Leadership

Our History

1997

Jeff Ressler
Founding the Company

Thomas Hoff, Ph.D., a Stanford graduate with a passion for renewable energy and photovoltaic (PV) economics, founds Clean Power Research as a research consultancy.

1998

From Research to Software

A neighbor asks Tom, “What is the value of solar to me?” To answer, Tom develops Clean Power Estimator® (now PowerBill® API), an online PV calculation tool that is rapidly adopted by utilities and PV manufacturers.

2000

Clean Power Research WattPlan Grid
PowerClerk Launches

To alleviate the challenges of paper-based incentive application processes in the face of rapidly growing volumes, Clean Power Research launches PowerClerk®. Designed specifically for utilities, PowerClerk automates and optimizes application workflows, reducing costs and processing time.

2007

Jeff Ressler
Software Services Group Is Formed

PowerClerk’s success leads to the creation of the company’s Software Services Group and marks a new focus on delivering adaptable, scalable and secure cloud software solutions to the energy industry. Jeff Ressler, a 10-plus year veteran of Microsoft, joins the company to run the new team, and the Kirkland, Wash., office opens.

2008

SolarAnywhere Launches

A partnership with the University at Albany (SUNY) and Dr. Richard Perez leads to the development of SolarAnywhere® Data, bankable irradiance data that is at the core of the current suite of solar data and intelligence offerings

2010

New PV Variability Method

In a paper published in the ISES journal Solar Energy, Clean Power Research shows that the relative power output variability of distributed PV fleets can be quantified. This insight helps in the management of existing PV fleets or designing new ones.

2012

Clean Power Research WattPlan Grid
SolarAnywhere FleetView Launches

SolarAnywhere® FleetView® launches to address the need for utilities and ISOs to cost-effectively and reliably integrate distributed PV into the grid. This allows for higher PV penetration and reduces costs for utilities, ratepayers and PV system owners.

2014

PowerClerk Interconnect Launches

Funded by a U.S. Department of Energy SunShot Initiative Incubator award, PowerClerk® Interconnect launches to help reduce solar soft costs by taking formerly paper-intensive interconnection processes online. The new PowerClerk platform provides utilities more control over their interconnection and DER program workflows to streamline processes for everyone involved.

2015

Clean Power Research WattPlan Grid
WattPlan Advisor Released

WattPlan® Advisor is developed to enable utilities to cost-effectively engage customers with highly-personalized answers to energy questions such as: “Is solar right for me?” Advisor incorporates newly available information such as interval data from smart meters and innovations like rate optimization to set a new standard for user-facing energy modeling tools.

2017

20th Anniversary

Clean Power Research celebrates 20 years providing innovative, efficient and adaptable software solutions that are helping to solve the energy industry’s most challenging problems.

2018

Clean Power Research WattPlan Grid
WattPlan Grid Launches

Clean Power Research and the Sacramento Municipal Utility District (SMUD) form a unique partnership to solve the critical challenge of utility DER planning. WattPlan® Grid is launched, a SaaS solution that addresses a range of challenges including load analysis, rate scenario testing and customer adoption propensity modeling.

2019

Data Visualization in PowerClerk

A new Dashboards feature for PowerClerk launches that enables program administrators to support program transparency with built-in reporting and data visualization capabilities—no export, programming or third-party tools required.

2020

Clean Power Research WattPlan Grid
evAPP Launches

The Electric Vehicle Analytics & Program Platform (evAPP™) is launched, giving utilities a new solution to manage EV programs end to end, including: engagement and enrollment, administration and automation, and EV adoption detection and modeling.
