Overview: Pathways to Commercial Liftoff
Pathways to Commercial Liftoff represents a new DOE-wide approach
to deep engagement between the public and private sectors.
The initiative’s goal is catalyzing commercialization and
deployment of technologies critical to our nation’s net-zero goals.
Pathways to Commercial Liftoff started in 2022 to:
• collaborate, coordinate, and align with the private sector on
what it will take to commercialize technologies
• provide a common fact base on key challenges (e.g., cost
curve)
• establish a live tool and forum to update the fact base and
pathways

Key Messages for Innovative Grid Deployment
Shifting to a proactive, future-oriented approach for managing and investing in the T&D grid is critical to
ensure system reliability in a rapidly changing energy future
Inaction is not an option – communities and utilities that fail to modernize the grid in the near-term will struggle
to provide reliable and affordable power, threatening human well-being and economic development
opportunities
The existing T&D grid footprint is a powerful resource that can be unlocked with multiple readily-
available, innovative technologies and applications that can be quickly scaled today
These innovative grid solutions are technically-proven and commercially-available – yet deployment and
associated industry know-how is lagging due to a lack of sufficient industry incentives and prioritization
Four technologies* in focus for today are high-priority for rapid scaling: dynamic line rating (DLR), advanced
conductors, high voltage direct current lines (HVDC), and Advanced Distribution Management Systems
(ADMS) and its advanced applications
Utilities, regulators, policymakers, solutions providers, and other key stakeholders can start acting today,
taking advantage of unprecedented federal investment & policy incentives to accelerate deployment of
innovative solutions that can unlock meaningful near-term value
*Analysis of the remaining technologies will be included in the full Liftoff report

Grid pressures (not exhaustive)
Notes: *From NREL’s 100% Clean report, upper load growth bound is based on NREL’s accelerated demand electrification scenario (ADE), which assumes an aggressive electrification of end-uses; load growth is closer to ~30-35% in NREL’s
LTS scenario that assumes higher end-use energy efficiency; in DOE’s National Transmission Needs Study, load growth of 40% by 2040 is modeled in a moderate load growth/high clean energy growth scenario. **Based on an expected 20-35
GW of annual distributed generation additions from 2025-2030; additional capacity from BTM storage and EV capacity are additional DERs expected, but not included in this estimate. ***~6x increase in wind & solar capacity based on NREL
LTS scenario (higher-end use efficiency) that drives ~1200-1400 GW; ~10x increase in wind & solar capacity based on ~2 TW wind & solar needed for a 100% clean grid by 2035. ****An additional 200% increase in interregional transmission
capacity needed by 2040; ~64% increase (representing an incremental ~55 TW-mi) is the median within-region transmission capacity expected based on a moderate load growth & high clean energy growth scenario; in a high load growth and

Yet investing in innovative grid solutions remains challenging
“We are focused on keeping the current system up and running. It is hard to prioritize advanced
technologies when we need to maintain the old system today.”
- Electricity Cooperative
“We are piloting these new technologies but scaling them is a challenge because traditional solutions are
usually the cheapest and easiest option to address immediate needs. Even if we did look at the longer-term
there isn’t a standard process for how to quantify the long-term value for these grid mod technologies.”
- Large Investor-Owned Utility
“The rate case process was designed for physical poles and wires that would last decades – not
software that might be outdated in a few years. With a process that was designed 100 years ago,
it’s hard for PSCs be as quick and agile as the needs of today demand.”
- Former PUC Commissioner
“Utilities are very risk averse and hesitant to adopt new technologies. Our regulatory and
business models were all designed around reliability and limited risk taking, so it can be hard to first
justify investments and then overcome organizational hurdles to actually deploy a new technology.”
- Large Investor-Owner Utility
“Commissioners are concerned about anything that raises ratepayer costs. Our teams are
under-resourced as it is, so it’s hard to understand if this new tech is necessary or just raises rates.”
- Former PUC Commissioner

