Comments of CFACT regarding Dominion Energy\u2019s 2023 IRP and their need for additional gas fired generating capacity during the 15 year planning period<\/p>\n\n\n\n

Introduction<\/strong><\/p>\n\n\n\n

In their latest IRP, Dominion Energy argues that they will need to add some gas-fired generating capacity during their 15-year planning period. We support this expansion. Several lengthy comments have been filed in opposition to their proposal. We believe they are misguided.<\/p>\n\n\n\n

In actuality, Dominion must not just add what they propose, but considerably more gas-fired capacity to their operations. This is because the amount of battery storage the company will need to reliably make their proposed renewable energy expansion possible is far greater than what they currently have planned.<\/p>\n\n\n\n

The economics are clear. The required storage is prohibitively expensive. Thus, gas-fired backup is a better alternative as it is by far less costly. Moreover, given the much higher capacity factor and low cost of gas-fired capacity it would be more cost effective to use fewer renewables. This is especially true of the offshore wind capacity which is a serious threat to whales and other marine life. Offshore wind should not be built.<\/p>\n\n\n\n

These issues are discussed briefly below. Additional analysis by Dominion is called for to properly address them.<\/p>\n\n\n\n

Grossly inadequate storage<\/strong><\/p>\n\n\n\n

Dominion\u2019s preferred option, Option B, calls for 2,370 MW of battery storage in the planning period. MW are the battery discharge rate, not the storage capacity. Assuming these are standard 4-hour batteries, the storage capacity is 9,480 Mwh.<\/p>\n\n\n\n

This is an extremely small amount of storage, nowhere near enough to back up the proposed increase in renewables. A simple analysis makes this clear. Figure 1.1.1 projects an increase in DOM Zone summer peak of over 10,000 MW.<\/p>\n\n\n\n

It is likely that Dominion will see load increases of 5,000 or more, possibly often. This load is supposed to be met using renewables and batteries. This isn\u2019t likely to happen. Consider the simple case of a 12-hour night with low wind fulfilling that load. The storage requirement is 60,000 MWh, which is over six time the proposed storage capacity. Even if the batteries had a 10-hour capacity they would not come close to meeting the need.<\/p>\n\n\n\n

Even worse, this simple case is far from being the worst that is likely to occur. Multiple cloudy hot and cold days with low wind are common in Virginia. Detailed historical analysis will be needed to properly estimate the likely maximum required storage capacity, and it will certainly be in the hundreds of thousands of Mwh.<\/p>\n\n\n\n

Even assuming huge battery price reductions, this much storage would be prohibitively expensive. Gas-fired backup power is a better option.<\/p>\n\n\n\n

Dominion has indicated it plans to meet some of this need with imported energy. But all the neighboring utilities are pursuing a similar dependence on renewables. The spatial extent of protracted low wind cloudiness with high load is often very large, including all the states near Virginia. Therefore, it is very likely that energy will not be available to import during these episodes. In fact, Dominion made this very point in its 2022 IRP Update. A much better path than relying on out-of-state electricity will be for the company to expand its gas-firedgenerating capacity.<\/p>\n\n\n\n


Low projections of load growth<\/strong><\/p>\n\n\n\n

Dominion says the large projected load growth used in the IRP is mostly due to new data centers, not electrification of other energy uses. However, the load growth from electrification will also be very large under present policies. A great deal of gas-fired generation will be required to meet this additional load.<\/p>\n\n\n\n

The reality is complex, but if we will keep it simple enough one can readily see the stark general picture.<\/p>\n\n\n\n

To begin with, just consider electrification of gasoline usage, most of which is for cars and light trucks. According to EIA, Virginia\u2019s estimated 2021 gasoline consumption is around 440 trillion Btu. The conversion is 3,412,000 btu = 1 MWh. So that is about 130 million MWh in gasoline energy. Also in 2021 Virginia\u2019s electric power generation is 93.5 million MWh. Thus, the gasoline energy is 1.4 times the total power generation. If it takes this much energyto power cars and light trucks in the Old Dominion, then it becomes necessary to build new generation capacity that is almost one and a half times the Commonwealth\u2019s present generation to make the transition. We have seen no plan that even begins to seriously address
this issue.<\/p>\n\n\n\n

