(Check out our <a href=\"https:\/\/aurorasolar.com\/blog\/how-time-of-use-rates-work\/\">older blog post<\/a> for a refresher on TOU rates). As of January 2023, the available electric rates are: E-ELEC for PG&amp;E customers, TOU-D-PRIME for SCE customers, and EV-TOU-5 for SDG&amp;E customers. Compared with the regular TOU rates, these electrification rates have:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Notably higher on-peak charges and lower off-peak charges<\/li>\n\n\n\n<li>A fixed charge of $15 per month rather than a minimum fee of $10<\/li>\n\n\n\n<li>They still share a peak rate period of 4pm &#8211; 9pm<\/li>\n<\/ul>\n\n\n\n<p>In addition, NBT customers are billed monthly rather than annually like in NEM 2.0.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-export-rates\">Export rates<\/h3>\n\n\n\n<p>Export compensation in NEM 3.0 is based on California\u2019s Avoided Cost Calculator (ACC), with a specific export rate for every combination Month, Hour, and Weekday or Weekend. For example, August weekdays from 3 &#8211; 4pm will have one value, 4 &#8211; 5pm will have a different value, and so on. The export value is lowest in the middle of the day when the grid has plentiful solar energy, and is highest during peak summer demand periods. The heatmap below shows the rates for SDG&amp;E weekdays throughout the year \u2014 compensation exceeds retail rate only during August, September, and October late afternoon hours.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"546\" src=\"https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-1-1024x546.jpg\" alt=\"\" class=\"wp-image-7566\" srcset=\"https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-1-1024x546.jpg 1024w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-1-300x160.jpg 300w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-1-768x410.jpg 768w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-1-320x171.jpg 320w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-1-816x435.jpg 816w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-1-896x478.jpg 896w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-1-448x239.jpg 448w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-1-508x271.jpg 508w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-1-100x53.jpg 100w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-1-740x395.jpg 740w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-1.jpg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>To compare the TOU rates against the ACC export rates, let\u2019s look just at the month of August.

To try to keep solar PV systems financially viable for homeowners, customers in PG&amp;E and SCE service territories also receive an adder on top of the ACC rate, between 2.2 and 9 cents depending on location and customer class.<\/p>\n\n\n\n<p>If you want to learn a bit about why electricity is so expensive from 4pm &#8211; 7pm, check out our blog post on the \u201c<a href=\"https:\/\/aurorasolar.com\/blog\/the-duck-curve-a-review-of-californias-daily-load-predictions\/\">duck curve<\/a>\u201d.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">The calculation process<\/h3>\n\n\n\n<p>How do you calculate utility bills with NEM 3.0? It\u2019s a little more complicated, but we will break it down here. To start, you need to have an hourly load profile and hourly PV production estimation. Aurora provides methods for you to <a href=\"https:\/\/aurorasolar.com\/blog\/how-to-estimate-a-homeowners-energy-load-profile\/\">estimate<\/a> or upload a customer\u2019s hourly load profile, and use our design tool and <a href=\"https:\/\/help.aurorasolar.com\/hc\/en-us\/articles\/220132468-Aurora-Simulation-Engine\">PV simulator<\/a> to get all of this information<\/p>\n\n\n\n<p>The calculation follows these steps:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>For every hour, look at the customer\u2019s energy usage and hourly production\n<ul class=\"wp-block-list\">\n<li>Example 1: Usage: 3.0 kWh. Production: 1.9 kWh between 12pm and 1pm<\/li>\n\n\n\n<li>Example 2: Usage: 1.5 kWh. Production: 2.5 kWh between 1pm and 2pm<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>Estimate the amount of energy taken from the grid and sent to the grid. Often you just take the difference of consumption and production, but you can make special assumptions about variations within the hour because the NBT has no netting (in this case, we assume that the load was briefly greater than the PV production sometime between 1pm and 2pm).\n<ul class=\"wp-block-list\">\n<li>Example 1: Grid Import: 1.1 kWh. Grid Export 0.0 kWh between 12pm and 1pm<\/li>\n\n\n\n<li>Example 2: Grid Import: 0.1 kWh. Grid Export: 1.1 kWh between 1pm and 2pm<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>For energy taken from the grid: look up the cost of electricity for the given hour, and then multiply by the kWh.\n<ul class=\"wp-block-list\">\n<li>Example 1: Rate is $0.44\/kWh. Charge is $0.484 for the hour starting at 12pm<\/li>\n\n\n\n<li>Example 2: Rate is $0.44\/kWh. Charge is $0.044 for the hour starting at 1pm<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>For energy sent to the grid: look up the ACC for that hour.