disruptive challenges in electricity
Disruptive challenges in electricity
  • Demand side:
    • “negawatts” or energy efficiency (EE)
    • Smart grid related technologies / networked homes
  • Demand & supply side: demand response (DR)
    • Flattens peak demand
    • Firms variable renewable energy sources
  • Supply side: Distributed generation (DG)
    • Increasing role of renewable energy in supply mix
    • 3rdparty suppliers of rooftop solar
cause policies driving energy efficiency negawatts
Cause: Policies driving energy efficiency (“negawatts”)
    • Regulatory policies
      • Fixed cost recovery mechanisms/decoupling (27 states). In Michigan, DTE has a revenue decoupling mechanism.
      • Performance incentives (23 states). DTE has a performance incentive for EE in Michigan (earn up to 15% or program spending if energy savings targets exceeded)
    • Energy efficiency resource standards (EERS). In Michigan, 1% for electric utilities in 2012 and beyond.
  • Energy codes and national appliance/equipment standards becoming more stringent

Cause: Smart grid technologies driving energy management (EE, DR, DG)
  • Smart meter deployment (networking customers)
    • 40 million deployed; 65 million expected by 2015
    • In Michigan, about 866,000 smart meters deployed as of EOY 2012. Over 1 million expected by EOY 2013 (about 50% of DTE electric customers).
  • Networked customers opens door to possibilities
    • Energy management and demand response
    • Smart technologies in home or business; smart appliances
    • Smart charging of EVs

Effect: Energy efficiency flattens energy consumption growth in the US (IEE forecast based on AEO 2012 reference case)

growth in renewable energy in us
Growth in renewable energy in US
  • How much can renewable energy contribute to future U.S. electricity supply.
    • AEO forecast of 16% by 2040 is too conservative.
    • NREL Renewable Electricity Futures Study (2012) shows 80% renewable energy by 2050 possible in the U.S.
  • With DR and storage, electric power system can accommodate higher levels of variable generation from wind and solar?
  • In recent past, high growth in wind energy. Now at 3%.
  • Now, high growth in solar PV expected. Now at 1%. Could grow to 3% by 2016.
cause 1 policies and pricing driving dg
Cause 1. Policies and pricing driving DG
  • 29 state plus DC have RPSs, 17 with mandates/programs for solar and other DG
  • Net metering in 43 states
  • Feed-In Tariffs – adopted/proposed in a few states (common in Europe)
  • Reverse auction mechanism (CA & CT)
  • Subsidies, rebates, tax incentives, financing.
  • Zero net energy goals
  • Critically important to price DG right - cost of access to grid; cost of energy (e.g., Virginia standby charge)
is solar dg becoming a disruptive technology
Is solar DG becoming a disruptive technology?
  • Annual PV installations grew 76% in 2012 in US, reaching 2,816 MW (2.8 GW)
  • Greentech media forecasts 30% growth in US market in 2013
  • Cumulative 2012 solar capacity in US: 6,175 MW (6.2 GW)
  • Cumulative solar capacity in US projected to be 28 GW by 2016
    • [28,000 MW/1,171,000 MW] = 3% of total US capacity

possible scenarios and effects
Possible scenarios and effects
  • Outcomes
    • Utilities lease rooftops and own solar PV
    • Disintermediation: 3rdparty owns solar PV and sells contract to customer
    • Customers own solar PV
is solar pv the wireless technology for the electric power sector
Is solar PV the “wireless” technologyfor the electric power sector?
  • Wireless transformed telecom sector
    • Decline in landlines (traditional cash cow for telecom)
    • Wireless developed in places without landlines
  • DGtoday
    • So far, DG is not utility owned (utilities own large solar PV)
    • Top states today: CA, AZ, NJ
    • Subsidies galore
  • What is the biz model for DG?
    • Own solar panels and lease rooftops – comm, resi
    • Combined business – solar DG and efficiency and utility supplied power. Is this a regulated or non regulated business?
