Explorer : our latest product, for energy professionals everywhere

Today we are pleased to announce the launch of our latest product, Genability Explorer, a web-application for Energy Professionals.

The new Explorer is here

The new Explorer is here

Explorer provides energy professionals a user-friendly interface into Genability’s utility rate database and calculation engine. Explorer requires no software development or coding. It’s a self-service web-application, so just use your web browser to sign up and go. We’ve designed it to be as intuitive to use as your favorite websites, and yet as powerful and as accurate as the tools we provide to our enterprise customers.

So what can you do with Explorer?

Comprehensive Utility Rate Database

For starters, Explorer is backed by our electricity pricing tariff database, so you can search and access our rich set of data of utilities, their tariff rate plans, as well as their territories, times-of-use and seasons. We have their holiday schedules, critical peak pricing events, and in many cases their meter reading (billing period) dates. The rates we capture have all the details needed to match your customers’ bills, understand complex net metering rules, and what-if any energy project. All in one central location. We maintain the rates and keep them up-to-date so you don’t have to.

Powerful Rate Engine

Explorer also allows you to run calculations on our utility rate engine, again from directly within your web browser. This is the same utility rate engine that our utility and new energy customers use to run millions of calculations (including Pacific Gas & Electric, Tesla, Sunrun, EnerNOC and lots of others). Just select your tariff, optionally refine with your additional rate criteria, and specify your usage. For usage data, you can use our typical building profiles, or quickly enter the quantities from your bill. You can even paste in meter data in CSV format from your Excel spreadsheet. Results are instantaneous, and you can get back details broken down into flexible granularities and time intervals.

14 Day Free Trial

The best way to really understand the power of Explorer is to use it. So we have a 14-day free trial for you to do just that! This trial has no strings attached. During the trial, you can see exactly the same utilities and tariffs that a paying subscription would see, and access all the same functionality. Just sign up for a Genability User account, and create an Organization (existing customers can also start a trial – see the end of this blog post for details).

Plans Available for After your Free Trial

You have no commitment to become a customer when your 14 day trial has ended. But should you wish to, we are launching Explorer with one simple “Self Service Pro” plan. This is designed for teams that needs frequent, daily online access to our data and calculator. It includes unlimited users, so you can invite anyone within your team or company at no additional cost. It also includes unlimited access to our USA electricity tariffs. Finally it also includes unlimited calculations during the first 3 months of the subscription. Your team can run any number of calculations without the worry of incurring any additional costs. After three months the Pro plan then includes 1,000 calculations a month. The Self Service Pro plan is $499 per month (USD).

We will be rolling out a variety of Self Service plans at different price points and different tariff and calculation allocation levels later this year. Customers can choose the right plan for them. All our Self Service plans require no obligation, so customers can cancel or switch between plans at any time. Changes or cancellations become effective at the end of the month you change or cancel your plan.

Next for Explorer: Additional Markets & Functionality

Along with additional pricing plans, over the next few months we will be rolling out a number of exciting upgrades to Explorer. These will include new markets (today the Explorer Self Service Pro Plan gives access to our USA data). We also have a series of feature upgrades in development or planning. We’re excited to see and hear what customers’ experiences are using Explorer, and as always will prioritize your feedback and suggestions in our product roadmap. Let us know!

More Self Service Products in the Works

This release of Explorer is exciting for us in another way too. It marks the first in a series of product releases targeted at new classes of customer. Historically our product offerings have been focused on enterprise customers who have their own proprietary energy platform along with a software engineering teams and high transactional volumes that our APIs are built to handle. Our goal is to make our capabilities accessible and valuable for all segments of the new energy community, and this release of Explorer is an important step towards that goal.

You can read more about Explorer on our website. Or better yet, go sign up for a free trial! It’s simple, obligation free, and doesn’t even require a credit card.

A note to existing Genability customers. As a Genability customer you already have an Organization set up, and you probably already have a Genability user account. To start your free trial, just log into the Dash site here and click on the Explorer Free trial button.