Of course, a real analysis, which Dominion should do, would get very technical. For example, car engines are only around 40% efficient. So one might argue that only 40% of that 130 million MWh, or 52 million, is needed to run the electric version. That is still well over half of present generation. But the electric power and electric car system is also far from 100% efficient. There are line losses, storage losses, motor losses, etc. But the bottom line holds true: if 52 million MWh has to be used, then a lot more has to be generated. And this is just with respect to gasoline. The present policy goal is to electrify as much fossil
fuel use as possible. Natural gas use is huge. EIA says Virginia\u2019s 2021 consumption was about 700 trillion Btu, or almost twice as much as gasoline, and many gas uses are efficient. Distillate oil, including diesel and heating oil, is roughly another 200 trillion Btu. Even coal is around 70 trillion Btu.<\/p>\n\n\n\n

It seems likely, therefore, that widespread electrification could easily double the load increase from that projected for the planning period in the IRP. A great deal of new gas-fired generation will be needed to meet that load. Dominion needs to include this case in its IRP.<\/p>\n\n\n\n

Offshore wind is expensive, redundant and environmentally destructive<\/strong><\/p>\n\n\n\n

Instead of building new gas-fired generating capacity to backup renewables, it will be far more cost effective to use gas as a primary energy source. Having gas capacity sit idle simply because the wind is blowing or the sun shining for part of the day is redundant and expensive. Dominion should analyze this issue.<\/p>\n\n\n\n

The case of offshore wind is particularly extreme. In all five options, Dominion projects 3040 MW of new wind, mostly offshore, on top of the 2,600 or so MW already in process. The total cost is presently projected to exceed $8 billion per 1,000 MW or over $45 billion. This for atechnology that seldom produces full-power and sometimes produces none at all, including
during periods of peak load.<\/p>\n\n\n\n

Moreover, the projected cost of offshore wind projects has increased dramatically in recent months, on the order of 50% at this point. It is likely that the IRP needs to be redone to take such huge increases into account.<\/p>\n\n\n\n

In addition to this exorbitant cost, offshore wind has been implicated in numerous whale deaths \u2014 including the extremely endangered North Atlantic Right Whale. Strangely, the IRP does not include this issue.<\/p>\n\n\n\n

IRP Appendix 5L is a five-page list of the many Environmental Regulations that Dominion is scrutinized under. On page 194, in a section called \u201cWildlife\u201d, there are just 3 entries. These entries are all about the endangered Atlantic Sturgeon, which is threatened by hot water from nuclear power plants. There is no mention of the Marine Mammals Protection Act harassment
authorizations, even though the present offshore wind construction and operation is waiting for one and they cannot start the offshore portion of the project without it. Also not mentioned are the crucial Environmental Impact Statement and BOEM approval of the project.<\/p>\n\n\n\n

This is preposterous, as the threat to whales is clear. The project creates what amounts to an intense noise wall that forces the whales to go around, either to the East or to the West.<\/p>\n\n\n\n

Immediately to the East lies the westernmost lane of the very busy coastal ship traffic. To the West lies the equally busy coastal barge traffic. Both are deadly to the species.<\/p>\n\n\n\n

It seems the project was deliberately located where there is the least shipping traffic. This would make sense if it were not for the whales and other marine mammals. As it is the projectcloses the low shipping corridor, which the whales undoubtedly use. Being hit by ships is the leading cause of death to whales, and the placement of wind turbines in these waters will
facilitate more such collisions.<\/p>\n\n\n\n

In summary<\/strong><\/p>\n\n\n\n

CFACT supports Dominion\u2019s construction of new gas-fired power plants. The company will need a great deal of new gas-fired generating capacity in order to meet its vastly increasedbase load that is projected over the planning period. Many of the factors and drivers involved are not included in the present IRP, and Dominion needs to properly address them. In the  meantime, however, given all these factors, it would seem building more gas-fired capacity is both a proper and responsible course to set.<\/p>\n","protected":false},"excerpt":{"rendered":"
