Will U.S. Natural Gas Pipelines Get a Piece of the Government’s $1 Trillion Pie?

by Christina Nagy-McKenna, Enerdynamics Facilitator

The Trump administration has sounded the horn: It wants to strengthen United States’ Washington Money.infrastructure to the tune of $1 trillion. Highway projects, bridge projects, water and energy infrastructure projects — the list of needs is long and the corresponding price is hefty. Many in the energy industry hope some of the proposed infrastructure investment money comes their way.

Gas pipeline companies are already linking shale fields to parts of the East where capacity is tight and winter supply prices are vulnerable to severe price spikes. More is needed, they say, particularly in New England where memories of the winter price spikes of 2014 and 2015 are still fresh. Clean energy advocates are hoping to see new electric transmission lines get built and integrate with renewable projects that reduce the industry’s carbon footprint. The urgency to do both of these is further driven by the closure of coal and nuclear power plants and the christening of new natural gas-fired power plants in their place.

Who pays for new natural gas and electric transmission lines is still up for debate as is exactly how the financing will come together. Officials within the new administration have mentioned tax incentives to stimulate infrastructure spending and possible public-private partnerships. In the regulated utility world, distribution and transmission companies historically have recovered costs from their utility ratepayers, however a recent Massachusetts Supreme Court ruling flatly turned down the idea that electric rate payers fund a natural gas pipeline project.

The August 2016 decision put an immediate chill on Spectra Energy’s (now Enbridge) Access Northeast pipeline project. The expansion of the Algonquin pipeline and new LNG storage was to provide enough gas to make 5,000 megawatts of power. After the Supreme Court ruling, utilities Eversource and National Grid pulled out of the project as did four additional area utilities. Enbridge will continue to try build the project, but the uncertainty of the pipeline’s funding has slowed progress.

The Access Northeast pipeline project uncovered another issue: the tension between those who believe that more natural gas pipelines are needed and those who believe that no new pipelines should be built and that demand side management (DSM) is the key. In this case, Attorney General of Massachusetts Maura Healey not only disagreed that the electric utilities interested in the Access Northeast project should pass the costs onto their customers, she also questioned the need for more natural gas pipeline capacity in the area. She commissioned a research study, “Regional Electric Reliability Options Study,” that found the region could maintain current reliability standards until 2030 without making infrastructure changes. The study also found that demand response programs and energy efficiency programs would help reduce customer demand while keeping customer risk low.

Other pipeline projects making recent headlines include:

  • TransCanada’s Keystone Pipeline and Energy Transfer’s Dakota Pipeline projects —  Both projects faced intense public protests before being issued permits by the new administration. Even though both pipelines were meant to ship oil, there is a concern in the natural gas industry that its pipelines may be subject to increased environmental scrutiny simply because they too are pipelines like Keystone and Dakota.
  • Dominion Energy’s Atlantic Coast Pipeline —  Federal Energy Regulatory Commission (FERC) staff determined this project should move forward even though it will mean impacts to the surrounding environment. Opponents do not believe that mitigation measures will make up for the damage, and others have questioned whether the 1.5 Bcf/day of natural gas is necessary. This tension between those who would build and those who would preserve the environment will likely continue.


Ultimately, pipeline projects that can show they are necessary and in the public interest will likely be built regardless of the new administration’s $1 trillion plan. So far in 2017, before it lost its quorum, FERC certified 7 Bcf/d of pipeline capacity. This is in addition to the 17.6 Bcf/d of pipeline capacity it certified in 2016. FERC certification does not guarantee that a pipeline will be built, thus the industry will need to continue to be aware of environmental, regulatory, and customer issues.

Utility of the Future: Recent Study’s Six Key Findings

by Bob Shively, Enerdynamics President and Lead Facilitator

Electric utilities across the world are working diligently to identify new business models Ener_GOF_w_Header_4-11-17.pngthat will provide success in such a future world. Then each must begin the arduous task of implementing the models in a typically slow-moving industry.