DLR | Dynamic Line Rating (DLR) improves the utilization of the existing
T&D system to increase effective system capacity
Source: WATT Coalition
Definition Value Proposition Key Barriers
• DLR is a real-time calculation of a
power line’s thermal capacity (effectively
power current capacity) based on local
environmental and weather conditions
• Grid operators can use real-time dynamic
rating to manage power flows, better
utilizing existing system
• Without DLR, grid operators use
conservative static ratings to determine
T&D power flows – often underutilizing a
line’s true capacity
• Increases effective T&D capacity on
existing ROW (~10-30%+)
• Avoids challenges of new T&D builds (e.g.,
permitting, cost, time)
• Relieves system congestion, reduces
curtailment, and improves interconnection
• Real-time capacity rating vs. static and
ambient adjusted ratings alternatives
• Cost-effective capacity enhancing
solution (typical payback period of
<1-6 months in congested areas)
• Easy to implement without outages
(typically <3-12 months to implement)
• Supports improvements to system
reliability, efficiency, and planning
• Lack of investment incentives
under traditional models (e.g., low
CAPEX, utility incurs cost while
benefits largely accrue to customer)
• Technology misperceptions and
limited awareness (e.g.,
performance reliability & quality,
implementation process)
• Changes to operational practices
required to integrate DLR
• Lack of industry standards for
testing and certifying DLR
performance
Capacity increase of 10-30% based on average DLR outcomes; potential for greater capacity increases of >40-55%+ in some locations based on industry experience

Utility: National Grid (NY/IOU, 2022)
Location: Western New York
Motivator: Wind curtailment
Solution: Install DLR (LineVision
sensors) on two 30-mile 115 kV
transmission lines
Expected benefits:
• Reduce wind curtailment by 350 MW
• Expand transmission corridor's
capacity by 190 MW
• Strategic approach to DLR alongside
Tx capacity upgrades brought down
total cost
DLR | DLR is a mature technology that has been deployed in the US (and
widely overseas) to address congestion and unlock Tx capacity
Note: DLR has been deployed widely across Europe (ex: Belgium deployed DLR across 28 high voltage lines in 2008, driving 5-20% increase in ratings, 30% increase in current, and 10% increase in
import/export capacity while resolving congestion issues and increasing renewables deployment)

Utility: Pennsylvania Power & Light (PA,
IOU, 2023)
Location: Pennsylvania
Motivator: Congestion costs
Solution: Install DLR sensors on two 230-
kV lines
Expected benefits:
• $50M in costs vs. alternatives
considered (new build, reconductoring)
• $23M annual congestion cost savings
• ~18-19% capacity increase on "normal"
lines, 9-17% on "emergency" lines
• One line had congestion costs in
2011/22 and 2022/23 winters decrease
from $60M to $1.6M
Utility: Oncor (Electric Delivery
Company, 2014)
Location: Texas
Motivator: Reduce line congestion
Solution: Install DLR on 8 lines ranging
from 138 to 345 kV
Realized benefits:
• ~6-14% increase line rating above AAR
• 5% additional capacity relieved 60%
congestion; 10% capacity relieved
100% congestion
• $4.8M installation cost addressing
$349M in congestion costs

US congestion costs are rising DLR is an available and underutilized solution
• DLR can reduce and/or eliminate congestion (~60-
100% congestion reduction found in previous deployments)
• Cost-effective method to increase effective transmission
capacity and mitigate congestion costs (DLR payback
periods of <1-6 months)
• Easy to implement on individual systems without outages
• Proven technology ready for increased deployment with
multiple successful US and international deployments
DLR is a high-impact opportunity to increase effective transmission capacity and reduce congestion,
lowering energy bills for ratepayers
Federal funding (e.g., GRIP) is available to help address implementation hurdles and accelerate deployment

