LS Power buys back six gas plants from NRG for $4 billion

$4 billion is the cash price LS Power and NRG set for six gas-fired plants with 4.9 GW of capacity.

The companies said in yesterday’s joint announcement that the deal returns six units to LS Power a little over nine months after NRG closed its larger purchase from the same seller.

NRG had agreed in May 2025 to buy 18 LS Power gas plants with 13 GW of capacity for about $12 billion, including five in Pennsylvania. That acquisition received final approval and closed on Jan. 30. NRG’s chief executive said NRG was “not even trying to sell.” The joint account added: “LS Power called with an unsolicited offer.”

How much of the original deal has reversed?

• Six of 18 units: One-third of the original plant count is returning to LS Power in the reverse trade.
• 4.9 GW of 13 GW: Nearly 38% of the original capacity is involved, a higher capacity share than the unit count.
• $4 billion of $12 billion: The cash consideration equals one-third of the original, roughly $12 billion purchase price.
• Four states: New York, Rhode Island, Connecticut and Texas host the six assets. Three are Northeast plants and three are in Texas. None belongs to the five Pennsylvania plants in the original package.

The six assets average about 817 MW each, compared with roughly 722 MW across the original 18-plant package. On a simple cash-per-kW basis, the reverse sale equals about $816, compared with $923 for the May transaction, a roughly 12% arithmetic gap.

That comparison does not establish a valuation discount because the assets differ in geography and mix, and no plant-level capacity factors, fuel contracts, condition data, revenue figures or operating margin were provided.

On disclosed figures, NRG would retain 12 of the 18 acquired plants and 8.1 GW of the original capacity if the sale closes. LS Power would recover six units and 4.9 GW, though the announcement does not break capacity among the plants.

Takeaway: Six assets have changed hands twice, but the second transfer covers one-third of the original plant count.

Why do Queens and Burrillville matter?

Queens and Burrillville sit within the three-unit Northeast portion of the sale. The assets are in New York, Rhode Island and Connecticut. MDN’s explanation is that the three plants run on gas that comes mostly from the Marcellus and Utica.

That connection makes plant ownership relevant to upstream gas demand, rather than a neat regional power story.

Ownership does not dictate consumption. Dispatch and utilization determine how much gas the units burn, while fuel contracts and hedging determine the economics; none of those operating terms were disclosed.

LS Power would regain the Northeast assets, and NRG would shed them, but a title transfer alone would not change their dispatch profile. No Marcellus or Utica volume, pipeline path, supply-contract percentage or plant-level capacity was given. Any precise upstream volume claim would be arithmetic without operands.

Takeaway: The Northeast assets matter because their fuel draw is mostly linked to Marcellus and Utica gas, not because ownership alone changes demand.

What must happen before the boomerang lands?

The announced terms are clear on headline consideration: $4 billion in cash for 4.9 GW across six plants. The announcement identifies no expected closing date, regulatory timetable, financing plan, plant names, state capacity split or operating metrics.

Those omissions leave the economics unresolved. Dispatch, heat rate, fuel cost, capacity factor and power prices would shape the margin, but no figures allow the six assets to be ranked against the wider 18-plant package.

The prior acquisition received final approval before closing. The reverse sale carries no disclosed closing date or approval calendar, so a completed operational shift should not yet be treated as fact.

For NRG, completion would convert six recently acquired units back into cash. For LS Power, it would restore 4.9 GW of gas-fired generation.

Watch the closing timetable first, then disclosed operating economics. Until they arrive, about $816 per kW remains arithmetic, not a valuation verdict.

Takeaway: The $4 billion price is announced, but the closing date and operating margin remain undisclosed.
