The Price of Regulation for Energy Storage

The Price of Regulation for Energy Storage

Ancillary Services and Energy Storage Markets

Ancillary services – Frequency Regulation, in particular – has been critical to achieving desired hurdle rates among front-of-the-meter storage projects in deregulated markets. However, given finite size and price sensitivities in these markets, what will be the impacts for developers?  We have extensive thoughts on the topic here at Enovation Partners, and, suffice to say, “the devil is in the details” when considering the answer. 

The structure and rules of many ancillary service markets are complex, leading to unforeseen outcomes and disruptions when a new technology bursts on to the scene. If ancillary services products are configured with storage in mind (e.g. discharge duration, compensation for speed), there is a great fit with current storage capabilities.

However, markets are small:

Hinderances to storage adoption

Further obstacles to storage adoption come from each market’s complex pricing mechanism. In many cases, there is no simple price-setting mechanism in terms of supply/demand, and in other cases there is very little competition or price transparency.


PJM’s frequency regulation rules from 2012 encouraged a boom in storage, during which time owners and operators of storage benefitted from favorable market rules and compensation mechanisms (e.g. pay-for-performance).  Commitment to net neutral signals for storage and limits on sustained signal durations leading to batteries acting out of harmony with system needs, and – at least from the Market Monitor’s perspective – overcompensation for Frequency Regulation resources following the Reg D signal.

In 2017, PJM changed its rules around neutral signals, signal intensity, and settlement mechanisms in a manner that left storage owners with significantly less revenue and, for some, substantially accelerated battery degradation. These rule changes were struck down after in an April 2018 ruling leading to a correction in pricing and signal.  FERC has requested a technical conference for late 2018, and thus the wheel of time continues for PJM Reg D.

In New York, a potential state mandate of 1.5 GW of storage would create a market disconnect by injecting new, potentially uneconomic supply to meet a largely unchanging demand.

Frequency regulation market price declines by 90% following the installation of a 100 MW Tesla battery in South Australia - frequency regulation products were previously priced by units with highly volatile variable prices



We expect markets to struggle when there are swift changes to underlying technologies in a Regulation supply stack. Storage’s innate ability to provide ancillaries faster and cheaper than current price setting units will drive a step change in clearing prices as storage usurps gas-fired generation as the marginal unit. 

At Enovation, we expect price drops to reflect the delta in the units’ marginal prices to provide ancillaries.  As a result, market sensitivity to dramatic price changes in the near-future as storage projects could have dramatic implications for future development decisions by Independent Power Producers and investors. Prudent developers should have a clear idea of how additional market entry can impact pricing, and hedge by configuring systems to earn other revenue streams.

What does this mean for the economics of storage projects? How will overall storage penetration be affected? Are mandates achievable? Enovation Partners’ expertise and analytics capabilities guides our clients through issues like this everyday

Fuel an Industrial Resergence

PGW Can Help Fuel an Industrial Resurgence in the Philadelphia Region

Philadelphia. November 13—At today’s meeting of the City Council of Philadelphia, Enovation Partners’ directors William Kemp and Todd Allmendinger testified about how to use the assets of Philadelphia Gas Works (PGW) to help drive economic development through public-private partnerships.

The Philadelphia region possesses potent competitive advantages, flowing from its proximity to the massive energy production of the Marcellus and Utica shales, its status as a major transportation hub both domestically and internationally (port, rail, trucking), its world-class educational institutions and workforce capabilities, and its long history of leadership in chemicals, pharmaceuticals, and other energy-related industries. Public-private partnerships could strengthen PGW’s capability for contributing more broadly and flexibly to Philadelphia’s future as a key player in America’s industrial renaissance.

Kemp and Allmendinger also provided examples of how other metro regions, such as Jacksonville, FL, and Brownsville, TX, have used public-private partnerships to move forward on similar gas-related economic development opportunities. Their panel included supporting testimony from Alan Mosley of the Jacksonville Chamber of Commerce and Alicia Farag of the Gas Technology Institute.