To assist utilities in this task, the MIT Energy Initiative (MITEI) recently released the study Utility of the Future. The study was based on more than two years of primary research and analysis on how the provision and consumption of electricity services is likely to evolve over the next 10 to 15 years. According to the report authors, the study “aims to serve as a guide for policy makers, regulators, utilities, existing and startup energy companies, and other power-sector stakeholders to better understand the factors that are currently driving change in power systems worldwide.”

The study highlights six core findings:

    • Prices and regulated charges for electricity services must be dramatically improved: Locational time-based pricing should replace existing flat, volumetric tariffs. Grid injections and withdrawals should be priced the same regardless of time and place. They also support peak-based capacity charges that “unlock flexible demand and distributed resources and enable significant cost savings.” Lastly, MITEI recommends that care be taken in applying social goods and other network charges with the risk that inefficient grid defection may occur. To facilitate such pricing, all consumers and producers will need Advanced Metering Infrastructure (AMI).


    • Regulation of distribution utilities must be improved: Forward-looking, multi-year revenue requirements with profit-sharing mechanisms for cost-savings investment and operations will result in better outcomes for consumers and market participants. This includes equalizing financial incentives related to capital and operational expenditures so that utilities are not incented to build infrastructure when other solutions are more cost-effective. And, MITEI supports use of outcome-based performance incentives and incentives for longer-term innovation.


    • The structure of the electricity industry should be evaluated to minimize potential conflicts of interest: “Network providers, system operators, and market platforms constitute the critical functions that sit at the center of all transactions.” In the future, maintaining a data hub or data exchange is likely to become a fourth key function. Properly assigning responsibilities for these functions is critical. MITEI suggests that it is best if the entity or entities responsible for system operations and system planning are financially independent of competitive market participants. Without financial independence, strong regulatory oversight is necessary.


    • Wholesale market design should be improved to integrate distributed resources and create a level playing field for all technologies: Services traded in wholesale markets need to be updated to reflect the operational realities and new distributed resources as well as the new ways that conventional power plants are operated on systems with a high level of renewable and/or distributed resources.  Markets needing updates include capacity mechanisms, day-ahead and real-time markets, and payments for operating reserves and other ancillary services.


    • The importance of cybersecurity and privacy protections will continue to increase: Robust regulatory standards for cybersecurity and privacy must be developed and implemented across all sectors of the electricity network.


    • Better utilization of existing assets and more optimal energy consumption: Use of DERs for optimizing the system holds great potential for cost savings, but market participants must also be aware of potential for uneconomic deployment of resources if rate or market signals are improper.


Since the value of some electricity services varies significantly by location on the grid, it is “impractical to define a single value for any distributed resource.” Locational pricing will allow resources to be located in the right spot on the grid for highest value and unlocking this value can be an efficient alternative to traditional generation, transmission, or distribution investment. Due to economies of scale, widely distributed deployment of many technologies may be inefficient in some locations, but this may continue to change as new innovations transform the economics of any given application.

It’s clear that the future world envisioned by MITEI is far from where most utilities are today. To assist with the transformation, the last 18 pages of the study are devoted to a toolkit for regulators and policy makers. The electric industry must prepare for yet another huge market transformation. MITEI’s Utility of the Future study is a good reference manual to envision how the industry is likely to evolve.

A Typical Day at an ISO (Independent System Operator)

by Bob Shively, Enerdynamics President and Lead Facilitator

To prepare for an operating day, the independent system operator (ISO) must schedule units one day ahead of time to kansas_city_2_lprovide supply across the upcoming 24 hours. This is handled by the day-ahead scheduling process. Units are scheduled hourly, meaning that units will receive 24 schedules – one for each hour of the following day. The schedule tells the unit what services it is expected to provide and the amount of megawatts (MW) associated with each scheduled service.

