Can a simple model predict future PV adoption? (Yes—if done right)
Utilities across the U.S. are eager to know how much PV their customers will adopt, as this adoption can impact both revenues (from reduction in energy purchases) and costs (linked to distribution operation and intermittency mitigation). Having seen the explosive...
What is the value of accurate solar forecasting for utility-scale PV plants?
The importance and source of solar forecasting With an increasing number of installed utility-scale PV plants and a growing need for predictable energy generation, the solar industry has started paying attention to solar forecasting. The reasons behind this are: Solar...
Are utilities prepared to handle DER administration through their 20-year lifecycle?
Today, utilities are facing pressure from customers and regulatory agencies to approve DER (distributed energy resource) applications for interconnection quickly. However, utilities will need to track and manage interconnected DERs through their lifecycle, which can...
Can Hawaiian Electric convince customers to invest in solar and battery storage without pushing them off the grid?
As of September 2016, all three Hawaiian Electric Companies (HECO, MECO and HELCO) had reached the Public Utility Commission’s (PUC) Customer Grid-Supply program limit. Now, Hawaiians interested in installing rooftop solar will want to consider installing battery...
DERs take center stage at DistribuTECH
At the recent DistribuTECH Conference in San Diego, more than 13,000 attendees spent three engaging days discussing the biggest issues facing utilities today. One of the hottest topics, judging by session attendance and exhibit floor conversations, was Distributed...
2017: The year of the long range EV
In 2016, electric vehicle (EV) sales grew 37% and utilities initiated strategies for dealing with that growth. Six utilities and state energy agencies now use WattPlan® to provide customers with personalized and objective guidance to their EV related questions....
SolarAnywhere detects calibration error in nation’s most trusted ground site
How accurate are SolarAnywhere® irradiance data? They are accurate enough to identify an undetected calibration error at one of the nation’s most trusted ground truth stations. Figure 1 presents Direct Normal Irradiance (DNI) and Global Horizontal Irradiance (GHI)...
Utilities speed up interconnection with ePayments
There is a growing expectation among utility customers that interactions with their energy providers will take place digitally, online. This “digital transformation” is unlocking opportunities for utilities to streamline business processes and increase customer...

Choice, control and lessons from our auto industry friends
For software guys like us, 7:15 AM is a bit early for a presentation and test drive, but we couldn’t resist the chance to check out some of Ford’s latest electric vehicle (EV) and plug-in hybrid electric vehicle (PHEV) advances last week at their Power of Choice event...
CAISO addresses changing grid infrastructure
In a recent interview with Fierce Energy, President and CEO of the California Independent System Operator (CAISO), Steve Berberich, spoke about where CAISO is headed in 2013. As one of the largest electric grid operators in the United States, CAISO is responsible for...
Electric vehicles + solar: an idea whose time has come
You’ve likely heard about the partnerships springing up between electric vehicle (EV) manufacturers and solar (PV) system providers. Most recently, Honda and SolarCity announced a plan that allows Honda customers to install solar with a low upfront cost and see an...
Tilt vs. flat-mount PV: does it really matter?
Have you ever wondered if PV system orientation really makes that much difference to the amount of power produced by a PV system? As the map below illustrates, the answer is typically yes, but to varying degrees. This ‘Energy Gains’ map depicts how tilting solar...
Get smart about FiTs: get SmartFiT
As effective as FiT programs have been in promoting solar in countries such as Germany and Spain, they have sometimes become victims of their own success, leading to boom/bust cycles and political targeting. The SmartFiT is an alternative solution that has the...

Department of Energy’s aggressive fight against solar soft costs
Clean Power Research recently attended a U.S. Department of Energy workshop focused on solar soft cost reduction. We came away impressed by the DOE SunShot team’s clear focus on the right problem. While the cost of modules was once the dominant component of...
Top 2013 trends part 2: the NEM debate
Last week we identified the first of three big trends for the solar industry in 2013: soft cost reduction. This week, we look at the next big trend: a re-evaluation of net energy metering (NEM). While discussions about NEM aren’t new, they’ll be accelerating in 2013....
Valuing solar: a matter of perspective
2012 has seen a backlash against distributed generation net metering, particularly solar distributed generation. Most utilities in most states currently have some form of net metering, which is a simple mechanism for assigning a value to distributed generation that is...