New Solar Incentives in Illinois, Net Metering Ends for Duke Energy South Carolina

The roller coaster for solar in the U.S. (call it a Solar Coaster?) keeps rolling this summer.  The state of Illinois has finalized the credit values for its Adjustable Block Program, which provides solar owners with an upfront payment for 15 years of estimated solar production.  Meanwhile, in South Carolina the state legislature failed to increase the net metering cap and Duke Energy has met its 2% limit. Starting on August 1, 2018 full net metering closes for Duke Energy SC customers and will be replaced by the Purchased Power Rider. First the good news for solar developers:

Adjustable Block Program in Illinois

In June the Illinois Power Agency published the final values for the Adjustable Block Program(ABP), and Genability has published the ABP incentives for your use. For those who are unfamiliar, the ABP offers a per kWh credit for the first 15 years of estimated solar production to be paid upon interconnection for systems under 10 kW.  The amount of the credit varies according to utility and system size and is in addition to the customer’s monthly net metering credits.

Commonwealth Edison Ameren – Illinois Mid American – Illinois
Under 10 kW 7.297¢/kWh 8.51¢/kWh 8.51¢/kWh
10 – 25 kW 7.323¢/kWh 7.87¢/kWh 7.87¢/kWh

The Illinois Power Agency has selected a program administrator and is expected to start accepting applications for the program this fall. We have made these incentives available via our API to allow our customers to include the ABP in their savings calculations ahead of the program’s official opening.

End of Net Metering for Duke Energy – South Carolina

This spring it seemed that the South Carolina legislature was prepared to increase the Net Metering cap in South Carolina from 2% to 4%, but the bill that emerged from committee did not up the cap.  On August 1st, Duke Energy will close Net Metering and move solar customers onto the Purchased Power Rider that compensates solar customers at a lower rate for power provided to the grid.  Due to the earlier merger of Duke Energy and Progress Energy, Duke Energy currently maintains two sets of rates within South Carolina (and North Carolina), thus the two columns in the table below:

Duke Energy Duke Energy (formerly Progress)
Fixed Charge $11.07 $8.05
Summer On-Peak Credit $0.1035 $0.0963
Summer Off-Peak Credit $0.0334 $0.0346
Winter On-Peak Credit $0.0661 $0.0611

For all of Duke Energy, On-Peak is defined as 1 PM to 9 PM in the Summer and 6 AM to 1 PM in the Winter, aligning reasonably well with the peak hours of solar production. Genability has created new Purchased Power Rider versions of all Duke Energy SC tariffs and will make them the default post-solar tariff in our Switch API on August 1.

Massachusetts SMART Incentives Now Available

Later this year, Massachusetts will close out it’s SREC program replacing it with the new Solar Massachusetts Renewable Target (SMART) incentives.   While there are still a few details left to be finalized, Genability is able to model the proposed SMART incentives for our customers and has made the new incentives available via the Incentives API.

What are the Smart Incentives

The new SMART Incentives guarantee solar customers a fixed compensation rate for every kWh produced by their solar system over the first ten years, called the Base Compensation Rate.  The Base Compensation Rate varies by utility territory and will decrease over time as each tranche is completed.  Here are the initial Base Compensation Rates:

Utility Base Compensation Rate (Tranche 1)
Fitchburg Gas & Electric d/b/a Unitil $0.31126
Massachusetts Electric d/b/a National Grid $0.31126
Nantucket Electric d/b/a National Grid $0.34000
NSTAR d/b/a Eversource Energy $0.34000
WMECO d/b/a Eversource Energy $0.28576

How SMART Incentives are Applied

While the customer is guaranteed the full Base Compensation Rate for all kWh produced by their solar system, they will actually get two credits on their utility bill under the SMART incentive program.  The first credit is the traditional Net Metering credit that solar customer receive in Massachusetts.  This doesn’t change from the current regime.

The second credit, called the Solar Incentive Payment, will be the difference between the Base Compensation Rate and the Value of Energy.  This Solar Incentive Payment will be applied to the customer’s bill as a credit, effectively topping up the Value of Energy to the level of the Base Compensation Rate.

Genability has modeled the Solar Incentive Payment in its SMART Incentives.  Since the Solar Incentive Payment represents a top-up on the Value of Energy, its value changes not just by utility but also by tariff.   In the table below are all the permutations of SMART incentives along with the customer attributes that indicate eligibility.

Incentive Base Compensation Rate Value of Energy Solar Incentive Payment Eligibility Parameter(s)

Behind the Meter Smart Incentive for Unitil – Massachusetts Tranche 1 $0.31126 $0.22535 $0.08591

Including SMART Incentives in your Proposals

Now that the SMART Incentives are available via the Incentives API, you can begin including them in your solar savings proposals.  For each month or year in your lifetime savings calculation, you will multiply your solar production by the Solar Incentive Payment for the first ten years to reflect the SMART incentive compensation.