For instance, for a given hour a unit with a capacity of 200 MW might have 150 MW scheduled to provide energy and 50 MW scheduled as spinning reserves. This tells the unit operator that for the given hour, it is expected to provide 150 MW of energy and must be prepared to ramp up an additional 50 MW if called on by the ISO.

Day-ahead Scheduling

The day-ahead process works as follows:

  • At a specified time in the morning, unit scheduling coordinators submit an offer to the ISO. This offer includes services the unit is willing to provide at a given price as well as various operational characteristics such as start-time, ramp capability, willingness to be started and then stopped, and minimum and maximum run times.
  • Simultaneously, load-serving entities (LSEs) submit hourly bids for buying energy to supply loads. Although LSEs sometimes state an unwillingness to buy energy above a certain price level, in most cases LSEs simply state a forecast load plus a willingness to pay whatever the price is to receive supply.
  • The ISO inputs expected system conditions including transmission availability and then runs optimization software to determine the least-cost dispatch available to serve the required loads given the various generation offers.
  • By the early afternoon, the ISO sends out schedules to each unit that was selected in the optimization process and notifies other generators that they have not been scheduled. The ISO also notifies all LSEs of the amount of load scheduled to be served. The optimization model creates day-ahead energy prices for each location on the grid and zonal prices for ancillary services. The energy prices are called locational marginal prices, or LMPs, and reflect the actual marginal cost of serving load at each location.
  • Since day-ahead schedules are considered firm, units are paid the LMP for their scheduled output, and loads are charged the LMP for their scheduled deliveries regardless of what actually happens in real time.
    day-ahead scheduling

Real-time Operations

A separate group at the ISO runs the system to ensure that supply and demand are kept in balance in real time during the operating day. This process works as follows:

  • The real-time operators have various units available to ramp up or down given the resources selected in the day-ahead scheduling process.
  • As the supply-demand balance fluctuates, the ISO ramps units as needed based on the offers accepted in the day-ahead. A real-time LMP is determined based on the price for marginal units used in ramping.
  • After the hour, the ISO calculates each unit’s actual output compared to the output scheduled in day-ahead. The real-time LMP is applied to any deviation from scheduled, and each unit is paid or charged (depending on whether the unit generated more or less than scheduled) based on the LMP at that unit’s location.
  • Similarly the ISO compares each LSE’s schedule at specific grid locations to the LSE’s actual usage. Again, the deviation from day-ahead schedule is either charged or paid depending on whether the LSE used more or less than scheduled.

Real-time operations

Want to learn more about ISOs and how they operate? ISO Market Basics, an online course by Enerdynamics, gives a thorough overview of how ISO markets work, how services (capacity, energy, operating reserves, and financial transmission rights) are bought and sold in an ISO, the role of ISOs and various market participants, and the various types of electric markets available to market participants.

What is the Least-cost Source of Electricity in Your Community?

by Bob Shively, Enerdynamics President and Lead Instructor

Average Costs Across the U.S.

In our June 2016 blog post titled Economics, Not Policy Mandates, Drive the Growth of Renewables we described how the price of utility-scale wind and solar projects was becoming competitive with traditional forms of generation. The discussion was centered on data developed in 2015. Costs for renewables are decreasing so rapidly that an update using more recent numbers shows even more dramatic results. Stunningly, wind and utility-scale solar PV are now the two lowest-cost generation sources.

Costs in Your Community

The University of Texas at Austin recently performed a related study titled New U.S. Power Costs: by County, with Environmental Externalities that takes into account generation costs similar to those shown above, but it also considered additional externalities. The complete list of factors considered include:

  • Power plant costs including operating plus capital costs
  • Fuel costs
  • Environmental and health costs including air quality and greenhouse gases
  • Infrastructure costs including transmission and distribution, rail, and gas pipelines
  • Integration costs for renewables and distributed energy resources
  • Opportunities for energy efficiency
  • Government financial support for electricity

The University of Texas study analyzed the lowest-cost form of generation by county across the U.S.:

Here we see the dominance of wind in the Midwest, solar in sunny regions of the West, and natural gas combined-cycle turbines in much of the rest of the country. Interestingly, in a smaller number of counties nuclear power is the low-cost resource.

