NASA researchers have participated in American Society of

Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE)

meetings and in its Meteorology and Climate subcommittee.

Sample datasets were made available for evaluation by committee

members. These datasets specifically address unmet data needs

for clear-sky solar flux information for the building design

community.

Climate change impacts

In the energy market forecasting and climate change

impacts community, integrated assessment models are

increasingly used to assess policy options for climate

change mitigation and adaptation. The US Pacific

Northwest National Laboratory’s (PNNL) MiniCAM

market forecast model is one such integrated assessment

model. MiniCAM has a detailed representation of energy

technologies for energy supply and end use. NASA has

provided surface solar energy datasets specifically

designed to meet input needs of MiniCAM’s renewable

energy module. The impact of the NASA inputs is

currently being evaluated and we plan to provide addi-

tional datasets for use by MiniCAM and other integrated

assessment models.

The Program conducted a stakeholder’s workshop in

early 2007 which engaged other US Government agen-

cies, electric power utilities, and the private sector to

understand user requirements and assess how NASA-

derived measurements could meet some of these needs.

Stakeholders expressed a strong interest in understanding

future climate change impacts, especially considerations

such as land use, temperature, and reducing uncertain-

ties in forecasts to enable adoption and mitigation. The

Program will begin assessing the utility of downscaled

global climate model predictions to inform regional

climate change impacts in the Energy sector.

Space weather impacts

Enhanced solar activity can cause disruptions to electric

power transmission systems. A notable example was the

major X-class solar flare on 13 March 1989, and its resul-

tant geomagnetic disturbance which led to instability in

Hydro-Quebec’s electric power grid, leaving six million

people without power for nine hours. The Energy

Management Program has partnered with the Electric

Power Research Institute’s (EPRI) SUNBURST network

to enhance its capability for predicting geomagnetically

induced currents (GIC) and their impacts on the power

transmission system using NASA observations of the near-

Earth environment (including the Solar and Heliospheric

Observatory (SOHO), Solar Terrestrial Relations

Observatory (STEREO), Advanced Composition Explorer

(ACE), Wind and Geotail) together with a suite of models

that predict the ground-based impact of these solar distur-

bances. SUNBURST predictions may be used by electric

power companies to better predict the potential for

damaging GIC events.

By developing data products using NASA spaceborne

measurements and model predictions in close cooperation

with decision makers, using consistent units, and deliv-

ered in easy-to-use interfaces, the NASA Applied Sciences

Program Energy Management application advances the

uptake of Earth observations and models to improve deci-

sion-making in the Energy sector worldwide. The Program

works closely with the Group on Earth Observations

(GEO) Energy Community of Practice to ensure that our

activities are aligned with GEO Energy work plan goals to

improve the management of energy resources.

NASA’s spacecraft constellation monitoring the Earth-Sun system

Observations from many of these spacecraft have been used to inform

decision making in the energy sector by providing Earth radiation, solar, and

near-Earth environment datasets

Geomagnetically induced current events

Power systems in areas of igneous rock (grey) are the most vulnerable to

the effects of intense geomagnetic activity because the high resistance of

igneous rock encourages geomagnetically induced currents (GICs) to flow

in the power transmission lines situated above the rock. (Left) Shown in

cross-hatching are the auroral zone and the extremes that the aurora can

reach during severe disturbances such as 13 March 1989. (Right) NASA

provides solar and near-Earth environment data sets used by models to

predict GIC events
