Pilot Project Gets Solar Panels in Sync with Electric Vehicle Chargers

January 9, 2020 in Energy Systems, Transportation & Fuels Author: Maggie Kristian

What if we could harness the energy produced by the sun and maximize its potential to power electric vehicles (EVs) with zero-carbon electricity? That’s exactly what GPI has been working on in a pilot project that studies how managed EV charging can pull varying levels of power from the solar panels on our rooftop based on how much solar is being produced at a given time. This ability to use “solar synchronization” could have big implications for reducing carbon emissions in both the electricity and transportation sectors, and presents potential benefits for consumers and businesses alike.

Analysis: Rooftop Solar Can Provide Year-Round Electricity—Even in the Bold North

December 19, 2019 in Energy Systems, Transportation & Fuels Authors: Dane McFarlane, Elizabeth Abramson

When it comes to solar energy, a common question is how electricity generation will be affected by seasonal shifts or daily changes in the weather. These variations become especially important when households and businesses consider using rooftop solar panels to serve their electricity needs, such as for charging electric vehicles (EVs). By analyzing a full year of data collected from the solar array on the Great Plains Institute’s own rooftop, paired with the electric vehicle chargers at our building, we have gathered insights to answer to this question.

Approval of Xcel Energy’s Electric Vehicle Pilots Highlights Key Considerations for Electric Utilities

December 12, 2019 in Energy Systems, Transportation & Fuels Author: Trevor Drake

Following a stakeholder engagement process facilitated by the Great Plains Institute in 2018, Xcel Energy received approval and is moving forward in Minnesota with new electric vehicle (EV) pilot programs.

As investor-owned electric utilities seek to meet the needs of shareholders, consumers, and the environment, EVs offer a unique opportunity. If implemented carefully, utility investments in EV infrastructure and programs can provide a series of benefits, including new sources of utility revenue, better services for EV drivers, reduced costs for all consumers by making the electric system more efficient, and reduced pollution and greenhouse gas emissions.

Engaging Communities on Utility-Scale Wind & Solar Development in the Midwest: Part III, Local Readiness and Decision-Making

December 10, 2019 in Communities, Energy Systems Authors: Jenna Greene, Jessi Wyatt

Community-scale readiness is critical to the successful development of the Midwest’s abundant solar and wind energy resources. As utility-scale wind and solar development increases in the Midwest, communities should consider how renewable energy development aligns with local goals and values. A series of proactive actions can ensure that the way utility-scale renewables develop in a community is in line with community vision, reduces potential conflict, and optimizes co-benefits.

GPI Goes to the Movies: The Current War

November 26, 2019 in Energy Systems Authors: Katelyn Bocklund, Maggie Kristian

On occasion, Great Plains Institute (GPI) staff like to venture into the world of pop culture, especially when that pop culture has to do with our favorite topic—energy. Some GPI staff attended the recent film The Current War, which dives into the origins of our modern electric grid system and the inventors, investors, and engineers that made it happen. Two of our staff members shared some thoughts about that battle over who would create the modern electric grid and the critical work ahead to transform the grid for a low-carbon future.

Solar Energy & Natural Systems: Exploring Co-Benefit Opportunities

Solar projects can be designed and sited to meet natural resource conservation goals. Capturing the natural resource co-benefit opportunities of solar development will involve creative partnerships, targeted spatial planning, and rethinking site and project design. Continue reading »

Engaging Communities on Utility-Scale Wind & Solar Development in the Midwest: Part II, Local Considerations

October 7, 2019 in Communities, Energy Systems Authors: Jenna Greene, Jessi Wyatt

The lowering cost of wind and solar energy generation has a local impact: communities are going to see more wind and solar development projects, more often. Communities see many of the direct impacts from these developments, from tax revenues to opportunities for co-beneficial land uses to managing resident feedback on such development. Many local considerations and indicators can help communities understand opportunities for maximizing local co-benefits as the market continues to increase for utility-scale solar and wind development.

Q&A: Home Efficiency Upgrades Bring Savings & Unexpected Benefits

October 2, 2019 in Energy Systems Author: Lola Schoenrich

Improving the energy efficiency of your home is a win-win-win. It makes your living space more comfortable, saves you money, and is good for the environment. Leading analysis shows that energy efficiency can significantly reduce energy use and is a critical tool for reaching emissions reduction targets. In the US, the residential and commercial sectors account for about 30 percent of energy use (which represents almost all of energy use in buildings), with the residential sector accounting for about 16 percent of that total.

Approval of a Wisconsin Transmission Project Marks a Major Milestone for Clean Energy in the Midwest

September 11, 2019 in Energy Systems Authors: Matt Prorok, Rolf Nordstrom

In 2007, a bipartisan group of seven governors announced ground-breaking energy and climate agreements that would go on to shape the region’s energy system. Over a decade later, Wisconsin regulators recently approved the capstone transmission project, the last in a set of 17 “multi-value transmission projects” (MVPs) across the region representing $6.5 billion in investment that grew out of those original agreements. The MVP portfolio’s 17 projects will enable over 16 GW of wind generation to come online, delivering 52 million megawatt-hours (MWh) of energy throughout the MISO footprint through 2031. Put another way, without these lines, over 60 percent of the renewable energy needed to meet the region’s renewables goals through 2031 would have been curtailed. Continue reading »

e21 Forum Highlights Four Areas of Energy Innovation Across Minnesota

September 10, 2019 in Energy Systems Author: Trevor Drake

Minnesota energy stakeholders came together at the end of August to learn about four areas of innovation happening across the state’s energy system. The event was put on by the e21 Initiative, a collaborative effort between the Great Plains Institute and Center for Energy and Environment that convenes diverse stakeholder groups to help shape and advance a decarbonized, customer-centric, and technologically modern energy system in Minnesota.