How Costs Affect U.S. Generation Mix

Not surprisingly, planned generation additions and retirements are reflective of cost data.

Given that generation decisions are made at the local and state levels, it seems logical to conclude that regardless of federal policies the movement to gas and renewable generation will continue.

Corporate Purchasers Are As Important as Utilities in Renewables Growth

by Bob Shively, Enerdynamics President and Lead Facilitator 

In recent years, new wind and solar electric generating capacity has outpaced all other sources of power. In 2016, the two renewables sources grew by more than 20,000 MW compared to the next largest source, natural gas, which grew by about 7,000 MW.

net changes in U.S. Summer Gen Capacity.jpg

Source:  Based on data from the EIA website

Much of this capacity has been built under power purchase agreements (PPAs) with utilities either because the utility needs the power to fulfill a state-mandated renewable portfolio standard or, increasingly, because renewable power has become the low-cost supply choice when the utility performs its periodic Integrated Resource Planning (IRP) process. But another key factor leading to the growth of renewables is growth of corporate end-use buyers who sign PPAs with renewable developers.

Indeed some analysts have suggested that corporate buyers have become as important as utilities. The Business Renewables Center tracks publicly announced corporate renewable deals and is showing  4,810 MW of new corporate-funded renewable capacity over the last two years.

Buyers include many well-known companies including Amazon, Apple, Dow Chemical, Google, Microsoft, and Walmart. Google announced that in 2017 they expect to buy enough renewable energy to account for 100% of their usage[1], (which is about equivalent to the energy usage by the city of San Francisco!).

Why Do Corporate Buyers Sign PPAs to Buy Renewables?

Corporate buyers are signing renewable deals for two key reasons. One is that a growing number of corporations have adopted corporate sustainability goals and/or believe that buying clean power enhances their marketplace image. But in many cases, corporate buyers are committing their dollars because they believe it is the best way to lock in reasonably priced power supply over the long-term.

As quoted in a recent Utility Dive article[2], Google’s director of energy and sustainability said: “We are not doing this because it will make us feel good.  These are economic decisions that are also good for the world.”

I’ve heard similar sentiment from the corporate energy buyer for Walmart who said when he goes to the Walmart board for approval for his plans, he doesn’t even mention sustainability; he simply sells renewables deals based on what is the most economic source of energy supply for Walmart. The key is that by signing fixed-price long-term PPAs, corporations are reducing their risk of future electricity price increases.

How Does a Corporate PPA Work?

In competitive retail markets where end users are allowed to buy directly from generators, it is easy to see how a company like Google can lock in fixed power prices through a PPA since the power they buy can be directly used by their end-use facilities[3].

To make things work in a market where the utility is responsible for supplying power to end-use consumers is a bit more complex as demonstrated by the above graphic.

  1. Google buys energy bundled with renewable energy credits (RECs) from a renewable project in a long-term fixed price PPA. The PPA gives Google the rights to all MWh generated plus all RECs associated with the MWh.
  2. As energy is generated, Google resells the MWh into the wholesale market place. The revenue that Google receives varies depending on the market price of electricity. In some cases it will be higher than what Google paid to the renewable developer; in others is will be lower.
  3. Google buys energy supply for its data center from the local utility and pays the regulated utility supply rate. While the cost of the utility supply rate may not exactly match up with the revenues Google receives from selling power in the wholesale market in Step 2, there should be a decent correlation between the two prices since the utility also buys power from the market.
  4. Google applies the RECs to its consumption to verify that its use of electric supply is backed by renewable generation.

While the renewable PPA isn’t a perfect price hedge relative to the cost of utility supply, it is expected to be a reasonable hedge against utility rate movements. And Google gets one other significant benefit — the output from the renewable project does not have to match up in time with consumption by the data center since the utility grid is being used to “store” power when generation and usage doesn’t match.

