  • Colorado’s Roadmap to Reduce Greenhouse Gas Pollution Delivers Initial Results

    Colorado’s Roadmap to Reduce Greenhouse Gas Pollution Delivers Initial Results

    To deliver on the administration’s commitment to renewable electricity and bold action to reduce greenhouse gas (GHG) pollution across the economy, Governor Polis has directed state agencies to develop a comprehensive action plan during 2020 that expands upon the  Polis Administration’s Roadmap to 100% Renewable Energy By 2040 and Bold Climate Action released in May 2019.

    Under the direction of the Governor’s Climate Cabinet, several state agencies – the Colorado Energy Office, Department of Public Health and Environment, Department of Transportation, Department of Natural Resources and Department of Agriculture – are working with Energy and Environmental Economics (E3) to help develop a GHG Pollution Reduction Roadmap (Roadmap).

    The Roadmap will provide an action plan for the state to meet legislatively adopted, science-based targets for reducing GHG pollution 26% by 2025, 50% by 2030 and 90% by 2050 from 2005 levels. Initial work has helped to quantify GHG pollution in 2005 and project GHG pollution reductions from recently passed legislation and administrative actions. In future phases, the Roadmap will quantify projected reductions from near-term additional actions the administration is pursuing and will identify additional cost-effective legislative, administrative and regulatory actions, as well as voluntary measures to help achieve the state’s GHG pollution reduction goals. 

    The Roadmap evaluates the impact of 14 pieces of legislation the General Assembly passed in 2019 including establishing GHG pollution reduction goals, requiring local jurisdictions to adopt one of the three most recent versions of the International Energy Conservation Code (IECC), creating pathways to clean energy for electric utilities, modernizing the Public Utilities Commission, adopting new energy efficiency standards for appliances, and requiring investor-owned utilities to invest in electrifying transportation, as well as administrative actions including the adoption of zero emissions vehicle standard. In a presentation today at the Colorado Air Quality Control Commission, agencies shared initial modeling by E3 showing that currently adopted policies should allow the state to achieve an 18% reduction by 2025 and 25% by 2050.

    Will Toor, executive director of the Colorado Energy Office, said, “In only 14 months the Polis administration, working with the legislature, has made real progress on greenhouse gas pollution reduction. Our modeling shows that policies adopted through 2019 should allow the state to achieve two-thirds of our 2025 pollution reduction goals and half of our 2030 goals. This progress doesn’t take into account the additional reductions we expect to see once recent oil and gas legislation is fully implemented. But we are not done. In the near term, the administration is proposing rules to reduce emissions of hydrofluorocarbons, developing a new state electric vehicle plan, and working with legislators to make it easier for Coloradans to purchase electric vehicles, reduce building energy use and switch from burning fossil fuels in buildings to using clean electricity, as well as supporting legislation to back the use of renewable natural gas as a replacement for fossil methane. In the coming months, E3 will quantify the additional emissions reductions we can expect from these actions.”

    “About a year ago, Governor Polis gave us the directive to be bold in protecting the health of our communities and the Colorado environment by reducing greenhouse gases, and we have been running with that directive,” said Jill Hunsaker Ryan, executive director, Colorado Department of Public Health and Environment. “We are moving faster than ever because that is what needs to be done. We have adopted a car emissions standard to accelerate the transition from fossil fuel vehicles to zero-emitting electric vehicles; we have formed the first-ever climate change unit at the department, which is dedicated to reducing greenhouse gas emissions; we have enacted the initial round of rules to reduce oil and gas emissions under the stringent new law; and we are helping electric utilities plan to transition from coal power to renewable energy. We are only one year in and gaining momentum on the issue. The Roadmap assures that we are deliberate in the strategies we pursue.”

    There will be opportunities for Coloradans to provide feedback on the development of the Roadmap and actions that can help Colorado meet its GHG pollution reduction goals. To stay updated on the Roadmap process and submit feedback, go here

  • Colorado Energy Office Releases Study on Floating Solar Potential in the State

    Colorado Energy Office Releases Study on Floating Solar Potential in the State

    DENVER – The Colorado Energy Office (CEO) today released Colorado’s Statewide Potential Study for the Implementation of Floating Solar Photovoltaic Arrays. With the support of study lead Ciel & Terre and the National Renewable Energy Laboratory (NREL), CEO conducted a state-wide analysis of suitable water bodies to examine the potential for electricity production from floating solar photovoltaic systems.

    Floating solar photovoltaic (FPV) systems, also known as floatovoltaics, are an emerging application in which the most common components of traditional solar PV systems are mounted onto buoyant “floats.” These floats allow solar PV modules, wiring and electronics components to be sited directly on the surface of a body of water instead of on land or a rooftop. This floating application leverages the water surface that is typically viewed as an unused area for many non-recreational water bodies. Covering water bodies through various means, including FPV, has been shown to reduce evaporation and improve the local aquatic environment, presenting a unique multi-benefit opportunity. While Colorado could benefit from a reduction in evaporation from its lakes, ponds and reservoirs, the state’s climate – with large temperature swings and a variety of climate zones – also presents challenges for FPV systems which have had limited testing in extreme cold.

    Since the 2018 installation of a 75 kW FPV array in the Town of Walden, where multiple parties are closely monitoring the system’s performance and resilience to the harsh climate, FPV continues to attract the interest of stakeholders from both the energy and water sectors in Colorado. Following CEO’s work with the Walden project and a number of solar PV and water efficiency initiatives, the office conducted this study to better understand how FPV might align with Colorado’s diverse geography and ambitious clean energy and climate  goals.

    Using existing public datasets and satellite imagery, CEO identified nearly 6,000 potential sites for floating solar installations – 1,900 of which were rated as ideal. Through the application of NREL’s PVWatts® Calculator and using conservative coverage ratios on identified bodies of water, the study found FPV in Colorado has potential installed capacity exceeding 11,090 MW and resulting in annual electrical generation greater than 16,000 GWh. These conservative estimates present considerable electricity generation potential relative to Colorado’s existing electricity generation capacity and output, 69% and 32% respectively.

    “Governor Polis has adopted bold goals for renewable energy and climate action to transition from burning polluting fuels to widespread adoption of pollution-free electricity generation including wind and solar,” said CEO Executive Director Will Toor. “Floating solar is an important option for communities and utilities to consider as we collectively move toward this clean energy vision.”

    “This potential study helps electric utilities, developers and water body owners throughout Colorado better understand how floating solar might provide another means for meeting water conservation and renewable energy goals,” said Taylor Lewis, CEO Senior Program Engineer.

    The study is available for download here along with appendices that identify potential FPV sites by county and utility.
