EE maximizes uses, reduces GHG emissions, creates jobs New EE goal is unachievable without including To-Code Savings in EE Programs. State needs to shape Policies to increase EE Savings. 6 Codes & Standards: The Driver of Energy Efficiency and Zero Net Energy From Technology Conceptualization to Code Compliance Aggressive aspiration goals for Zero Net Energy (ZNE) All Residential New Construction by 2020 All Commercial New Construction by 2030 50% of existing buildings to be retrofit to ZNE by 2030 As codes advance, above-code becomes difficult to justify 7 De-Carbonizing Electricity: Natural Gas Stationary Use Pathways
The move toward nearzero emission technology focuses on: Distributed Generation Community-scale Generation Matched with Renewables Power Generation with Carbon Capture Not just Solar and Wind Fuel Cells Micro-turbines Combined Heat & Power De-Carbonizing the Pipeline: Renewable Natural gas WHATS POSSIBLE POWER 2-3 million homes Convert waste from dairies, farms and landfills
CH4 into biogas using anaerobic digestion extract the methane put in the pipeline for future use REPLACE 75% of all diesel used by CA vehicles When used for transportation, Biogas from food and green waste can actually REMOVE GHGs from the atmosphere SOURCE: Bioenergy Association of California, CARB May 2014 Look-Up Table30
De-Carbonizing the Pipeline: Power-to-Gas excess renewable energy goes through electrolysis which splits the molecule hydrogen & carbon combine through methanization carbon captured from factories and plants methane can be stored in the pipeline for future use SoCalGas Facilitating Cleaner Energy Options for Our Customers

Europe to date German Energy Agency on Power-to-Gas: System Solution DENA Website (German Energy Agency) With the Power-to-Gas Strategy Platform, the Deutsche Energie-Agentur GmbH (dena) the German Energy Agency and its partners are supporting the use and development of the Powerto-Gas system solution. CAISO (on the Duck Curve) steps must be taken to mitigate over generation risk. These steps include increasing exportsand requiring renewable generation curtailment. The ability to export power depends on the needs of neighboring entitiesthe resource mix would also benefit from resources with energy storage capabilities E3 Study: Integration of New Low/Zero Carbon Options
Expands upon 2012 Science article Strategic use of gaseous fuels supports near- and long-term goals In nearer term, opportunities for efficiency, near zero technology and new uses for natural gas (transportation) In medium- to long-term, new lowcarbon sources of gas need development and introduction 17 Pipeline de-carbonization works together with electrification towards Climate Change objectives Pipeline de-carbonization offers Cost Effective and Resilient Pathways
De-carbonization can play an important role Integrating Variable Renewable Generation Resources Pipeline de-carbonization reduces emissions in sectors that are otherwise difficult to electrify, including heavy duty vehicles; residential and commercial end uses, and industrial end uses Managing Energy Grid (gas and electric together) = efficiency and cost avoidance Senate Bill 350 Clean Energy and Pollution Reduction Act of 2015 (Sen. Kevin de Leon) Expands upon 2012 Science article Purpose: Create jobs, grow the states economy, and improve public health by setting new standards for Californias Renewable Portfolio Standard, reducing petroleum
use, and increasing energy efficiency in existing buildings. Original Legislation: Called for doubling the existing energy efficiency goals SoCalGas Position Doubling of goal is unachievable without key policy changes Amendments SoCalGas lobbied to include substantive EE policy changes, including: Allowing for to-code customer incentives and energy savings Ensures that customers receive the incentive payment amount that was committed throughout the project Allows for pay for performance energy efficiency programs Continued Gaps Amended language was removed that would ensure equal treatment to all EE program administrators
Amended language was removed that would create a more advantageous energy efficiency costeffectiveness methodology 18 Shaping Policy to Increase EE Savings Expands upon 2012 Science article Challenge: CPUC policy generally limits customer incentives to above-code savings. Tougher for customers to participate in EE programs. The standards gap between existing buildings and code requirements is widening. Governor's goal is unachievable without including To-Code Savings Current incentives are not enough for customer participation SoCalGas is working with stakeholders to improve energy efficiency program policies: CPUC authorized IOUs to implement a To-Code Pilot SoCalGas has lobbied for amended language that incorporates EE policy changes Joint Party Proposal 19
