Estimating kWh from a Potential Solar Customer’s Bill Amount

Do you have a potential solar customer’s 12 months of bills or their annual bill amount for electricity? If so, we can now estimate energy usage from that information!

It is quite common for potential solar customers to not know how much energy they are using but to have an idea of how much they are paying for electricity. For situations like this, Genability’s Bill Solve feature in our Calculate API is a useful tool for our Switch customers. After creating a site for your potential customer in our API, you can enter the cost of the customer’s bill and our calculator will estimate their electricity usage. You can then use this kWh value to run solar savings calculations.

Our Switch customers found a lot of value in estimating electricity usage for a single monthly bill through our Bill Solve feature so we made it more useful by upgrading this feature to work for annual bill amounts too! Now for situations where potential solar customers know how much they spend annually on electricity, you can use our Bill Solve feature to estimate the customer’s annual kWh.

Although we support estimating annual kWh based on annual bill amounts, the more specific information you provide to the Bill Solve, the more precise the customer’s electricity usage will be. Here is a list of Bill Solve methods ranked in order from the most precise method to the least precise method:

  1. Turn the monthly bill cost into monthly kWh using the exact billing period dates (e.g., 7/13/2017 to 8/12/2017)
  2. Turn the monthly bill cost into monthly kWh using approximate billing period dates (e.g., 7/1/2017 to 8/1/2017)
  3. Turn the annual bill cost into annual kWh using exact annual dates (e.g., 7/13/2016 to 7/13/2017)
  4. Turn the annual bill cost into annual kWh using approximate annual dates (e.g., 7/1/2016 to 7/1/2017)

Based on this information, we recommend using the bill amount of a monthly bill with exact billing period dates to solve for a customer’s usage since this will provide you the most precise kWh. However, you are welcome to use our Bill Solve feature to estimate a customer’s usage based on an annual bill amount if it is common for your potential solar customers to know this information.

If you are an existing Switch customer of ours who would like to add our Bill Solve feature in your proposal tool, please take a look at our developer How-To on Turning Bills into kWh and reach out to support@genability.com if you have any questions. If you are not our customer but you are interested in utilizing our Bill Solve feature for your solar proposals, please reach out to sales@genability.com to find out more about our Switch product today!

New York PSC Guidelines on Presenting Solar Savings

Effective December 1, 2017, solar developers in New York are required by the New York Public Service Commission (NYPSC) to meet precise guidelines (PDF Download) when presenting savings estimates.  Genability has reviewed these requirements and we have made some data upgrades for New York so that our solar customers can comply with these new requirements without any change to their API integration.  First, let’s review the new savings requirement:

When marketing materials or information conveyed to mass market customers or potential mass market customers includes savings estimates, CDG and mass market on-site DG providers must include, in addition to any other forecasts used, a forecast using the following baseline: a three-year average of actual historical utility rates for the three most recent calendar years for which data is available, for the customer’s actual utility and service class. The provider may choose to apply an assumed escalation rate of up to 3% per year to this baseline in generating a forecast; if the provider does so, it must disclose the escalation rate used. The forecast generated must estimate savings for the same potential contract term as any other forecast provided. This forecast must be presented with similar prominence to other forecasts and all forecasts must be appropriately labeled to permit customers to understand their source.”.

The New 3 Year Average Tariffs

Genability has created 6 new tariffs that reflect the three-year average of utility rates (listed below) that can be used to calculate solar savings.  To calculate the three year average, we took an approach that incorporates average rates as mandated by the PUC without losing the mechanisms (rates that vary by season, tier and territory) that drive electricity pricing.  Assuming equal usage across all three years we calculate the 3 year, time-weighted average rate for each of the following components:

  1. Fixed Rates
  2. Seasonal and/or Tiered kWh Rates
  3. All-hours kWh Rates by Territory

The resulting PSC compliant rate maintains the seasonal and tiered components that impact the solar savings calculation, while averaging the remaining components equally over three years.  These new tariffs should appear in our customer’s tariff dropdown lists and appear at the bottom of the list (whether it’s sorted by customerLikelihood or alphabetical order).

