Environmental footprint


PROTECTING NATURAL RESOURCES Environmental stewardship is one of our six core principles. We address issues important to us and our stakeholders — protecting and restoring habitats, improving air and water quality and responsibly managing our properties.


Greenhouse gas and air emissions


As PGE develops solutions to meet our customers’ energy needs, we’re protecting the environment and combatting climate change by emitting less carbon dioxide (CO2


).


AVOIDING CARBON EMISSIONS TODAY During the past 10 years, PGE has taken actions that help us avoid emitting almost 1.5 million tons of CO2


These include: • Energy efficiency: Thanks to our partnership with


Energy Trust of Oregon, our residential customers use about 20 percent less energy per year than the national average (see chart below).


• Wind and solar: In 2013, PGE generated 167 average megawatts of electricity from wind and 2 average megawatts from solar resources, which produce zero CO2


emissions (see chart below).


• Plant efficiency upgrades: We make investments that increase electricity production without building new plants, and we make improvements to our carbon-free hydropower facilities.


• Climate Trust payments: We fund CO2 reduce our carbon emissions.

customer load served. We’re able to achieve a downward trend over time as we cease coal operations at our Boardman, Ore., plant and as more of our customer needs are met by energy efficiency, wind and solar.


In 2013, our thermal generation plants and purchases emitted 0.39 tons of CO2

* We partner with Energy Trust of Oregon to help drive energy efficiency with our customers. This chart shows cumulative energy-efficiency gains from Energy Trust of Oregon programs since 2003. These programs help customers curb energy use and reduce PGE system loads.


**The wind and solar power we generate fluctuates due to the variability of these renewable resources, but it is increasing over time as we add more wind and solar generation facilities. The majority of PGE’s renewable energy generation comes from wind.
