Using Satellites to Determine Surface

Greenness

•Satellite data can help us

determine the current state

of the fuels across our service area

•The information is updated daily

Slide 16

We are using this technology to increase

our knowledge base about the weather and

how it impacts the electric system. We

provide the system operators with the

information intelligence to make better and

more informed operational decisions.

Using Weather Technology

SDG&E MesoNet Currently Operates 43 Pyranometers

Approximately 25 additional Locations through Sustainable Communities

Renewable Energy/Solar Forecasting

Solar Forecasting / Marine Layer Research

Power Generation Forecasting

Coastal Marine Layer Forecasting/Modeling

• Statistical Approach / Research

• Numerical Weather Prediction

Modeling past 50 years for wind, solar radiation, temperature in

conjunction with MeteoGroup

• Design of System

• Hardening Projects

• Support better understanding of Santa Ana Winds and Fire Potential

Acquiring Atmospheric Profilers • Improve monitoring and

short-term forecasting of the

marine layer

Solar Photovoltaic Power Generation Forecasting

Project Objectives:

Advance SDG&E’s understanding of long-term

benefits, determine solar forecasting

Integration requirements

Green Power Labs Project Deliverables:

Provide SDG&E with Day Ahead (DA) and

Hour Ahead (HA) Solar Power Forecasting

of 12 PV facilities

Our Current Operational Solar PV 1: ~120MW

Our Current Approved and Pending Solar 2: 1GW+

1. Current operational solar capacity provided by SDG&E operations.

2. Approved and Pending CPUC Interconnection Requests, solar PV and solar thermal. October 2011.

Slide 20

Coastal Marine Layer (CML)

Forecasting

Binary Logistic Regression Model

Binary Classification — Cloudy or Clear

Compartmentalize San Diego County into 1km grid, ~32,000 grid cells in region

Before the CML spatial and inland extent can be studied, each grid cell must be

quantitatively identified as cloudy or clear for each time step

Slide 21

Numerical Weather Prediction (NWP)

Next Steps

Data Assimilation (Surface & Satellite)

Increasing Resolution (Horizontal and

Vertical)

Increase computational capability

Start running high-resolution outputs of

solar radiation