Utility Tariff Code Tariff Name Master Tariff Id
Consolidated Edison EL1-PSC Residential and Religious – 3 Year Average for 2017 3296036
Orange & Rockland 1-PSC Residential – 3 Year Average for 2017 3296037
New York State Electric & Gas SC1-PSC Residential – 3 Year Average for 2017 3296050
National Grid – New York SC1-PSC Residential and Farm – 3 Year Average for 2017 3296051
Central Hudson Gas & Electric 1-PSC Residential – 3 Year Average for 2017 3296080
Rochester Gas & Electric 1-RSS-PSC Residential – 3 Year Average for 2017 3296079

Impact on Solar Savings

We have performed an analysis of the Avoided Cost of Power (ACP) in each New York utility by using these new 3-year average rates and comparing it to Genability’s comprehensive tariff model (more about our solar savings methodology).  The impact depends on both the specific prices in a utility/region and of Intelligent Baselining on the distribution of usage across the hours in the year.

The 3 Year Average delivers higher ACPs for Consolidated Edison’s Zone J (+5.6%) and National Grid – New York’s Capital Region (+6.5%).  This reflects both the effect of higher prices during the Polar Vortex of 2014 and the application of the average price for each hour (as opposed to the hourly usage and daily prices used by Genability’s model).  Expect that higher ACP to diminish next year as the 2014 prices are replaced by 2017 prices in the 3-year average.

In contrast, the 3 Year Average delivers lower ACPs for New York State Electric & Gas West region (-9.5%) and Rochester Gas & Electric (-4.6%).  For these utilities, the current Genability approach calculates a higher ACP because our climate-specific typical usage profiles assign more usage to days when prices are higher.  In addition, the western part of the state was less impacted by the variable price rises in the winter, like 2014’s Polar Vortex.

If you are interested in the results of our ACP analysis, please email us at support@genability.com and we’re happy to share our findings.

Run Down of GDN Updates

GDN

We have been working hard enhancing GDN with lots of great new how to’s, articles and information. We want our API customers to have the best resources possible. Below is a quick rundown of the latest and greatest updates….

Costs broken down by Charge Class

Did you know you can exclude rates from a calculation based on their charge class? Charge class denotes if charges are for Transmission, Distribution, Supply, Tax and a number of other classes. Excluding these can be useful in a number of use cases. Some of our customers involved in deregulated markets or energy procurement, use this to understand various components of the bill, price to compare (PTC) and which pieces of the cost structure they can reduce.

The `excludeChargeClass` is the request parameter that handles this. All our calculators take it as an argument. Here’s the on demand cost calculator:
http://developer.genability.com/api-reference/calculation-api/cost-calculation/#run-a-calculation

A New How-To to get the right level of detail back

We continue to refine our recently published How to on using the Group By and Detail Level arguments on our calculators to get the precise granularity of results back that you need. In particular we’d like to highlight a recently added option to get results broken out by distinct charge types, seasons and time of use buckets, and tariff version, that is particularly useful for bill breakdown analysis (a `detailLevel` of `CHARGE_TYPE_AND_TOU`), and stacked bar charts. In fact our customer Pacific Gas & Electric uses this option on their customer engagement website to drive their stacked bar charts of billing costs.

http://developer.genability.com/how-to/detail-level-group-by/

It’s all about that Base(line)

The Typical Baseline API gives you regional typical electricity usage across a range of building types. It’s useful when you don’t have a good picture of usage data for a customer or region. We’ve added three new examples to the API page, in particular showing you how to size the typical profile, and how to get usage data back for a specific date range.

http://developer.genability.com/api-reference/shared-api/typical-baseline/

Domain Expertise on Territories Expanded

The Territory API reference page was updated with several new examples

http://developer.genability.com/api-reference/tariff-api/territory/

Lets end with Javascript!

