Moms Know What’s Best: How Time-of-Use Electricity Pricing can Benefit California Families

mcaf listenedCalifornia’s “big three” utilities, at the behest of state regulators, are in the process of examining and improving how they price electricity, including something called time-of-use (TOU) electricity pricing. This option – which rewards people who shift some of their electricity use to times of day when clean energy is abundant and electricity is cheaper – can help California families create safer communities while saving money on their utility bills. Mom’s Clean Air Force California mom Linda Hutchins-Knowles agrees, and recently wrote this opinion piece in the San Jose Mercury News encouraging others to adopt TOU.

Linda, like many moms, wears multiple hats. As a mother, she wants to help leave her children a safer, more sustainable word. As an advocate, she supports increasing our use of clean energy over dirty fossil fuels to help clean our air and environment as a whole. Finally, as a consumer, she wants to do these things without breaking the bank. Read More »

Information about his energy use can be accessed through mobile apps and on the web.California’s big three utilities – San Diego Gas & Electric (SDG&E), Pacific Gas & Electric (PG&E), and Southern California Edison (SCE) – serve approximately 80 percent of the state’s residential customers, which is why their recent move to update the state’s antiquated electricity pricing could be a game-changer for helping the state achieve its climate and clean energy goals.

In late December, while most people were on holiday, the utilities submitted plans to the California Public Utilities Commission (CPUC) to assess electricity prices that vary with the season and time of day. These plans detail the next two years of piloting time-of-use (TOU) pricing for most residential customers, and will help California reduce pollution and increase renewable energy production.

Four Things California Should Consider before Rolling Out Time-of-Use Pricing

twilight-532720_1280This summer the California Public Utilities Commission (CPUC) ordered big changes in how Californians will pay for electricity. Starting in 2019, residential customers of the big three investor-owned utilities (Pacific Gas & Electric, Southern California Edison, and San Diego Gas & Electric) will be switching residential customers to the same pricing plan used by commercial and industrial customers:  time-of-use (TOU) electricity pricing. This approach rewards people who shift some of their electricity use to times of the day when renewable energy is plentiful and electricity is cheaper. Before rolling this out to all 33 million Californians, however, the CPUC has instructed the utilities to perform experiments on how best to design and then market TOU pricing to customers.

These TOU pilots – which will begin summer 2016 – are the first steps in the journey toward full deployment, and as with other journeys, the first steps are often some of the most influential. Read More »

Timing is Everything: How California is Getting Electricity Pricing Right and Bringing Clean Power to the People

oilseed-rape-450155_1280Anybody managing a household budget knows it pays to plan ahead. With advanced thinking we can buy favorite items with coupons, when they’re on sale, in bulk, or at the cheapest store in the area. Similarly, we know that buying under duress, or in the touristy spot, will likely mean higher prices. Using the same smart shopper skills, new changes to the way utilities charge for electricity are going to give Californians another way to save money on energy bills.

In the current system, most California households’ electricity prices don’t change throughout the day. There is no option for lower prices when system demands are lower and electricity is cheap in wholesale markets. But that’s about to change, thanks to a recent 5-0 decision by the California Public Utilities Commission (CPUC).

Starting January 1, 2019, after a period of study, public outreach, and education, California’s large investor-owned utilities (Pacific Gas and Electric, San Diego Gas and Electric, Southern California Edison) will switch households to time-of-use (TOU) electricity pricing. Read More »

Residential Electricity Pricing in California: We Need an Overhaul, not a Tune-Up

power-poles-503935_1280Here at Environmental Defense Fund (EDF), we love win-win solutions. This is why we’re big fans of time-of-use (TOU) electricity pricing (a type of time variant electricity pricing). As I’ve written before, TOU pricing better reflects the true cost of electricity, which fluctuates throughout the day. What’s more, it brings with it significant benefits for the environment, electric reliability, and people’s wallets. By empowering customers to better control their energy bills and reduce our reliance on fossil fuels, everyone wins with TOU pricing.

Thankfully, the California Public Utilities Commission (CPUC) included TOU pricing as one of the key elements in their plan to reform residential electricity rates. But how and what Californians pay for electricity – the best way to structure rates – is currently up for debate at the CPUC.

The CPUC issued its proposed decision on restructuring California’s residential rates and moving customers to TOU rates in the new structure, which EDF strongly supports as an evolutionary leap forward. Subsequently, Commissioner Mike Florio issued an alternate proposed decision that nudges the current tiered rate system forward with a time-variation “adder.” Unfortunately, Florio’s alternate proposal amounts to more of a tune-up than the substantial overhaul required to prepare for a future grid that runs on carbon-free renewables, like wind and solar, and also powers our cars, trucks, trains, and boats.

A Dynamic Approach To California Energy Use

Californians are poised for a more functional, data-driven model for setting the prices people pay for electricity. The new model will make the massive differences in costs of providing electricity during the course of a typical day more evident to us as energy users, thereby inspiring more efficient use of electricity resources.

The California Public Utilities Commission (CPUC) started a rulemaking to examine if the current rate structure for residential energy users is fair and equitable across customer classes and if it:

  • supports statewide-energy goals;
  • facilitating technologies that enable customers to better manage their usage and bills;
  • enables conservation and efficiency on the customer side of the meter; and
  • increases the reliance on non-fossil based generation to reduce overall greenhouse gas emissions.

We know already that the short answer is “no”, so CPUC is eyeing a transition to time variant (“dynamic”) rates. According to Pacific Gas & Electric (PG&E), with time variant, or what is often referred to as “time-of-use”, pricing – rates “will be higher during summer weekday afternoons when electric demand is higher, typically noon to 6 p.m., May through October. In return you’ll pay lower rates at all other times. This means that when you use energy is just as important as how much you use.”

EDF’s Energy team has been, and will continue to be, closely involved in the CPUC’s rulemaking, which will examine several facets of the current system. EDF has also been involved in the related smart grid proceedings, such as the deployment of smart grid infrastructure – which provides the ability to both measure energy use in real time and inform customers about the costs (and environmental impacts) of their choices to use electricity at different times of the day. This Advanced Metering Infrastructure (AMI) enables a smoother transition to dynamic rates for residential consumers.

EDF is very encouraged that the CPUC is considering time variant pricing because it will help consumers to be more thoughtful about their energy usage, particularly at times when demand is peaking and pushing electricity supply sources to their limits. This type of rate structure can encourage conservation and reduce peak demand while providing customers with more choices that can ultimately lower their monthly bills. For example, allowing consumers to see how much they can save on their electric bills by reducing their energy use during peak hours will encourage a shift of energy-intensive activities, such as washing and drying clothing and dishes, to off-peak (and less expensive) times of the day.

Because a dynamic pricing system will alleviate pressure on the electric grid during peak demand, it will also lead to a more stable, less expensive energy system that is increasingly resilient to extreme weather events. The economic motivation should also help to create an easy way for consumers to make decisions more efficiently, thereby lowering their electric bills and shrinking their environmental footprints.

Futhermore, dynamic pricing can help integrate renewables and electric vehicles into the electric grid by allowing utilities to respond to price signals more effectively. For example, time-of-use rates support electric vehicle charging at times when grid resources aren’t strained, such as late at night or early in the morning when most people are sleeping.

This new approach will facilitate conservation and energy efficiency, as well as an increase in the use of clean energy sources that avoid harmful greenhouse gas and urban air pollution. If adopted, the dynamic pricing model can be a common sense approach to saving energy and money, while promoting energy efficiency and a smarter, “greener,” electric grid country-wide.