Advanced Conductors | Reconductoring with advanced conductors can
increase line capacity & improve efficiency – but higher cost is a concern
Definition Value prop Key barriers
• Category of T&D lines that are made
from higher-performing materials
• Typically, composite-based core
(e.g., aluminum composite core
(ACCC)) with high strength and high
temp resistance (limited sag)
• Higher line capacity may require
upgrades to supporting equipment
(e.g., substations)
• Cost-effective solution to double
T&D capacity on existing ROW
• Avoids cost, time, and permitting
challenges of new T&D builds
• Higher energy efficiency due to
lower electrical resistivity
• 20-40% lower energy losses reduces
ratepayer and overall system costs (e.g.,
reduced need for peak generation)
• Reduced sag improves reliability
during severe weather events (e.g.,
high temperatures, heavy snow/ice,
high winds) due to greater strength-to-
weight ratio
• Higher upfront costs vs.
conventional ACSR/ACSS
conductors harder to justify in
least-cost investment models
(~2-4x higher CAPEX*, but lower
OPEX)
• Traditional models do not
holistically value or incentivize
full benefits for ratepayers (e.g.,
energy efficiency)
• Implementation challenges due to
new installation practices that
require training field crews and a
need for greater standardization
across advanced conductor
technologies and accessories
Note: ACSR = Aluminum Conductor Steel Reinforced; ACSS = Aluminum Conductors Steel Supported ; ACCC = Aluminum Conductor Composite Core
*Additional costs from associated equipment upgrades (e.g., expanding substation capacity) to handle higher ampacity can further increase initial costs, though these investments may already be required due to
standard repair and replacement costs required to manage aging grid infrastructure.

HVDC | HVDC systems increase capacity while providing reliability and
resiliency solutions to the grid
HVDC system includes:
• Efficient and high-capacity direct
current (DC) transmission links
(e.g., long distance overhead lines,
underground cables, or submarine
cables)
• Converter stations connecting
HVDC links to the AC system (primarily
Voltage Sourced Converters (VSC) for
modern HVDC projects)
• Increased Tx capacity with limited
energy losses over long distances,
underground, or underwater
• Market optimization capabilities
(e.g., congestion mitigation, usage
control)
• Improved system reliability from
greater active and reactive power
control to support AC grid (e.g.,
dampening oscillations, regulating
voltage, power control)
• Provides contingency event
support (e.g., emergency energy
imports at high ramp rates, black
start and system restoration
capabilities)
• Global supply chain bottlenecks
increasing HVDC project uncertainty,
timelines, and costs
• Greater technical standardization
needed for HVDC integration (e.g.,
VSC-HVDC standards)
• Multi-stakeholder collaboration
needed to ensure buy-in and
successful project execution
• Current investment processes do
not value holistic system benefits of
HVDC vs. HVAC alternatives
• Typical challenges for new, large-
scale Tx builds (e.g., permitting,
ineffective cost recovery, fragmented
transmission planning, long timelines)

HVDC | Stimulating domestic HVDC demand will incentivize U.S. based
manufacturing and grow domestic supply chains
Global HVDC transmission line length source note: IEA 2023; Electricity Grids and Secure Energy Transition, https://iea.blob.core.windows.net/assets/ea2ff609-8180-4312-8de9-494bcf21696d/ElectricityGrids

Rising global demand is outpacing manufacturing
capacity – creating global supply chain challenges
Building domestic supply chains is an opportunity to
secure HVDC inputs – but requires a strong demand signal
• Limited domestic supply chain capacity due to
low HVDC demand historically
• Higher risk of project uncertainty and failure if
overdependent on already strained foreign markets
• Clear demand signal and industry collaboration
is necessary to incentivize supply chain build out
and protect future US demand
Accelerating HVDC projects can create a strong demand signal to drive domestic
manufacturing build out, with public funding (e.g., GRIP, LPO, 48C tax credits) available
to support HVDC projects and component manufacturing
3x demand surge since
2010 causing supply
chain bottlenecks (e.g.,
7+ years for HVDC
converter stations)

ADMS | ADMS (and advanced ADMS applications) is the cornerstone Dx
Operational Technology system for efficiency, reliability and resilience
• ADMS is a software platform that
integrates several sub-systems
• ADMS base typically integrates SCADA,
outage mgmt., and data mgmt. systems
• ADMS is the enabling technology
platform for other advanced applications:
• VVO: distribution system optimization
• FLISR: reliability and
resilience improvements
• DERMs: connects large-scale and
BTM distribution energy resources
• Provides situational awareness to
improve Dx system operational
efficiency by enhancing system
visibility in real-time
• Increases resilience and reliability
by improving ability to withstand or
recover from a disruption quickly and
with minimal customer interruption
• Increased data granularity to better
inform maintenance and investment
decisions
• Enables additional system value
(e.g., capacity, decarbonization,
reliability) through unlocking
advanced applications
Sources: Modern Distribution Grid Project (DOE), Guidehouse Insights
Definition Value prop Key barriers
• Significant shift in grid management
approach is required to operate an
automated ADMS system vs. legacy
manual approach
• Technically and operationally
complex to implement -- including
sufficient IT systems to support ADMS
components and several pre-requisite
technologies (e.g., sensors, comms
equipment, data)
• Current investment processes
typically do not account for holistic
set of benefits realized over longer
period (10y vs. 3y traditional
investments, situational awareness is
not a typically monetized benefit)