We added an example of how to use Javascripts Fetch to make “promisified” calls to our APIs.
http://developer.genability.com/api-reference/basics/security/#javascript-browser-using-fetch

Whenever Javascript Promises came up in discussions at the office, our alumni Michael would fire up the 80s classic. So to play us out … https://www.youtube.com/watch?v=H8Q83DPZy6E

The Methodology Behind our Monthly Residential Rates Newsletter

Genability-Mail---Fwd_-September-Residential-Rate-Updates-1

Every month Genability updates thousands of Tariffs. These changes can be as small as a simple rate increase or as large as a whole new rate structure. So for just over a year now, around the 10th of each month, we have sent out a summary of those changes in our Monthly Residential Rate newsletter to help our customers better understand and anticipate these changes.

The feedback has been overwhelmingly positive so we thought we would share a bit about all the background number crunching and data checks that go into those updates.

Tracking Avoided Cost of Power (ACP)

Every  month our Data & Operations team processes thousands of rate changes, about 2,000 tariffs per month.  While the volume of changes can be dizzying, we need a way to ensure the rate changes are free from errors.  One way of doing so is to use a tool that’s available to our Switch customers: Savings Analysis.
Along with internal data quality checks, we utilize Savings Analysis as a proxy for data quality by tracking ACP changes for the top utilities across the country.  From there, we execute a twelve month calculation via Genability’s Calculate API to see which individual rates changed.  Lastly, we check that the individual rate changes were entered properly and make necessary corrections.  Not all changes will result in significant changes to ACP so we highlight changes that incur at least a 0.1¢ change to a typical customer’s ACP.

How do we use Savings Analyses?

We set up prototype test accounts within the service territory of major utilities across the United States with a standard consumption profile and solar profile that represents a typical customer (usage of 8400 or 9400 kWh per year, and a 4 kW system).  Each morning we execute a Savings Analysis against all these accounts using the default residential tariff of the utility.  For example, for Consolidated Edison we use EL1, for Pacific Gas and Electric we use E-1.  Then we use an internal engine that looks for any differences between the current Savings Analysis response and the day before.  We review any differences returned by the engine against tariff documentation to ensure the changes are correct.  If there are any discrepancies we quickly correct them and then execute another run of Savings Analyses.  

NEM 2.0 and Beyond

Since we started sending out these monthly updates this method has evolved over time.  In the ever changing landscape of net metering, the introduction of NEM 2.0 and forced tariff switch, we’ve taken advantage of our solarPvEligible logic to track ACP when a customer must select a new tariff after going solar.  This gives our customers who subscribe to the Monthly Residential Rate Update a real-world view into what caused the ACP change and how tariff switching affects ACP.  Where utilities enforce a tariff switch, our solarPvEligible logic will pick the most likely tariff after going solar.  For customers of utilities that do not require a tariff switch when going solar, the post solar tariff is the same as the pre solar tariff.  

If your organization would benefit from the great information in the Monthly Residential Rate Newsletter you can sign up for it here

We are always here to help with any of your rate questions –  just email us at support@genability.com.

Genability Covers the Netherlands

We’re pleased to announce that we’ve added Dutch residential utility rates to our database! Our list of covered countries now includes the US, Canada, Mexico, Australia, South Korea, UK, France and the Netherlands.

Electricity Market Overview

The Netherlands population is just over 17 million and the average household consumes about 3,300 kWh of electricity per year. The country’s large coastline heavily influence its climate, producing cool summers and moderate winters. This along with relatively smaller homes (1200 sqft on average) contribute to lower energy consumption. In comparison, an average household in California uses 6,700 kWh annually.

Residential customers in the Netherlands pay between €0.16 and €0.20 per kWh, placing them among the top ten countries in Europe with the highest electricity rate.   High prices are primarily driven by government taxes and fees that fund both low income consumers (each customer gets a €25.71 credit against their monthly bill) and efforts to migrate to more renewable sources of energy.

