California’s Green Energy StandardRPS_03162016
To reduce the carbon footprint caused by utility-wide emissions, California’s Renewables Portfolio Standard was established by legislation in 2002. The mandate requires that all electric utilities procure energy generated by renewable resources into their portfolio. 

Subsequent amendments to the law have resulted in a number of changes to the RPS. Most notably, the October 2015 passage of SB 350 extends the timeline requirements to 2030, when 50 percent of each utility’s retail sales must come from eligible renewable energy sources. 

Interim renewable procurement targets: 

  • 20 percent of retail sales by Dec. 31, 2013
  • 25 percent of retail sales by Dec. 31, 2016
  • 33 percent of retail sales by Dec. 31, 2020
  • 40 percent of retail sales by Dec. 31, 2024
  • 45 percent of retail sales by Dec. 31, 2027
  • 50 percent of retail sales by Dec. 31, 2030

Meeting the green energy standard
A longtime proponent of renewable energy, IID has established targets through 2020 that meet or are slightly higher than the procurement targets listed above.

Located in a region with abundant sunshine, enviable geothermal capacity, wind and other renewable potential, IID has met or exceeded all RPS requirements to date, procuring renewable energy from diverse sources, including biomass, biowaste, geothermal, hydroelectric, solar and wind.

In its present position, IID expects to meet and exceed compliance period 2 targets and plans to procure additional resources as RPS goals rise.

Going forward
As IID looks to the future, it sees its renewable resources evolving. Within the last year, the district has taken steps to reduce its reliance on fossil fuel. At the same time, IID has entered into an agreement with a local geothermal energy producer to add more geothermal resources to its energy portfolio.

Furthering Renewable Growth
Utilities across the U.S. are scrambling to find additional sources of green energy to meet looming deadlines for renewable portfolio standards. With an abundance of renewable energy potential, the Imperial and Coachella Valleys are being looked as leaders in the green energy revolution.

Below is an illustration of the untapped renewable potential of the Imperial Valley.

 Resource Untapped in the Imperial Valley*  
 Geothermal  2,488 MW 
 Solar 28, 946 MW
 Wind 10,755 MW
 Bio Mass       94 MW
 Total Potential Capacity 42,283 MW
Several factors including the market price of electricity, demand for renewable power, tax credits, transmission capacity and other incentives given to generators will greatly affect the amount and timing of the development of the above noted resources.

According to a 2008 feasibility study sponsored by IID, it will be cost effective for generators to develop as much as 1,969 MW of renewable energy by the year 2016. This is made up primarily of 1,682 MW of geothermal and 216 MW of wind. This growth would bring more than 7,000 new construction and operation/maintenance jobs to the Imperial area. Several factors will influence the realization of this potential including policy and politics of the renewable industry, the market price of electricity, trend/costs of renewable power and most importantly the ability of generators to get their product to market.

Renewable Energy Feasibility Study – Conducted by Summit Blue Consulting, LLC January 2008 [PDF]

In support of IID's goal to become a better steward for resources in its control area, in 2011 IID requested a Geothermal Resource Assessment of its lands in the Imperial Valley. Aerospace Corporation (“Aerospace”) and their subcontractor, Clear Creek Associates, performed a geothermal resource assessment using the following information:

1. Airborne hyperspectral imagery from the Spatially Enhanced Broadband Array
Spectrograph System (SEBASS);

2. Satellite Based Advanced Spaceborne Thermal Emission and Reflection Radiometer
(ASTER) Imagery;

3. Publicly-available reports and geologic and hydrogeologic data.

In 2013, IID  asked EES Consulting (EES) to develop a feasibility study for revenue potential from land leases in the Imperial Valley for renewable energy projects. IID is interested in helping to develop renewable energy resources in the Salton Sea area that would partially fund the restoration of the Salton Sea. IID has asked EES to estimate the revenue potential available to help fund the Salton Sea Projects. Initially, IID would like to know if there is enough economic potential in the Imperial Valley at the Salton Sea to substantially help fund Salton Sea restoration projects. This report reviews renewable project potential and provides a conceptual analysis of the revenue potential available both to IID and to fund the Salton Sea
Projects.
