Electricity is instant.
The work behind it isn't.
Every time someone flips a switch, a system of planning, investment, markets, and real-time decisions goes to work. At Guzman, every part of that system answers: how is power best shaped to unleash society’s potential?
The Guzman Way
Our Work Starts with each Customer’s Unique Needs
Customers are unique. Guzman builds every deal specifically tailored to the individual distribution utility’s needs and is a partner across each stage.
01 Customer Preferences
No Two Customers Have the Same Priorities.
Every customer configures their energy contract across at least five dimensions — from who brings the resources to contract length and environmental attributes. Some want maximum budget certainty. Some want more market participation. Others need to match local generation, support clean-energy goals, or plan for decades ahead. Guzman turns those priorities into a power solution with room to evolve.
02 Energy · MWh
Electricity Has to Be Consumed the Moment It’s Made.
Energy is the component of electricity that matters to consumers — light, heat, internet, cooling, compute. It needs to be consumed or stored in real time. Guzman’s 24/7 operations center delivers it through a portfolio of resources and continuous market engagement.
Generation alone is not enough. Every source has tradeoffs and must be balanced for the customer’s needs.
03 Regulatory Ecosystem
Who Governs the Grid?
We operate within and guide customers through the regulatory ecosystem — reserve margins and capacity accreditation regimes, market rules, NERC, FERC and state requirements, ancillary services, balancing authority requirements, and clean energy regimes.
04 Capacity · Peak Power Demand
Planning for the Hottest Hour of the Hottest Day
By regulatory obligation, Guzman must plan for peak demand — the hottest hour of the hottest day (and the coldest hour of the coldest day) — and then add a Planning Reserve Margin (PRM) on top of it. That PRM typically falls between 20% and 40%, depending on the season and market. Together, peak demand plus PRM form the total capacity obligation; for example, on a 100 MW peak, the system must have 120 MW accredited and available.
05 Transmission · Open Access
The Supplier Can Change. The Wires Don’t Move
We access and manage open access transmission for our customers — Network Integration Transmission Service (NITS) for network-wide grid access, point-to-point to connect key markets, and physical delivery or financial congestion management depending on the market.
Every Utility is Unique
The Structure Is Tailored to the Local Utility and the Load.
Supply is assembled across technologies, developers, and geographies — unconstrained by ownership or any single developer relationship.

Guzman Energy Summed Up
Guzman Energy is a wholesale power supplier. Cooperatives and municipal utilities buy electricity from us rather than generating it themselves, and we assemble that supply from a portfolio of wind, solar, gas, hydro and storage rather than from any one plant we happen to own. Alongside the power itself we handle the contracts, the transmission arrangements and the day-to-day market operations that sit behind it, so the distribution utility keeps its own business model and its relationship with its members.
What is a co-op?
A cooperative is a utility owned by the people it serves. Members elect the board, surplus comes back to them as capital credits, and there are no shareholders to pay. Most co-ops serve rural and suburban territory and buy their wholesale power rather than generating it, which is where Guzman comes in.
An investor-owned utility, or IOU, works the other way round. It is owned by shareholders and profits are distributed to them, state regulators set its rates and policy, and it is often vertically integrated, owning its own generation.
What is a municipal utility?
A municipal utility is city- or government-owned, governed by a city council or board. Revenue stays in the community, and territories are typically urban and small-city.
Organized vs. bilateral market?
In an organized market — SPP or MISO — an RTO centrally dispatches generation, runs day-ahead and real-time energy markets, and manages congestion through financial instruments. In a bilateral market — SERC or WECC — there is no central operator: transmission access runs through each utility’s own tariff, and buyers and sellers contract directly with one another.
What is NITS?
Network Integration Transmission Service is a standing agreement giving a load-serving entity network-wide grid access. The agreement belongs to the customer, and its charges are based on the customer’s coincident peak demand — not on which generator happens to be running.
What is ELCC?
Effective Load Carrying Capacity is the factor by which a generator’s nameplate capacity is reduced when counted toward a capacity obligation. Solar might count at 20% of its installed size, gas at 90%. Values differ by regulatory market and season.
What is a planning reserve margin?
Capacity held above forecast peak demand so the system has headroom when conditions are worse than expected. It often falls near 20–40%, varying by season and market, and it is a regulatory obligation rather than a choice.