\n<ul class=\"wp-block-list\">\n<li>Example 2: Export Rate is $0.05\/kWh. Credit is $0.055 for the hour starting at 1pm<\/li>\n\n\n\n<li>Note that sending energy to the grid in the middle of the day is unfavorable. Buying 1.1 kWh costs 48.4\u00a2, but selling 1.1 kWh only gives you 5.5\u00a2.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<p>You then repeat this for all hours in a month. At the end of the month, any credits are applied against the charges, and in the unlikely event any credits are left over they are rolled over to the next month,<\/p>\n\n\n\n<p>If that\u2019s a little confusing, we don\u2019t blame you \u2014 the rules are very complicated. To help walk through the calculations, here\u2019s an example of one day with charts:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Example: One day of charges, offsets, and credits<\/h3>\n\n\n\n<p>To help explain NEM 3.0 billing, let\u2019s take a look at one day in August, for a SDG&amp;E customer. Looking through the following figure step-by-step can help clear up some confusion about how bills are determined.<\/p>\n\n\n\n<p>(a) Shows overlaid consumption and production load profiles for a generic customer in SDG&amp;E territory, for a day in August.&nbsp;<\/p>\n\n\n\n<p>(b) Has the same profile data, but the usage of energy is now shaded in. <strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-vivid-cyan-blue-color\">Blue<\/mark> <\/strong>represents energy purchased from the grid; <strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-vivid-green-cyan-color\">Green<\/mark><\/strong> represents self consumption of PV energy to offset loads, and <strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-luminous-vivid-amber-color\">Yellow<\/mark> <\/strong>shows the energy sold to the grid. Since the x-axis is hours and the y-axis is kW, the shaded areas represent the energy in kWh.<\/p>\n\n\n\n<p>Chart (c) shows the hourly total kWh in each of three categories. While the billing process takes place continuously, breaking these into hourly totals makes it easier to explain what\u2019s going on.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"341\" src=\"https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-ABC-1024x341.png\" alt=\"\" class=\"wp-image-7569\" srcset=\"https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-ABC-1024x341.png 1024w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-ABC-300x100.png 300w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-ABC-768x256.png 768w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-ABC-320x107.png 320w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-ABC-816x272.png 816w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-ABC-896x299.png 896w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-ABC-448x149.png 448w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-ABC-508x169.png 508w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-ABC-100x33.png 100w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-ABC-740x247.png 740w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-ABC.png 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>Charts (d), (e), and (f) take the data in chart (c) and show hourly kWh totals of grid usage, self consumption, and exports separately. As expected, there is no grid usage during the middle of the day because the PV system produces more energy than the house needs. Self consumption runs from about 6am until 8pm, and the system sends excess energy to the grid from 9am until 5pm.<\/p>\n\n\n\n<p>Charts (g) and (h) show the EV-TOU-5 rate, which represents the cost to buy energy and the savings of self-consumed PV energy ($\/kWh). Electricity costs the most from 4pm &#8211; 9pm, roughly $0.82\/kWh for SDG&amp;E.&nbsp;<\/p>\n\n\n\n<p>Chart (i) shows the hourly ACC export rate for 2023 ($\/kWh), which is the credit a customer receives for energy sent to the grid. It\u2019s very low until about 2pm in the afternoon, and is highest from 5pm &#8211; 7pm.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"410\" src=\"https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-3-1024x410.jpg\" alt=\"\" class=\"wp-image-7568\" srcset=\"https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-3-1024x410.jpg 1024w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-3-300x120.jpg 300w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-3-768x307.jpg 768w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-3-320x128.jpg 320w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-3-816x326.jpg 816w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-3-896x358.jpg 896w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-3-448x179.jpg 448w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-3-508x203.jpg 508w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-3-100x40.jpg 100w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-3-740x296.jpg 740w, https:\/\/aurorasolar.com\/wp-content\/uploads\/2023\/03\/NEM-3-0_Figure-3.jpg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p><strong>Grid usage<\/strong><\/p>\n\n\n\n<p>The customer\u2019s grid usage is spread out across on-peak, off-peak, and super-off-peak hours, despite having no grid usage during the middle of the day.
