OUTLINE 
• Residential Water-Energy-CO2 optimization 
model. 
 Household minimize their bills and conservation costs 
facing water and energy price shocks. 
• Utility-scale hourly Water-Energy simulation 
model. 
 Based on actual data we build a model that can simulate 
demand changes. 
3
RESIDENTIAL END-USE OPTIMIZATION MODEL 
• Based on a previous water-energy- 
GHG assessment 
study. 
• Using probability 
distribution functions based 
on a water end-use survey. 
• 10,000 MC simulations for 
10 different cities in CA.

DEMAND: CONSERVATION ACTIONS

• Each household has a set of available actions: 
– Long-term: Retrofits. 
– Short-term: Behavioral. 
• Each action has: 
– Cost. 
• Annualized costs for retrofits. 
• Hassle costs on a daily basis for behavioral changes. 
– Effectiveness (Water or energy savings).

• Subject to: 
– Decision variables are binary 
– Savings are less than initial use (upper bound) 
– Mutually exclusive actions 
– Interdependence among actions 
11
Results: Adoption rate and water savings for long-term actions 
12
Results: Adoption rate and energy savings for water-related actions 
13
Results: When energy cost is included 
(respect the only-water scenario) 
14 
• Adoption rate: 
• Retrofit shower: +7.9% 
• Retrofit clotheswasher: +1.7% 
• Reduce shower length: +3.2% 
• … 
• Increased savings: 
• Indoor water savings: +24% 
• Energy savings: +30% 
• GHG savings: +53%
Results: Demand function and elasticities 
15
Results: Own- and cross-price 
elasticities (averages) 
16 
• Water own-price elasticity Ɛww = -0.05 
• Energy own-price elasticity Ɛee = -0.03 
• Energy water-price elasticity Ɛew = -0.02 
• Water energy-price elasticity Ɛwe = -0.004 
• Own-price values are relatively low. 
• Water price affects energy consumption more than energy price 
affects water use. 
• Literature about cross-price elasticities reviewed: Only 1 paper!! 
Lars Garn Hansen (Land Economics, 1996) obtained a Ɛwe = -0.2, 
but none obtained Ɛew.
UTILITY-SCALE HOURLY WATER-ENERGY SIMULATION MODEL 
• Based on a real data from 
EBMUD water utility. 
• We select a only a part that 
represents 27% of total 
EBMUD water use. 
• We want to simulate real 
operation to obtain results 
for different scenarios.

• Annual water use: 17,604 MG/year 
• Annual energy use: 558,000 MWh/year 
• Energy Intensity: 31.7 MWh/MG 
• Water utility energy cost: $3,355,451
Simulating scenarios 
21 
• Scenario 1: Residential optimal conservation 
• Annual water use: 16,541 MG/year (-6%) 
• Reduction Energy Use: 36,940 MWh/year (-6.6%) 
• Water utility energy savings: $115,493 (3.5%) 
• GHG savings: 7023 metric tons / year (93.5% 
residential and 6.5% Utility)
Simulating scenarios 
22 
• Scenario 2: Peak shaving 
• Outdoor consumption shift to off-peak hours 
• The same water and energy use (but different 
hours) 
• Water utility energy savings: $51,023 (1.5%) 
• Energy utility benefits: ??? But some!
TAKE HOME MESSAGES 
• Increased water (and water-related energy 
and GHG emissions) conservation when 
energy is included. 
• Most of water-related energy is from water 
heating in households. 
• There are gains for water and energy utilities 
working together.

