Austin, Texas-based Industrial Solar was formed in 2021 to install grid-scale solar projects that alleviate high demand charges levied on industrial companies across Texas using a net-metered industrial solar system.

Grid demand charges typically represent 30% to 70% of a commercial and industrial operation’s electric bill. Prolonged hot summer months in Texas from June through September create a lot of demand on the Electric Reliability Council of Texas (ERCOT) grid, pushing prices higher. On-site solar represents an opportunity for savings from these high demand charges, and Industrial Solar seeks to meet that opportunity.
“Our utility-scale solar projects help our ERCOT customers save millions of dollars at the facility level without any capital expense required,” said Wade Gungoll, chief executive officer of Industrial Sun.
Industrial Solar’s net-metered solar solutions involve deploying grid-scale solar projects near industrial facilities. The industrial firm will sign a power purchase agreement rather than owning the project outright, avoiding additional capex costs. As behind-the-meter projects, the net-metered industrial solar projects can significantly reduce the 4CP demand charges across Texas industrial operations.
For years C&I businesses across Texas have been charged a monthly coincidental peak fee, called a 4CP charge, based on how much electricity the business consumed during a previous year peak period when demand on the grid was highest. 4CP stands for the average Coincident Peak demand reading set by a C&I facility’s electric load in each four month seasonal interval.
According to a nascent C&I solar developer, a new solution that goes a step further than on-site solar provides net-metered industrial solar from utility-scale projects that can virtually eliminate 4CP demand charges altogether.
EIG Partners announced a $90 million investment in Modern Energy business Industrial Sun, an industrial solar developer working across Texas. Following a mid-2020 debt financing in Modern Energy, the new investment brings the total investment in the company and its affiliate to $190 million.
“Industrial Sun was a brand new company 15 months ago and now it is capitalized to execute on gigawatts of pipeline opportunities that will further the energy transition,” said Chris Hamilton, chief investment officer at Modern Energy.
Founded in 2021, Industrial Sun’s team has deployed more than 6 GW of cumulative solar projects to date, with Gungoll and Rich Clark, vice president of development, previously working at Savion, 7X Energy (Lightsource bp), SunPower, AP Solar and NRG Energy.
4CP Demand Charges
According to an Industrial Solar white paper blog series, 4CP demand charges can be broken down into three steps for a basic evaluation:
In one 4CP example, a Centerpoint Energy customer paid $56.51 per 4CP kilowatt, which equals $56,510 per MWh during the 4CP time samples. For a 50 MW industrial load application, that becomes $2.83 million in power usage for a single hour of an industrial application, according to the company.
No state has more solar capacity on the way than Texas in the coming years. The Energy Information Administration (EIA) projects as much as 36 GW of solar capacity will be added in the next five years, adding on to the 16 GW installed thus far and leapfrogging the Lone Star State over California in terms of installed capacity.
To date, Texas has enough solar capacity to power the equivalent of nearly 2 million homes. Over 10,000 Texans are employed by the solar industry, and the Solar Energy Industries Association (SEIA) reports that over $19 billion has been invested in the technology there through Q3 2022.