PGW is the nation’s largest municipally owned gas utility. The testimony comes as Connecticut-based utility company UIL Holdings Corporation trying to keep alive its offer to purchase PGW, a move supported by Philadelphia Mayor Michael Nutter. City Council President Darrell Clarke recently announced that the council was against the sale and would not hold hearings on it.

Shale Gas, Collaboration, and Regional Growth

The revolution in natural-gas production can provide immense benefits to the U.S. economy, began Allmendinger. With diligent regulation of groundwater and methane-emissions risks, the overall environmental benefits should be substantial, too. Switching to natural gas from fuel oil and coal in power generation and from fuel oil, diesel, and gasoline in transportation and industrial applications, promise attractive economic and environmental paybacks.

The Philadelphia region should be at the forefront of that natural-gas revolution, said Allmendinger. Compared with many other cities around the country, however, the region’s progress on capturing natural-gas-driven benefits is modest. For instance, said Allmendinger, Jacksonville, FL, doesn't enjoy the proximity to gas reserves, infrastructure, industrial base, or educational resources that Philadelphia does. But it is using its municipal utility and harbor as platforms for sustained growth, creating partnerships with businesses, attracting capital and investment, bringing together labor, capital, customers, and businesses, and positioning Jacksonville to become an East Coast market leader in small-scale LNG and compressed natural gas (CNG).

  • Three consortia of energy and financial players are competing to build LNG production and distribution terminals in Jacksonville, aimed specifically at serving the rail, maritime, and heavy-duty trucking industries. The regional market can support at least two such facilities.
  • Local municipalities and UPS are ordering hundreds of natural gas-fueled vehicles.
  • Shipbuilders and maritime operators are building LNG-fueled ships and plan to export LNG to utilities and industrial customers in the Caribbean region, as a superior alternative to diesel or bunker fuel oil.

Together, these projects represent several hundred million dollars in direct investment and hundreds of jobs in engineering, construction, terminal operations, and transportation.

Pennsylvania Growth in Natural Gas and LNG as Fuels

Another support for the Philadelphia region’s economic renaissance, said Allmendinger, is the fact that new sources of low-priced natural gas are displacing diesel fuel for transportation and high-horse-power applications—in trucking, waste management, public transportation, rail, marine, and mining.

Allmendinger pointed to the CNG fueling-station construction effort at Pennsylvania’s public transit agencies, approved by the state’s Public-Private Partnership (P3) Board. The private partner will design, build, finance, operate, and maintain the stations; many Pennsylvania companies want to participate. PGW President and CEO Craig White recently joined Governor Tom Corbett in opening Philadelphia’s first public CNG fast-fill pumps.

While the export of LNG from the Port of Philadelphia may face challenges, the Port’s activities will require LNG as a fuel, said Allmendinger – for marine vessels, locomotives, industrial, and off-grid power generation projects. This will require storage, distribution, and fueling operations. Several Pennsylvania energy companies are interested in expanding their operations into these areas.

To meet expanding LNG and CNG needs across the nation, natural gas utility companies are accelerating large-scale replacement programs to upgrade infrastructure while at the same time implementing technologies and practices to create operational efficiencies, according to related testimony by Alicia Faraq, senior manager for the data and integrity management research program at the Gas Technology Institute. PGW has supported the development of next-generation technologies and business practices that create operational efficiencies while maintaining public safety and ensuring long-term system integrity, said Faraq.

The market response to the growing advantages of LNG and CNG is accelerating, said Allmendinger. PGW could leverage its physical assets and human resource capabilities to gain a significant and profitable share of this market. “To move as quickly as needed and field the required marketing expertise, PGW would be well advised to seek suitable partners in a P3 structure,” said Allmendinger.

In response to questions by council members about how to structure public-private partnerships, Kemp testified that PGW should bring to the negotiating table its capabilities and objectives and work out with its private partners the ownership and operating structure that would succeed best in the marketplace. The structure would be fitted to the opportunity. Agile public and private companies make these types of strategic partnering decisions as a normal course of business.

"Southeastern Pennsylvania should seize this historic opportunity to capitalize on its unique geographic, logistical, human, and manufacturing endowments, and use public-private partnerships to take full advantage of the natural gas revolution in its backyard.”