While the SMART Incentive program is not expected to open officially until August or September of 2018, Genability is making these incentives available in our API so that you can get your interconnection paper work started before the program goes into effect.  So don’t delay, calculate your customer’s savings in Massachusetts using the SMART incentives today!

New Hawaii Solar Programs – Smart Export and Customer Grid Supply Plus

Starting on 2/20/2018, the three Hawaiian investor-owned utilities will offer two new programs for customers with solar: Customer Grid Supply Plus and Smart Export.  Both programs offer export credits for power provided to the grid, an option that has not been available in Hawaii since the Customer Grid Supply programs closed in 2017. Genability has just made these two programs available for Hawaiian Electric Co (HECO), Hawaiian Electric Light Co (HELCO) and Maui Electric Co (MECO) for use in your solar proposals.

Customer Grid Supply Plus

The Customer Grid Supply Plus (CGSP) program, like the Customer Grid Supply (CGS) program it replaces,  provides solar customers with an export credit for power provided to the grid.   Here are the new (lower) export credits under CGSP:

  • O’ahu 10.08¢/kWh
  • Hawai’i Island 10.55¢/kWh
  • Maui 12.17¢/kWh
  • Moloka’i 16.77¢/kWh
  • Lana’i 20.8¢/kWh

In addition, customers enrolled in the CGSP program must have “new equipment that allows the electric utility to manage power from the system when necessary to maintain a stable grid”.

To support the CGSP program Genability has created new versions of all the residential tariffs in HECO, HELCO and MECO.  They can be identified by the tariff code ( “-CGSP) and tariff name ( “, Customer Grid Supply Plus”).  For example, the new tariff for HECO’s default residential offer is: R-SE: Residential – Smart Export

Smart Export

The Smart Export (SE) program is a completely new structure for the Hawaiian utilities that requires the customer to have energy storage installed.  With storage, the utility will provide solar customers with higher export credits, but only outside of peak-solar hours.  Any exports to the grid between 9 AM and 4 PM receive no credit, while exports to the grid between 4 PM and 9 AM are credited at the rates below:

  • O’ahu 14.97¢/kWh
  • Hawai’i Island 11¢/kWh
  • Maui 14.41¢/kWh
  • Moloka’i 16.64¢/kWh
  • Lana’i 20.79¢/kWh

Genability has created new Smart Export versions of each residential tariff in HECO, HELCO and MECO. They can be identified by the tariff code (+ “-SE) and tariff name (+ “, Smart Export”).  For example, the new tariff for HECO’s default residential offer is: R-CGSP: Residential – Customer Grid Supply Plus

Solar Savings Calculations

Customer Grid Supply Plus and Smart Export both require the customer to install a dual register meter to allow for instantaneous netting of imports from and exports to the grid.  With a dual register meter, the utility measures imports and exports in real time rather than by 15 minute or hourly intervals.  Genability models the intra-hour variability when calculating solar savings.  Visit our blog post Accurate Savings Forecasts: California’s NEM 2.0 & Hawaii’s Customer Grid Supply to learn more about how we do it.

Impact on Solar Savings

Finally the most important question, how do these new programs impact customer savings with solar?  Genability has run savings calculations for typical residential customers with solar systems that offset 80% of the customer load.

Utility Customer Self Supply Customer Grid Supply Plus
HECO 13.3¢/kWh 16.5¢/kWh
HELCO 16.7¢/kWh 23.2¢/kWh
MECO (Maui) 14.6¢/kWh 22.0¢/kWh
MECO (Moloka’i) 19.2¢/kWh 27.0¢/kWh
MECO (Lana’i) 19.9¢/kWh 29.4¢/kWh

As you can see getting export credits, even at a considerable discount from the retail rate, greatly improves the avoided cost of power (ACP) throughout Hawaii.  We did not calculate the typical ACP for the Smart Export tariff because the charge/discharge strategy for the battery will drive a significant portion of the savings.

It’s encouraging to see the economics of solar get better in Hawaii.  We look forward to seeing lots of proposals run through our APIs.  Happy quoting!

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.