Like most of Europe, the Dutch electricity market is deregulated giving customers the ability to shop for an energy supplier that meets their needs. Similar to Texas, the United Kingdom and most of Australia, the Netherlands requires each customer to choose their electricity supplier, rather than be defaulted to a provider of last resort. While customers are free to pick from 35 different suppliers, over 80% opt for the top three suppliers (Essent, Nuon and Eneco aka Stedin) and 99.5% of customers are served by the top seven (see chart below).

 

Screen Shot 2017-09-01 at 1.48.50 PM

You Choose Your Tariff

There are over 8 million residential electricity customers in the Netherlands subscribed to one of about 250 tariffs, offered annually by electricity suppliers. Since a customer is required to pick their supplier, that decision likely hinges on the rate plans offered by suppliers. While each supplier offers its own flavor of tariffs, targeted to different customer needs, there are similarities across supplier offerings. Common choices customers see when selecting a plan include:

  • Type of power (Conventional, Renewable, Wind, Hydro, etc.)
  • Variable Market Price vs. Fixed Price (1, 3, 4 and 5 year contracts)
  • Single or Double (Time of Use) Meter

The Dutch suppliers label their time of use tariffs Dubbele Meter tariffs, for the two meters that are required to measure on versus off peak usage. Only customers that already have a double meter can subscribe to these tariffs.

Wij Begrijpen Nederlandse Tarieven

A couple of points worth highlighting when using Netherlands tariffs in Genability’s tools. First, we’ve organized and presented the Netherlands tariffs completely in their native language (Dutch) rather than English.  This applies to tariff names, rate names, time of use definitions, tariff properties and territory names.

Secondly, we have collected and are making “Supplier” tariffs available for customer use, rather than the distribution utility’s tariffs. Unlike other markets, supplier tariffs in the Netherlands are more standardized, manageable and publicly available, similar to regulated tariffs in the US. Dutch customers are also more familiar with their supplier and supplier tariff since each customer picks their plan and is billed by their supplier.

Netherlands Tariffs Available Now

Curious about Netherlands tariffs? Supplier tariffs are now available throughout the Netherlands and available to use in our APIs, including our Tariff APIs, Signal, Switch and Conduct. If you are an existing customer you most likely already have access, but feel free to contact us if you have questions about licensing or permissions.

Next up, we are going to add Germany residential rates.

Our Developer Site Gets a Major Update

GDN

If you haven’t visited our developer website in a while, you will be pleased to see we have completed a major upgrade to it.

Genability Developer Network (or GDN) is our website that helps software developers and teams get the most out of Genability’s products with technical documentation, examples, reference guides and How-To’s. Over the summer we put a lot of effort into a new version and it is jam packed with new content that helps you integrate quickly and get more from our offerings. It’s been live for a few weeks now and we’re really happy with the initial results. So what did we do?

Changes You Can See

Refreshed Look

The first thing you will notice is that the look and feel is different. We’ve made the layout more responsive. On a desktop it takes advantage of your whole window, and on a mobile device it adjusts nicely to fit your screen. The navigation is new, but should be familiar to those who use our Dash web application or our company website. Each content template has a newly designed layout that carefully considers its purpose. The font, colors and iconography are also new. In fact, we’ve updated nearly everything but the pink!

Cleaner Organization of its content

We also took the opportunity to refine the way we structure and categorize our content in the site. In particular, we wanted to do a better job of making it clear what the purpose of each section was. All content now falls into one of four main sections, each with a very specific purpose.

Quick Start – is the place to begin when you are new to our developer tools.
Tutorials – pick your use case and walk through a step by step learning exercise.
How To’s – dive deeper into specific, focused topics.
API Reference – each API and data types requests and responses documented with reference materials and examples.

We want to make clear to the visitor that there is a logical “journey” through the site. Starting with the Quick Start, then moving on to the learning oriented Tutorials, followed by finding the API References (which are information oriented) and the How-To’s (which are problem oriented) for the specific task that prompted you to visit.

