The Schatz Energy Research Center was a major presence at the 5th Global Off-Grid Solar Forum and Expo, which took place this week in Hong Kong. The conference is the premier global event for the off-grid solar industry. Schatz Center Director Arne Jacobson was on the conference organizing committee, and six members of the Center’s off-grid team delivered presentations and facilitated discussions in conference sessions and side events over the three-day meeting.

The Schatz Center’s involvement in the conference is linked to its leadership role in the World Bank Group’s Lighting Global Quality Assurance Program, the world’s leading framework for quality assurance and consumer protection for off-grid solar products. The quality assurance program is widely used to support consumer protection for low-income families in off-grid areas of Africa, Asia, and the Pacific Islands.

The Center’s work on Lighting Global is carried out in partnership with CLASP, a D.C.-based non-profit, and it involves close collaboration with the Global Off-Grid Lighting Association (GOGLA).

Blue Lake Rancheria microgrid wins Project of the Year Award at DistribuTECH conference

The Blue Lake Rancheria (BLR) microgrid was awarded the 2018 Project of the Year Award for Distributed Energy Resources (DER) Grid Integration at the annual DistribuTECH conference held this week in San Antonio, Texas. The award was given in recognition of the project’s ingenuity, scope, practicality, vision, and follow-through.

The Schatz Energy Research Center at Humboldt State University is the project lead and system integrator. The BLR microgrid integrates a photovoltaic array, a Tesla battery, and a legacy backup generator. A Siemens management system and foundational programming developed by Schatz engineers control the microgrid, which provides renewable electricity, lowers the Rancheria’s energy costs, and supports clean energy jobs. The microgrid also provides an emergency services backbone for its remote rural community and equips the Rancheria to serve as a Red Cross shelter in the event of a natural disaster.

DER design strategically deploys power generation across multiple sites to lower impact on existing grid infrastructure and to make use of renewable technologies including solar and wind. By locating power generation close to where that power will be used, utilities are able to streamline infrastructure improvements. When microgrids are employed, these smaller generation sites can disconnect from the main grid in the event of a grid outage – protecting critical electricity supply within a campus, business, hospital, or other community facility.

The BLR microgrid was funded by the California Energy Commission’s Electric Program Investment Charge and the Blue Lake Rancheria Tribe. Major project partners include Pacific Gas & Electric, Siemens, Tesla Energy, Idaho National Laboratory, GHD Inc., Colburn Electric, REC Solar, McKeever Energy & Electric, and Kernen Construction.

Announcing the Donald and Andrea Tuttle Fellowship for Clean Energy Studies

The Schatz Energy Research Center is pleased to announce the Donald and Andrea Tuttle Fellowship for Clean Energy Studies at Humboldt State University. The Tuttles have established this annual fellowship as part of an effort to tackle the challenges posed by climate change, and to reduce its impacts on humanity and ecosystems. The fellowship will support graduate students in Environmental Systems who intend to research or conduct project work in renewable energy, energy efficiency, or related areas in the clean energy field.

The Tuttle Fellowship will provide $15,000 in financial support for one academic year. The recipient is also eligible to be employed on research projects at the Schatz Center (typically, quarter-time throughout the academic year). The fellowship may be renewed once, based on performance and at the discretion of Schatz Center directors and the selection committee, for a second year of study.

The Tuttle joins two fellowships already associated with the Schatz Center: the Blue Lake Rancheria Fellowship for Clean Energy Studies and the Schatz Energy Fellowship. Current year fellows are working with Center projects in off-grid energy access and smart grid technologies. Jimento Aikhuele and Anamika Singh are involved with the Center’s quality assurance project on solar system installations at public facilities in Nigeria and Niger; Aikhuele’s associated thesis is on the use of renewable energy technologies to prevent maternal and infant fatality. Steven Shoemaker is conducting a benefits analysis of the recently deployed Blue Lake Rancheria microgrid, which was recognized this fall by the US Federal Emergency Management Agency for energy resiliency, while Thalia Quinn is working on the Center’s new “Solar+” distributed generation project.

Schatz Energy in brief: climate-smart infrastructure and sustainable bioenergy

The Union of Concerned Scientists just released a new white paper on “climate-smart” infrastructure in California, citing the Blue Lake Rancheria (BLR) microgrid as a prime example of infrastructure built to safely sustain communities during climate change.

The Roundtable on Sustainable Biomaterials (RSB) adopted a revised Standard for Advanced Fuels this month at the delegate meeting in Vancouver, Canada. Kevin Fingerman (second from left below) is an RSB board member, and is the principal investigator on the California Biopower Impact Project here at the Schatz Center.

A Quality Assurance Framework for Solar System Installations at Public Facilities in West Africa

The Schatz Center and the ECOWAS Centre for Renewable Energy and Energy Efficiency (ECREEE), with support from the World Bank through their Lighting Africa program, are working collaboratively with government partners in Nigeria and Niger to develop a new approach for the procurement, installation, and long-term maintenance of off-grid solar electricity systems at public facilities, such as health clinics, schools, police posts, public offices, and water pumps.

Off-grid solar systems offer the promise of clean, renewable electricity for public facilities. However, historically, there has been a high failure rate for these systems in many countries, often caused by poor quality design and installation, or lack of maintenance and good operational practices following installation even when initially high quality system components are installed.