AGU2014: Coupling residential end use and utility water energy models

  • 1. COUPLING RESIDENTIAL END USE AND UTILITY WATER-ENERGY MODELS by Alvar Escriva-Bou, Jay R. Lund, Manuel Pulido-Velazquez, Edward Spang and Frank Loge ALVAR ESCRIVA-BOU alesbou@gmail.com @alesbou notjustwater.wordpress.com AGU 2014 FALL MEETING SAN FRANCISCO, DECEMBER 15TH 2014

  • 3. OUTLINE • Residential Water-Energy-CO2 optimization model.  Household minimize their bills and conservation costs facing water and energy price shocks. • Utility-scale hourly Water-Energy simulation model.  Based on actual data we build a model that can simulate demand changes. 3
  • 4. RESIDENTIAL END-USE OPTIMIZATION MODEL • Based on a previous water-energy- GHG assessment study. • Using probability distribution functions based on a water end-use survey. • 10,000 MC simulations for 10 different cities in CA. 4
  • 5. Water The economics behind the model: Demand Energy Uo Indoor hot water Indoor cold water Outdoor water Air conditioned Appliances Space heating Water heating Complementarity 0 1 2 qw0 qw2 qw1 qE1 qE0 qE2 5
  • 6. DEMAND: CONSERVATION ACTIONS 6 • Each household has a set of available actions: – Long-term: Retrofits. – Short-term: Behavioral. • Each action has: – Cost. • Annualized costs for retrofits. • Hassle costs on a daily basis for behavioral changes. – Effectiveness (Water or energy savings).

  • 12. Results: Adoption rate and water savings for long-term actions 12
  • 13. Results: Adoption rate and energy savings for water-related actions 13
  • 14. Results: When energy cost is included (respect the only-water scenario) 14 • Adoption rate: • Retrofit shower: +7.9% • Retrofit clotheswasher: +1.7% • Reduce shower length: +3.2% • … • Increased savings: • Indoor water savings: +24% • Energy savings: +30% • GHG savings: +53%
  • 15. Results: Demand function and elasticities 15
  • 16. Results: Own- and cross-price elasticities (averages) 16 • Water own-price elasticity Ɛww = -0.05 • Energy own-price elasticity Ɛee = -0.03 • Energy water-price elasticity Ɛew = -0.02 • Water energy-price elasticity Ɛwe = -0.004 • Own-price values are relatively low. • Water price affects energy consumption more than energy price affects water use. • Literature about cross-price elasticities reviewed: Only 1 paper!! Lars Garn Hansen (Land Economics, 1996) obtained a Ɛwe = -0.2, but none obtained Ɛew.
  • 17. UTILITY-SCALE HOURLY WATER-ENERGY SIMULATION MODEL • Based on a real data from EBMUD water utility. • We select a only a part that represents 27% of total EBMUD water use. • We want to simulate real operation to obtain results for different scenarios. 17

Assembling the model Water users Water utility 19 Total Annual Water Use Energy Utility Hourly water demand Hourly water supply Water-related energy GHG Emissions Shares of use by customer category Indoor vs. Outdoor Hourly distribution of end uses Irrigation Necessities (P-ET) Pumping and treatment patterns Water regulation Water treatment Pumping and distribution Wastewater treatment Water-related energy Regressions and pumping patterns End-uses energy intensity
  • 20. Some Results: Energy break down 20 • Annual water use: 17,604 MG/year • Annual energy use: 558,000 MWh/year • Energy Intensity: 31.7 MWh/MG • Water utility energy cost: $3,355,451
  • 21. Simulating scenarios 21 • Scenario 1: Residential optimal conservation • Annual water use: 16,541 MG/year (-6%) • Reduction Energy Use: 36,940 MWh/year (-6.6%) • Water utility energy savings: $115,493 (3.5%) • GHG savings: 7023 metric tons / year (93.5% residential and 6.5% Utility)
  • 22. Simulating scenarios 22 • Scenario 2: Peak shaving • Outdoor consumption shift to off-peak hours • The same water and energy use (but different hours) • Water utility energy savings: $51,023 (1.5%) • Energy utility benefits: ??? But some!
  • 23. TAKE HOME MESSAGES • Increased water (and water-related energy and GHG emissions) conservation when energy is included. • Most of water-related energy is from water heating in households. • There are gains for water and energy utilities working together. 23