Lots of Improvements to the Actual Content

Most of the work has actually been in writing and editing the content itself. First off we have a significantly updated Quick Start Guide for those who are new to our APIs. We’ve also done quite a few edits to our two existing Tutorials, so they are more complete, and more focused on a logical end-to-end task flow. The How-To’s needed and got a lot of love (with more to come). Repetitive content and sections were removed and we put a particular focus on making sure a how-to article was comprehensive and on topic. There is more to do with the How-To section, but this version is a major improvement. Then the all important API Reference section was given an audit for completeness. It was in pretty good shape but it was none the less given some spit and polish.

Changes Behind the Scenes

For those of you technically inclined, we did sizable platform changes as well. The previous version of the site used a cloud CMS called Harmony. It lacks a robust version control mechanism, so for a while we’ve kept our content, written in markdown, in a Github repository. We used a simple, custom python script to convert it into HTML snippets. Copying and pasting these changes to Harmony got old a long time ago. So in this upgrade, we’ve migrated to Jekyll, with the site hosted as static HTML on Amazon S3. We use the wonderful Travis CI to automatically QA and run this process when triggered by a check-in for our development (a.k.a. staging) site. Travis CI also manages a Pull Request initiated workflow including reviewing and pushing changes to production in a “Continuous Delivery”-esque fashion. This system has been in place for a while now and we are happy that the frequency and quality of our updates to content have increased considerably. The whole company has been trained and is involved.

More Upgrades to GDN Planned

This was a big update, with changes to the underlying management and hosting, new theme and lots of content. It’s also a foundation for continued improvements such as:

Shared Postman Collection – We use Postman extensively at Genability, and will publish all the GDN site’s API calls as a collection
Better Search – to help find the answers you are looking for.
More Content – Our new processes help facilitate this with easy and safe promotions.

Give Feedback Get Messenger Bag

We often hear from folks “we love the pink” or “your APIs are really well documented”. While we love the positive feedback, we are always striving to give our customers the best information. So with this in mind we challenge you to give us some feedback or point something out that is missing or unclear. Give us a suggestion that we use to improve our customer experience and we will give you a free Genability messenger bag! So please do send us your feedback to support@genability.com.

NEM Rules Change Across the U.S., Genability Has it Covered

Over the past few months, the reform of Net Metering rules has impacted several utilities that are in active solar markets.  Genability has been tracking these changes closely and has modeled the new NEM rules for your use with the Switch API.

Arizona Public Service – New Rates Effective 8/19/2017

As of Saturday August 19, 2017, Arizona Public Service (APS) has announced completely new rate structures for all of their residential and commercial customers.   Genability had previously modeled these rates as proposed rates, and now they are fully available without the “proposed” label.  

Under APS’s new Net Metering regime, new residential solar customers are required to switch to 1 of 4 residential tariffs:

  1. R-2. This tariff includes a $8.40/kW on-peak demand charge(3PM to 8PM).  
  2. R-3.  This tariff has both kWh and kW charges with time of use.  The summer on-peak period (3PM to 8PM) has a $17.44 /kW demand charge, with Winter On-Peak at $12.24/kW.  
  3. TOU-E. This tariff has 3 TOU periods, including a super-off peak from 10 AM to 3 PM.  It has no demand charge, but does retain the per kW of installed solar fixed charge from E-12.
  4. R-TECH.  This tariff requires that a customer have either 2 primary technologies (Solar, Battery or EV) or 1 primary technology and 2 secondary technologies (Variable Speed Pool Pump, Variable HVAC Pump, Smart Thermostat, Automated Load Control, Smart Water Heating).  It features a $20.25/kW On-Peak demand charge, a tiered Off-Peak demand charge ($0 up to 5 kW, $6.50 above 5 kW) and low per kWh rates (5.75¢/kWh Summer On-Peak, 4.75¢/kWh all other hours).

Just as important are the new rules for power exported to the grid. All four of the tariffs above compensate excess generation through the Resource Comparison Proxy at a rate of 12.9¢/kWh with exports resolved in real time.  Genability will set the solarPvEligible flags on all the new residential tariffs after the 9/1/2017 deadline, so your APS customers automatically switch to a solar-eligible tariff post-solar.

