Customized Energy Solutions makes the complicated part of electricity pay

An electricity bill looks reassuringly ordinary. A date. A quantity. A total. In a retail-energy case study published by Customized Energy Solutions, however, a single complex industrial invoice can involve more than 200,000 calculation inputs. Imagine a restaurant receipt that needs a small accounting department to explain the bread. The apparent simplicity is the achievement.

A bill with 200,000 moving parts

CES’s anonymous customer serves industrial loads and data centers. Its contracts carry individually negotiated pricing, interval consumption, grid-service charges, and later adjustments to wholesale settlements. CES says BLUE, its retail platform, generates more than 60 million ancillary-service rates each month for this engagement. A “rate” here is a component of the calculation, not another person receiving a bill.

The company’s claim is that these arrangements run through configuration rather than repeated custom development. New billing requirements become settings and workflows. That matters because every negotiated variation otherwise risks becoming a software project, while the electricity keeps flowing and the money keeps moving.

There is a whole business hiding inside this unlovely detail. CES handles the places where physical electricity becomes a forecast, a bid, an instruction, a certificate, and finally a sum somebody must pay. The energy transition has plenty of photographs of turbines. Its invoices are less photogenic, and rather harder to get right.

The paper route that never happened

Stephen Fernands encountered the opportunity while working at PECO as electricity markets opened to competition. His assignment involved helping independent power producers understand the new retail landscape. In a 2021 interview, he described the thought that followed: “I realized, OK, maybe I should try being more entrepreneurial here.” He left to advise participants independently.

A company feature supplies a smaller, more revealing scene. Early on, with the living room serving as an office and the first client still elusive, Fernands considered taking a paper route. His wife, Rochelle, argued that the extra work would drain the effort needed to build CES. Her counsel was wonderfully economical: “Stay the course.”

“Stay the course.”

Rochelle Fernands, recalling the early client search

Founded in 1998, the firm grew from advice into execution. By its 2023 anniversary, CES reported supporting more than 900,000 active retail accounts and processing over three million electronic data interchange transactions a month. These were customers’ accounts passing through its operations. The distinction explains the business: CES can matter to a very large number of electricity users without being the name they see on the bill.

The color chart of competitive power

The products have names a decorator could love. BLUE supports retailers. GOLD supports wholesale operations. RED tracks renewable certificates. GridBOOST handles optimization and bidding. CoMETS models project economics. Market IQ follows the rules and proceedings that influence all the others. The palette organizes a decidedly technical collection of jobs.

For a competitive electricity or gas retailer, BLUE manages enrollment, usage data, billing, and the electronic exchanges with utilities. Error queues help staff find transactions that need attention. APIs connect the platform to other systems. The practical benefit is a back office that can handle the product after a salesperson has persuaded somebody to buy it.

GOLD addresses generators and asset owners. Its work includes round-the-clock market operations, scheduling, telemetry, dispatch, outage coordination, and settlement verification. Telemetry connects the physical resource to the operating desk; settlement checks connect its activity to the money. RED handles a different obligation: tracking renewable energy certificates and the requirements attached to renewable portfolios.

CES occupies an intersection of consulting, enterprise software, and outsourced energy operations. It sells to independent power producers, utilities, cooperatives, community choice aggregators, developers, investors, and large energy users. Its commercial model combines hosted platforms with managed services and consulting engagements. The buyer is paying for a function as well as a tool.

That combination is the useful distinction to test against alternatives. ACES also offers outsourced energy management. VertexOne offers retail billing and EDI software. A buyer might also assemble specialist consultants and optimizers. CES’s proposition is to put several connected disciplines under one roof. Whether that improves a particular portfolio depends on the work the customer actually needs.

One battery, several ways to earn

Consider the Kearsarge project announced in May 2022: 4.4 megawatts of solar generation and 10 megawatt-hours of storage in Bellingham, Massachusetts. CES brought GridBOOST to scheduling and bidding, taking account of asset constraints, price and weather forecasts, New England market rules, and state incentive programs.

The announcement projected a 20–50% revenue increase. That range was an expectation for this site, not a universal return or an audited result. The interesting part is the mechanism: the battery could earn through more than selling electricity, including participation in capacity and frequency-regulation markets and Massachusetts programs.

GridBOOST’s product description puts these competing opportunities into one optimization problem. Charging now affects what the asset can do later. A contractual restriction can change the preferred bid. Availability, operating limits, and incentives have to enter the calculation together. A battery earns according to the decisions surrounding it.

California offers another concrete example. Under a multi-year agreement announced in December 2023, CES was to become Peninsula Clean Energy’s scheduling coordinator from January 15, 2024. The responsibilities included forecasting, scheduling load and generation, resource optimization, and congestion revenue rights. Sonoma Clean Power announced a storage-optimization partnership the following month. These engagements show where CES fits: behind public power portfolios that require daily commercial operation.

The forecast must survive the invoice

CoMETS brings the discussion forward to the investment decision. Its modeling covers dispatch, several revenue streams, technology configurations, degradation, and financial results. The newer self-service offering advertises long-term price forecasts and nodal analysis for PJM, ERCOT, and CAISO. Developers and lenders can examine how location and assumptions change an energy project’s economics before committing capital.

The discipline is useful beyond batteries: specify the constraints before admiring the return. Test different prices, cycling patterns, contract terms, and market rules. Then check that the proposed operation can be measured and reconciled. A forecast describes possibilities; it does not relieve an asset owner of execution.

CES’s September 2026 billing commentary makes a related distinction. The distribution-company incident it discusses began with a data and back-office failure upstream of the retailer. An elegant invoice cannot correct every defective input or create a market mechanism for recovering every historical error. The company argues for traceable calculations and operational controls. Readers can copy the habit of asking where the data came from before debating the total.

Costs belong in that examination too. Consulting, platform integration, telemetry, operating support, and the asset’s own wear all affect the decision. A sensible procurement compares those costs with the value of the work and the expense of providing it internally. On its retail-services page, CES explicitly offers auction revenue rights work on fixed-fee or performance-based terms; that specific option should not be assumed to describe every engagement.

Optimization requires usable market access, accurate inputs, and a resource that can follow the chosen strategy. A facility unable to change its consumption has less flexibility to sell. A forecast built for the wrong market can be beautifully precise about the wrong opportunity. Good software makes these constraints visible; the economics still have to work.

Electricity that earns a living

The company also has an unusually explicit purpose. Its mission links open energy markets with economic development and includes a commitment to honoring God and clients. Its careers materials emphasize ethics, humility, mutual respect, and collaboration across countries. Those are stated values; the more tangible expression is CES CARES.

CES CARES works on productive uses of clean energy and rural enterprise. Its portfolio includes silk livelihoods in Meghalaya, experience centers in Nagaland, and technology roadshows in Zambia. The approach combines equipment with skills, finance, partners, and routes to customers. Electricity becomes more consequential when somebody can use it to process a crop or sustain a business.

Back in the software business, CES has added AVA, an assistant inside BLUE that answers platform questions, while retaining human support for complex inquiries. It is a modestly practical application: help a user understand a process, then let the operating system carry it out. That suits a company whose appeal lies in making difficult work repeatable.

The question running through CES is what happens after the attractive idea. After the new retail contract, after the battery purchase, after the promise of clean power. Someone must translate the idea into instructions, evidence, and payment. CES has made a profession of that translation. The invoice, at last, can look ordinary.
