SolarAnywhere FleetView Forecasts Top EPRI Study

EPRI_SolarForecastTrial_Fig1_720X600

The Electric Power Research Institute (EPRI) recently completed a solar forecasting trial designed to help utilities understand the value that accurate solar prediction can bring to their energy market schedules and balancing operations. SolarAnywhere® FleetView® fared well in the trial, displaying the highest levels of accuracy in its PV generation…

Attention DER/PV interconnection teams: Your system planners are relying on you!

2017-08-16_Attention-system-planners-DER-PV-interconnection-teams-need-your-input_Table1

Recently I spoke with two very large investor owned utilities (IOUs) that are trying to backfill information for thousands and in some cases tens-of-thousands of PV systems located in their service territories. In other words, these system planners do not have equipment specifications for distributed energy resources (DERs) on their…

Evidence of satellite-truth when comparing to ground irradiance measurements

2017-07-27_Toubleshooting-Ground-Measurements-WithSA_Figure1

Troubleshooting ground measurements with satellite irradiance data We recently reported how the use of SolarAnywhere® Data made it possible for us to detect an unreported irradiance sensor calibration issue at one of the nation’s most trusted reference stations: the SURFRAD station of Fort Peck, Montana. We also reported in a…

The August 21st solar eclipse: How and where it’ll impact solar production

2017-06-21_Solar-Eclipse-Impact-Solar-Production_-Figure-1

On August 21, 2017, the U.S. will experience a solar eclipse for the first time since May 2012. The eclipse will cause an obscuration of the sun’s light, resulting in a reduction of the energy from irradiance that will hit the Earth’s surface. As the eclipse crosses the U.S., it…

Adapting utility processes to the reality of distributed PV

Figure1-Utility-Systems-and-Processes-Affected-by-Distributed-PV

Utility processes and systems impacted by distributed PV In previous blog posts, we’ve looked at how the growth of distributed PV can impact grid operation at the system level. These blogs addressed how distributed PV can lead to the often referenced “duck curve,” and how SolarAnywhere® FleetView® software can be used…

What is the value of accurate solar forecasting for utility-scale PV plants?

2017-03-08_What-is-the-value-of-accurate-solar-forecasting__Fig1

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 generation is variable in nature. Being able to predict solar…

DERs take center stage at DistribuTECH

DERs-take-center-stage-at-DistribuTECH_Figure-1

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 Energy Resource (DER) forecasting and management. DERs are disrupting the utility business…

SolarAnywhere detects calibration error in nation’s most trusted ground site

SACalibratesSURFRAD_Fig1

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) measured at the Fort Peck, Montana SURFRAD station and satellite-based SolarAnywhere GHI…