San Diego Gas & Electric – TOU Tariff Switch Required This Fall, New TOU Periods

San Diego Gas & Electric (SDG&E) was the first of the California investor-owned utilities to close NEM 1.0.  As such, it was grandfathered by the California PUC from requiring solar customers to switch to a Time of Use tariff post-solar.  SDG&E has already filed the new tariff and time of use structure for DR-TOU with the California PUC and Genability has made the new proposed TOU tariff available via our Switch API.  The new on-peak time of use period will be from 4PM to 9PM, Monday through Friday all year round.   Once the tariff goes into effect later this year, we will set the solarPvEligible flags to force a switch to the time of use tariff in SDG&E.

Based on an analysis of typical SDG&E customers with an 80% solar offset, we see the Avoided Cost of Power (ACP) in SDG&E  dropping from 26.8¢ to 19.8¢ with the required move to DR-TOU.

NV Energy South & North – More Tariff Changes Coming?

In June of this year, Nevada Governor Brian Sandoval signed bill AB-405 allowing solar customers to receive a credit for all power exported to the grid at 95% of the retail rate.  Based upon this new legislation, Genability made the proposed tariff available in our system under the tariff code “RS-NEM-95PCT”.  The proposed tariff replaces the fixed solar export credit from the current “RS-NEM” tariff and replaces it with a solar export credit that is 95% of the retail rate.

However it appears that all is not yet settled for NV Energy’s solar customers.  In NV Energy’s filing with the Public Utility Commission of Nevada to implement AB-405, the utility includes many strategies to minimize the export credit provided to solar customers.  The proposal includes 2 demand charges, higher fixed charges, a 4-period TOU definition and higher per kWh rates overall.  It remains to be seen how the Public Utility Commission of Nevada will rule on this filing, but you can be sure we’ll be following it closely.

Rocky Mountain Power: Utah – New Rules Under Negotiation

Another NEM battle is occurring in next door Utah where Rocky Mountain Power (RMP) has proposed higher fixed charges, demand charges, and a wholesale credit for energy exported to the grid.  After last week’s meeting, the Utah Public Service Commission has asked RMP to sit down with solar advocates to work out a compromise.

Genability has not yet created a proposed tariff for Rocky Mountain Power in Utah as there are too many important details still outstanding before the utility commission.  As soon as those details are finalized, Genability will create a proposed tariff so our customers can use it in the Switch API.

If you have a question about a specific current or proposed rate, please let us know at support@genability.com.  Chances are we already support that rate or working on supporting it.  We’re always happy to answer your questions.

France Tariff Triomphe

arc de triomphe Paris #1

We’re pleased to announce that Genability has added French residential utility rates to our database! Our list of covered countries now includes the US, Canada, Mexico, Australia, South Korea, UK and France.  We plan to add coverage for Germany and Netherlands later this summer.

France Electricity Market Primer

Government-owned, Electricité de France (EDF) is the largest energy company in France, and along with its subsidiaries dominates all market sectors, including transmission (RTE), distribution (ERDF), generation and retail supply. EDF owns 80% of the country’s installed capacity and generates 86% of its electricity production. At the end of 2013, 91% of the country’s 28 million residential customers were under regulated tariffs mostly with EDF. And although customers have been able to select their retail provider from EDF and a few dozen smaller retail suppliers since 2007, most customers have remained with the incumbent EDF.

France is an unique market because of the significant proportion of commercial and residential buildings that utilize electric heating systems, as compared to other European countries with some estimates as high as 72% vs just 5% in Spain. In the winter and cold weather this creates a peak in demand usually around 7 pm, when people get home and turn on their heat, lights and appliances. France has sought to manage the demand with some conventional and some complex rate structures.

Ace of Base (wait, weren’t they Swedish?)

EDF’s regulated residential tariff, called tarif Bleu, actually comes in three different options. The first, which the majority of residential customers are on, is called “Option Base”. This consists of a flat consumption rate (€0.15/kWh) plus an annual fixed charge which is based on the customer’s power connection. These rates are fixed year-round and are the same across all regions of France. Option Base works best for low or high consumption customers with a highly variable load that cannot easily be shifted to a time of day, when a TOU rate might be more economical.

