WHAT IS SYSTEM OPTIMIZATION?
Electricity system optimization means
making the most effective use of a
portfolio of electricity resources to
maximize top public policy goals…
…delivering a system that is:
Reliable
Affordable
Clean

WHAT ARE OUR OPTIONS TO OPTIMIZE?
I. What technologies can help optimize the grid?
II. What are the barriers to system optimization and how can we overcome them?
III. What can State Energy Offices do to address and overcome these barriers?

OPTIMIZING THE RESOURCE MIX:
SUPPLY-SIDE TECHNOLOGIES
Utility-scale wind and solar are now cost competitive with conventional generation

OPTIMIZING THE RESOURCE MIX:
EFFICIENT GRID MANAGEMENT
• Advanced Metering & Data Mgmt.
• Smart Thermostats
• Automated Demand Response
• In-line Voltage Regulation
• Thermal/Chemical Storage
• Smart Charging
• Load-shaping Energy Efficiency

and how can we overcome them?

BARRIERS TO SYSTEM OPTIMIZATION
CURRENT REGULATORY MODELS
POWER MARKET DESIGNS
POLICIES

BARRIERS TO SYSTEM OPTIMIZATION
Example: Cost of Service Regulation
Revenue =
Operating Costs + (Capital Spend)*(ROR)
As utility investment increases . . .
Revenue increases.

OVERCOMING BARRIERS:
CHANGING INCENTIVES
Align financial incentives of:

FROM: “Did we pay the right amount for
what we got?”
TO: “Are we paying for what we want?”

Models for the
Modern Era

Change the central question…
OVERCOMING BARRIERS:
PERFORMANCE-BASED REGULATION

• Reliable service
• Customer satisfaction
• Equity
• Innovative third-party
services
• System-wide least cost
• Resource diversity
• Effective facilitation of

• Environmental perf.

OVERCOMING BARRIERS:

22
All resources should compete as equals to provide:
Energy
Capacity (if traded)
Ancillary Services
Begin trading important services like:
Flexibility
Ramping
OVERCOMING BARRIERS:
MARKET DESIGN FOR OPTIMIZATION
23
A state could choose to create a “distribution system optimizer”
This entity could be:
A properly incented utility
A nonprofit similar to the ISO/RTO
Either way, an Integrated Distribution Plan can help
OVERCOMING BARRIERS:
DISTRIBUTION SYSTEM OPTIMIZATION

III. What can State Energy Offices do to promote
technology and policy solutions?
25
EVERY STATE IS DIFFERENT…

State Energy
Offices
Markets
Planning
State Energy Offices can use a handful of important tools in different
market structures to enable the resources we need to optimize the
system.
POLICIES FOR SYSTEM OPTIMIZATION
27
PLANNING-BASED OPTIMIZATION POLICIES:
INITIAL STEPS
Encourage—or host—dialogue among utilities, commissioners, legislators, governors’ offices, and stakeholders about how to take advantage of new technological opportunities.
Promote adequate budget and support for the PUC to explore these issues.
Fund pilot programs for new technologies (consider partnering with national labs or DOE), Take advantage of state-owned buildings as testing grounds.
28
PLANNING-BASED OPTIMIZATION POLICIES:
TRANSFORMATIVE
Build system optimization into the core of state energy plans and attendant state energy policies.
Create a roadmap for regulators and utilities to move toward performance-based regulation tied to overall societal goals for the power system.
29
MARKET-BASED OPTIMIZATION POLICIES:
INITIAL STEPS
Study the costs and benefits of improving market product definitions, including local job creation, energy affordability, reliability, and environmental performance.
Study the costs and benefits of expanding or linking existing markets with neighboring markets – perhaps first through an energy imbalance market.
Open bidding for small amounts of new grid capabilities like “flexibility,” and see what bids in.
Engage with other State Energy Offices to increase regional coordination and trading.
30
MARKET-BASED OPTIMIZATION POLICIES:
TRANSFORMATIVE
Join new markets and/or consolidate balancing areas.
Create an actionable roadmap for improving market structure and transparency in the state.

Later this month, NGA will release an RFP for interested states to apply for:
Tailored briefings and technical assistance
Funding for an in-state summit
A three-day workshop including state team time
Quarterly webinars and monthly team calls
The latest research on utility business models