ADMS | Public funding can help de-risk complex ADMS investments;
following emerging best practices can support successful deployments
• Time investments (e.g., sensor installs, software upgrades)
during existing equipment replacement and change-
outs to support system integration and reduce costs
• ADMS can either supplement or replace existing
systems so can be flexibly deployed to maximize value
• Identify opportunities for quick wins, modularly deploying
and phasing in ADMS across the system
• Define a stepped or incremental path to operationalization
• Ensure organizational buy-in and vision alignment to
desired capabilities
• Incorporate non-traditional benefits into business case
(e.g., situational awareness, cost avoidance, faster outage
response times)
• Take a long-term view: ADMS is often cost effective when
evaluated over a 10-year horizon (incl. advanced applications)

Barriers to and solutions for modernizing the existing T&D grid
SolutionsBarriers
1
Limited common understanding of and standard
methodologies to holistically evaluate innovative grid
technologies
Development and adoption of standardized methodologies to
evaluate multi-value and long-term oriented solutions
Capacity building among regulatory bodies to understand grid tech
2
Traditional utility and regulatory incentive structures do
not align with the needs of a modern grid – particularly
lacking monetization for avoided costs and improved
performance and disincentivizing innovation
Updating regulatory and utility business models to reward and value
performance (incl. for costs of avoided events) instead of CAPEX,
enable new risk and cost sharing models, and encourage innovation
3
Updating existing market assumptions and SOPs (e.g., at RTO
level) to integrate advanced grid control solutions and appropriately
incentivize grid resources
Operational and implementation complexity slowing
adoption (e.g., organizational change required; changes to
standard operating processes – incl. at utility, regulator, and
RTO level; technology integration with existing systems)
Proactive utility organizational transformations to align operating,
investment, and planning practices with modern grid management and
innovation
4
Competing priorities and uncertainty on how to
strategically plan investments (e.g., prioritization strategy,
tech sophistication needed, stranded tech assets concerns)
Shifting to long-term oriented integrated regional planning
processes with coordination across stakeholders (utilities,
regulators, policymakers, communities, solutions providers, RTOs)
5
Technology maturity concerns, particularly for some
advanced adaptive control grid solutions
Greater transparency and information sharing, especially for operational
demonstrations of earlier stage tech; increased investment to improve
quality of available solutions with solution providers sharing tech risks
DRAFT. PRELIMINARY. UNDER ONGOING DEVELOPMENT.

Recap: Key Messages for Innovative Grid Deployment
Shifting to a proactive, future-oriented approach for managing and investing in the T&D grid is critical to ensure
system reliability in a rapidly changing energy future
Inaction is not an option – communities and utilities that fail to modernize the grid in the near-term will struggle to
provide reliable and affordable power, threatening human well-being and economic development
opportunities
The existing T&D grid footprint is a powerful resource that can be unlocked with multiple readily-available,
innovative technologies and applications that can be quickly scaled today
These innovative grid solutions are technically-proven and commercially-available – yet deployment and
associated industry know-how is lagging due to a lack of sufficient industry incentives and prioritization
Four technologies* in focus for today are high-priority for rapid scaling: dynamic line rating (DLR), advanced
conductors, high voltage direct current lines (HVDC), and Advanced Distribution Management Systems
(ADMS) and its advanced applications
Utilities, regulators, policymakers, solutions providers, and other key stakeholders can start acting today, taking
advantage of unprecedented federal investment & policy incentives to accelerate deployment of innovative
solutions that can unlock meaningful near-term value
*Analysis of the remaining technologies will be included in the full Liftoff report