What Time-of-Use do you have?

The second Option is EDF’s time-of-use (TOU) offering, aka “Option Heures Pleines / Heures Creuses”. We got excited when we read this, as it is one of the more complex residential TOU tariffs we’ve seen to date. While rates themselves are pretty straightforward (€0.11/kWh Off-Peak, €0.16/kWh Peak, fixed seasonally and throughout the country), the complexity lies in the TOU period definitions. More specifically, the hours of the day that are characterized as “peak” and “off-peak” vary by region and can change over time in any single location. For example, a customer in Paris postal code 75001 may be assigned one of two time slots (off-peak hours from 11 pm – 7 am or 11:30 pm – 7:30 am). All other hours are considered peak. In comparison, a customer in Lyon postal code 69001 may be assigned one of three time slots (off-peak hours from 11 pm – 7 am or 11:30 pm – 7 am or 10 pm – 6 am). Based on our analysis, there are about 80 different TOU periods currently offered throughout the country. Customers cannot choose nor switch to a preferred time slot. They are created and assigned by the power distributor ERDF, according to the conditions and local capacity of the distribution network.

Tricolor Days

EDF

A year to date view of Option Tempo Coleur du jour – via EDF

We’ve saved the best for last. The third and final option is called “Option Tempo” and is a tariff with consumption rates that vary dynamically by “day type” and time of day. By “day type” we mean that the year is divided into 22 red days (most expensive), 43 white days, and 300 blue days (least expensive). The color of the day is announced a day in advance by EDF, and is closely related to the weather forecast, which in turn influences the expected demand for electricity on the grid. Unlike the TOU Option, the Tempo Tariff’s Off-peak hours are always 10 pm to 6am throughout the country. This tariff rewards customers that can curtail their load on the 22 days of the year when the grid is most stressed (typically January) with the lowest consumption rates  EDF has to offer on any tariff (€0.10/kWh Off-Peak, €0.115/kWh Peak). This tariff works best for customers with large loads and the flexibility to shift load on a day’s notice.

Allons-y!

All EDF’s residential Tariff Bleu options are now available to use in our APIs, including our Tariff APIs, Signal, Switch and Conduct. As with all other markets, we have not only the tariffs and their rates, but also complete TOU definitions, holiday and Tempo Day calendars, TOU regions and everything else you need to accurately calculate costs, savings and schedules in France.

We plan on adding coverage for Commercial and Industrial (C&I) Tariffs later in the year, as well as typical electricity and solar profiles for France. Stay tuned for an update.

Sign up today and bring transparency and clean power to France. If you are an existing customer you most likely already have access, but feel free to contact us if you have questions about licensing or permissions.

New Net Metering Tariff Available for Nevada Energy

When Nevada Governor Brian Sandoval signed AB-405 on Friday he removed a great deal of uncertainty surrounding Net Metering in Nevada.  Under AB-405, new solar customers in Nevada are guaranteed a net metering credit for the next twenty years tied to the retail price of power.  Genability has already made the first version of this tariff available in our system as RS-NEM-95PCT : Residential Single-Family Net Meter – 95 Pct.  This is now available for our Switch customers to use as a post-solar tariff.

The new tariff structure compensates solar customers for power provided to the grid at 95% of the retail rate.  The true-up for this compensation happens at the end of each billing period and is guaranteed for the next 20 years.  The net metering credit begins at 95% and will decrease over time as each 80 MW blocks is filled. This replaces the previous rate structure, that compensated the customer at a fixed rate scheduled to decrease to only 5¢/kWh by 2020.

The new rate structure is now available via our APIs and our web applications, Dash and Explorer.  Once the Public Utilities Commission of Nevada makes the new NEM rate effective, we will enforce the post-solar tariff defaulting logic in the Switch API to ensure that your analyses reflect the newly required tariff.  We’re thrilled to see the Nevada market re-open and glad to do our part to help sell more solar in Nevada.