What is the Future of Corporate Renewables Purchases?  

The Rocky Mountain Institute estimates that over 60,000 MW of new renewables will be needed by 2025 to meet corporate clean power goals. Sixty-five key companies have created a set of Corporate Buyer’s Principles that are intended to guide utilities and regulators in setting rules that allow for ease in signing long-term PPAs.  Signatories include most of the companies already mentioned here plus other well-known companies including Target, Gap, GM, Kellogg’s, Hilton, Starbucks, and McDonald’s. By all indications, corporate support for renewable projects will continue to grow even if U.S. government policy does not support renewables.

Will Low Natural Gas Prices Continue?

by Bob Shively, Enerdynamics President and Lead Facilitator 

In 2016, annual average natural gas prices in the U.S. were the lowest since 1999.

Interestingly, this occurred even with a slight drop in production and slight increases in both demand and exports.

US dry gas production and demand.png

While prices rose a good bit in December due to cool weather, warmer temperatures have pushed prices right back down in recent weeks:


Source: EIA website

Low natural gas prices have had significant impacts on the energy marketplace:

  • For the first time ever, electricity generation by natural gas power plants in 2016 was the largest source of generation in the U.S. surpassing coal which has been the leader since the mid-1900s.
  • The cost of power generation by gas has fallen to unprecedented low levels. Combined with growing low-cost renewable and solar power in some markets, numerous coal units and even some nuclear units have closed or been scheduled for closure.
  • Many independent power products (IPPs) are now questioning whether they can attain enough market revenues to stay in business
  • Exports of LNG are now economic as cargos priced at an index to Henry Hub are competitive in world markets.
  • Industrial gas demand in the U.S. is at the highest level since the year 2000.
  • And both natural gas and electricity consumers have benefited by low utility bills.

Given these factors can we expect that gas prices will continue to stay low, or will prices creep back up? A quick Google search of the phrase ‘2017 gas price forecast’ leads to sites with titles like “Outlook ’17: U.S. natural gas prices could soar” and “Will natural gas go on another run in 2017?”

Natural gas prices are set by the market based on the forces of supply and demand, plus market expectations for the future. So what are the expectations?

  • Demand plus exports is forecast to be flat: According to the EIA February 2017 Short-term Energy Outlook, the level of demand plus exports in 2017 is expected to grow about 1% compared to 2016.


It should be noted that this assumes that electric power generation will fall a bit, primarily because the EIA has forecast a significant gas price increase to $3.54, which makes gas generation less competitive with coal.

  • Supply is forecast to increase slightly: According to the EIA Short-term Energy Outlook, supply is forecast to increase by about 2% due to increasing U.S. gas production.

US Gas Supply.png

And indeed, we have seen natural gas rigs actively drilling for gas increase by 50% compared to this time last year, which would indicate that more supply is on the way.  Meanwhile, natural gas in storage is about 4% above the 5-year average.

  • The natural gas futures market is less optimistic on price than the EIA.

    NYMEX HH 2017 Futures Prices.png

The natural gas futures market, which indicates the current price available today to lock in a purchase or sale of supply in future months, suggests an average 2017 price of $3.03.  This is more in line with forecasts from the IMF and the World Bank, which forecasts U.S. gas prices of $3.00/MMBtu for 2017.

  • Weather doesn’t look promising to help gas prices in the near term: According to weather forecast maps from NOAA, winter may already be close to over with forecasts for both the next month and the next three months showing temperatures higher than normal for most of the country.



So what can we expect for gas prices in 2017?

With production still strong, heating demand looking low for the rest of this winter, and gas in storage above the five-year average, it doesn’t look optimistic for significant gas price spikes. Much will depend on power plant demand for natural gas, and producers are hoping for a hot summer. Absent that, we would expect gas prices to remain at historic lows. Others disagree and think there is potential for a price run-up. That is the fun of the gas markets — no one knows what will happen until it does!
