excess power from their solar panel or wind turbine.

It might be a small office with a diesel generator. These resources can be brought on-line either at the utility's behest, or by owner of the generation in an effort to sell electricity.

Many small generators are allowed to sell electricity back to the grid for the same price they would pay to buy it. As the 21st century progresses, the electric utility industry seeks to take advantage of novel approaches to meet growing energy demand.

Utilities are under pressure to evolve their classic topologies to accommodate distributed generation. As generation becomes more common from rooftop solar and wind generators, the differences between distribution and transmission grids will continue to blur.

In July the CEO of Mercedes-Benz said that the energy industry needs to work better with companies from other industries to form a "total ecosystem", to integrate central and distributed energy resources DER to give customers what they want.

The electrical grid was originally constructed so that electricity would flow from power providers to consumers. However, with the introduction of DER, power needs to flow both ways on the electric grid, because customers may have power sources such as solar panels. The smart grid is an enhancement of the 20th century electrical grid, using two-way communications and distributed so-called intelligent devices.

Two-way flows of electricity and information could improve the delivery network. Research is mainly focused on three systems of a smart grid — the infrastructure system, the management system, and the protection system. The smart grid represents the full suite of current and proposed responses to the challenges of electricity supply.

Numerous contributions to the overall improvement of the efficiency of energy infrastructure are anticipated from the deployment of smart grid technology, in particular including demand-side management. The improved flexibility of the smart grid permits greater penetration of highly variable renewable energy sources such as solar power and wind power , even without the addition of energy storage.

Concerns with smart grid technology mostly focus on smart meters, items enabled by them, and general security issues. Roll-out of smart grid technology also implies a fundamental re-engineering of the electricity services industry, although typical usage of the term is focused on the technical infrastructure.

As there is some resistance in the electric utility sector to the concepts of distributed generation with various renewable energy sources and microscale cogen units, several authors have warned that mass-scale grid defection [ definition needed ] is possible because consumers can produce electricity using off grid systems primarily made up of solar photovoltaic technology.

The Rocky Mountain Institute has proposed that there may be widescale grid defection. Early electric energy was produced near the device or service requiring that energy. In the s, electricity competed with steam, hydraulics, and especially coal gas. Coal gas was first produced on customer's premises but later evolved into gasification plants that enjoyed economies of scale.

In the industrialized world, cities had networks of piped gas, used for lighting. But gas lamps produced poor light, wasted heat, made rooms hot and smokey, and gave off hydrogen and carbon monoxide. They also posed a fire hazard.

In the s electric lighting soon became advantageous compared to gas lighting. Electric utility companies established central stations to take advantage of economies of scale and moved to centralized power generation, distribution, and system management.

Historically, transmission and distribution lines were owned by the same company, but starting in the s, many countries have liberalized the regulation of the electricity market in ways that have led to the separation of the electricity transmission business from the distribution business.

The bill was the first step towards an integrated electricity system. The Electricity Supply Act led to the setting up of the National Grid. This started operating as a national system, the National Grid , in In France, electrification began in the s, with communes in , and 36, in At the same time, these close networks began to interconnect: Paris in at 12 kV, the Pyrénées in at kV, and finally almost all of the country interconnected by at kV.

In , the grid was the world's most dense. That year the state nationalised the industry, by uniting the private companies as Électricité de France. The frequency was standardised at 50 Hz, and the kV network replaced kV and kV. During the s, the kV network, the new European standard, was implemented.

In the United States in the s, utilities formed joint-operations to share peak load coverage and backup power. In , with the passage of the Public Utility Holding Company Act USA , electric utilities were recognized as public goods of importance and were given outlined restrictions and regulatory oversight of their operations.

The Energy Policy Act of required transmission line owners to allow electric generation companies open access to their network [55] [62] and led to a restructuring of how the electric industry operated in an effort to create competition in power generation.

No longer were electric utilities built as vertical monopolies, where generation, transmission and distribution were handled by a single company. Now, the three stages could be split among various companies, in an effort to provide fair access to high voltage transmission. In China, electrification began in the s.

In , it completed the power supply project of China's important electrified railways in its operating areas, such as Jingtong Railway , Haoji Railway , Zhengzhou—Wanzhou high-speed railway , et cetera, providing power supply guarantee for traction stations, and its cumulative power line construction length reached 6, kilometres.

This is the capacity of resources that are connected directly to the high-voltage provincial grid, which is controlled by the IESO.

Typically, these are industrial-scale power plants and wind and solar farms that can produce large amounts of electricity. Transmission-Connected Capacity as of December Source: Reliability Outlook. This is the capacity of resources that are connected to a low-voltage community grid, which is controlled by your local hydro company.

Typically, these are small-scale generators, demand response resources or energy storage that are owned and maintained by individuals, local facilities or other businesses.

These resources serve some, or all, of the energy needs of their owners, reducing demand on the provincial grid. Distribution-Connected Capacity as of July Source: Progress Report on Contracted Electricity Supply.

While capacity represents the maximum amount of electricity that the system can supply at any given time, the actual amount of energy produced varies.

Most of the electricity produced in Ontario is generated at nuclear and hydro plants, which produce low levels of greenhouse gas emissions.

Total Electricity Output by Source in Source: Year End Data. Hydroelectricity is generated by falling or moving water. Hydro is particularly valuable as an energy resource because it is clean, renewable and serves as a source of baseload, intermediate and peaking generation. It is a primary supplier of long-term, emissions-free, baseload electricity generation.

Natural gas is a very flexible form of electricity generation that can increase or decrease output within minutes to meet sudden or unexpected changes in supply and demand. The amount of energy wind turbines produce depends on the weather.

Wind tends to produce the most during cold months in the winter, spring and fall and their output varies based on geography. The amount of energy solar panels produce depends on the weather. Solar is particularly valuable in the summer months on hot, sunny days, helping to off-set increased air conditioning use, which reduces strain on the electricity grid.

Biofuel is a clean and renewable source of energy. Ontario has many sources of biofuel, such as residual materials from forestry, waste matter from agriculture, by-products from food processing and waste from municipal landfills, compost and water treatment facilities.

One of the most significant changes to electricity systems around the world has been the emergence of new technologies that can support locally-owned facilities for electricity generation and storage.