The proposed new approach involves the innovative use of digital remote monitoring technology, along with quality standards for equipment, design, and installation, to ensure and verify the ongoing performance of off-grid solar electricity systems. Under such an approach, companies in the off-grid solar sector could enter lease agreements or extended service contracts with government agencies to provide an agreed-upon level of electricity service in return for guaranteed monthly payments. The payments could be designed to cover the capital costs of equipment and installation (or a percentage of these costs), along with the ongoing operation and maintenance costs over the projected system life. By digitally monitoring the performance of the systems, a third-party could verify that the service provider is delivering the agreed electrical service and instruct the government agency to pay the monthly fee. Spreading the cost of the systems over many years and keeping service providers engaged is expected to improve the long-term performance of the systems.

Over the next two years, the proposed approach will be developed, evaluated, and revised through research and deployment of approximately fifteen pilot systems in Nigeria and fifteen pilot systems in Niger. Our main role in this effort is to develop the quality assurance framework that serves as the basis for the approach. This includes determining a standard for service delivery that can be used to verify that the system’s performance matches contractually specified targets. Our staff will conduct site visits, provide technical designs for the thirty pilot systems, and verify system performance for the first six months. Support for this effort is provided by the World Bank Group’s Lighting Africa Program.

To kickoff the project this September, three team members visited sites in Niger and Nigeria to gather initial information about health clinics, schools and other public facilities. Chris Carlsen, a Center alumna and current consultant, met with officials in Niger and visited several communities to understand the country’s existing infrastructure. Jimento Aikhuele, a Schatz Energy graduate fellow originally from Nigeria, and Olakunle Owoeye, a Center consultant, met Chris in Nigeria to scope out potential sites for pilot installations and learn about the energy needs of the various facilities. The team also visited sites with existing solar installations to gain insight into why well-intentioned solar systems so often fail. Our initial work in the field was fruitful thanks to the indispensable support of ECREEE, the Ministries of Energy, Health and Secondary Education of Niger, and the Ministry of Power, Works and Housing of Nigeria.

Back at the Schatz Center, we have been hard at work reviewing existing standards and determining appropriate requirements to include in the quality assurance framework. This work dovetails with projects we’ve conducted in the past, including the ongoing development and co-management of the Lighting Global Quality Assurance program. We are looking forward to heading back into the field to gather more information before finalizing a draft of the framework and providing recommended designs for the pilot installations next spring.

Sustainable Futures Speaker Series: Scaling up renewable power in Humboldt County – Nov 9

Join us on Thursday, November 9 at 5:30 pm in Founders Hall 118 for the final session in this semester’s Sustainable Futures Speaker Series. A panel of energy experts will explore the opportunities and challenges of scaling up renewable power in Humboldt County, through questions such as:

  • If we want to support expanded use of renewable energy, should we prioritize purchasing low cost renewable power from outside the area or generating renewable power locally?
  • How might our relative isolation impact the sale of locally generated renewable energy to the Western grid?
  • How do we balance our critical need for rural resilience with investment in renewable sources such as wind and solar?
  • To what extent is our local grid infrastructure ready to support distributed generation?

Moderator Arne Jacobson (Director, Schatz Energy Research Center) will be joined by Matthew Marshall (Executive Director, Redwood Coast Energy Authority), Antoine Peiffer (Lead Engineer, Principle Power), Jon Stallman (Integrated Grid Planner, Pacific Gas & Electric) and Dave Carter (Managing Research Engineer, Schatz Center) for this forward-looking discussion about clean energy strategies for the north coast.

This speaker series is intended to stimulate cross-disciplinary discussion, debate, and collaboration around issues related to energy, the environment, and society. The series is sponsored by the Schatz Center, the Environment & Community Graduate Program, and the College of Arts, Humanities & Social Sciences at Humboldt State University.

Solar Plus: Improving Performance in Distributed Clean Energy Systems

This fall, we are kicking off a new “Solar Plus” (Solar+) project to investigate how real-time coordination between clean energy systems can yield performance improvements that benefit both building owners and utility operations. Research and development over the past decade has successfully reduced the cost of solar arrays, batteries, building controls, and electric vehicles. Many of the emerging challenges we now face are related to the large-scale deployment and integration of distributed clean energy components. For example, electrical distribution circuit capacity is limited (in order to prevent power lines from overheating), which in turn limits the downline capacity of distributed generation systems. This Solar+ project will develop control strategies to coordinate onsite resources to reduce their combined footprint on the power system, effectively increasing the capacity of the grid to host clean energy technology.

Our pilot site is a gas station and convenience store at the Blue Lake Rancheria (BLR) in Blue Lake, California. Convenience stores typically have sizable loads, including HVAC and refrigeration, which require backup power. Many of the sites also have significant potential to host rooftop solar. By working with a very common building type (there are 12,000 convenience stores in California alone), we can design with replication in mind.

Over the next two and a half years we will design and install a Solar+ system at the BLR and measure the value of distributed energy coordination. Our project will develop: (1) a hardware design guide for integrated Solar+ packages, (2) open-source software for controlling the technology, and (3) guidelines to determine the best locations for investment, given local insolation and onsite potential for system coordination. Our outcomes will be focused on integrating solar, batteries, and advanced building controls into packages that are market ready and can make positive impacts on the future trajectory of California’s built environment.

This project is funded by the California Energy Commission through the Electric Program Investment Charge (EPIC) program. Our key partners are the Blue Lake Rancheria, which owns the gas station, and Lawrence Berkeley National Lab, where a team of researchers is developing open-source “Solar+ Optimizer” software.

Project partners also include Southern California Edison, whose refrigeration system test center data is helping us to develop algorithms, and Pacific Gas & Electric, the local energy utility.
