Gridcog for property and real estate

Energy modelling for property and real estate portfolios

Property owners, developers and their advisors use Gridcog to model solar, battery storage and EV charging across a portfolio before they invest. Simulate each building's load, tariffs and grid connection, compare scenarios on cost, income and emissions, and build the case for net zero buildings that owners, lenders and tenants can check.

Key points

  • 3.5 MW

    Carb0n's first UK project using Gridcog combined 3.5 MW of solar car ports with a 4 MWh battery at a retail outlet in southern England.

  • EnergyTec

    EnergyTec, Western Australia's largest embedded network service provider, has used Gridcog to model two of the biggest property portfolios in the state.

  • £27m

    Sustain Commercial Solar, which models its behind-the-meter revenue stack in Gridcog, estimates around £27m of investment secured over 12 months (case study, October 2026).

Why are property owners investing in on-site energy?

Property is becoming a utility.

Buildings now supply energy, heating, cooling and EV charging to the people who use them. On-site solar and batteries can turn that energy from a cost into income, and help owners meet net zero targets. Meanwhile, electrifying heating and transport keeps raising the load a building has to serve.

How can property portfolios model solar, storage and EV charging for net zero?

Gridcog optimises the selection, sizing and controls of clean energy assets in new and existing properties.

Start with each site's load profile, tariffs and grid connection. Then test what solar, storage, EV charging and flexible load add, alone or together, across a whole portfolio.

  • New developmentsSize solar, batteries and EV charging into the design, including private networks

  • Existing buildingsTest retrofits against today's load, tariffs and grid connection limit

  • PortfoliosDuplicate a set-up for similar building types and compare sites side by side

  • Market accessValue a battery's earnings in wholesale, ancillary and capacity markets alongside bill savings

How do landlords and tenants share the value of on-site energy?

Model each party separately.

Gridcog lets owners, developers, managers, tenants and buyers sit in the same project as separate participants, so everyone sees the costs and benefits of the energy assets from their own side.

Who controls supply matters. At Carb0n's retail outlet project the landlord controlled the energy supply, and Peter Massie, Head of UK at Carb0n, says that centralised control ‘allowed us to create value for the landlord that would not have been possible if individual tenants managed their own supply.’ Inside embedded networks, EnergyTec compares several tariff configurations in one project to see the effect of different network charges.

What do solar and batteries do for a building with peaky demand?

They cut the most expensive imports, if the battery is there for the peak.

Gridcog Energy Analyst Joshua Elliott modelled Wembley Stadium using an assumed 4 MW peak and 40 major events a year. Solar alone could not reach evening kick-offs. Adding a 3 MW / 6 MWh battery roughly halved imports on event days. On the other days, the battery traded in wholesale, ancillary and capacity markets.

What if a building has no spare grid capacity?

Use flexibility before you wait for an upgrade.

Gridcog Senior Energy Analyst Ashok Willis modelled a London shopping centre whose load grows 1.68% a year, with public EV chargers and no headroom on its connection. Doing nothing left 2.5 MWh of unserved load by 2035. A 2 MW / 2-hour battery, or shifting flexible load, met all demand within the existing connection.

Frequently asked questions

Can't see your question?

Get in touch

Yes. Gridcog models multiple sites, assets and commercial arrangements in one project, so you can compare buildings side by side and test portfolio-wide options. EnergyTec duplicates set-ups for similar building types and has used Gridcog on two of the biggest property portfolios in Western Australia, with two or three people working on a project at a time.

Yes. Gridcog models how energy moves inside a private network and how it interacts with the external grid, and links those flows to financial outcomes. EnergyTec uses it to compare tariff configurations inside an embedded network and to match solar and battery choices to each site's load profile. More on embedded networks and private wire.

Often, yes. A battery can shift imports away from expensive peak periods and lower network demand charges, and with market access it can also earn in wholesale, ancillary and capacity markets. In operational real estate, Carb0n times batteries to peak grid demand and captures savings without on-site generation.

Gridcog models emissions alongside costs, so you can see what each scenario does to a building's carbon as well as its bills. It supports standard Scope 1 and Scope 2 reporting and 24/7 carbon-free energy (CFE) targets, and it can optimise for emissions reduction as well as commercial outcomes.

Gridcog models existing and planned connections, dynamic connection limits and future load growth, then shows where load would go unserved. You can compare the cost of a grid upgrade with solar, battery storage or shifting flexible load, as in our London shopping centre example, where a 2 MW battery met growing demand within the existing connection.

Yes. Gridcog reports set out system limits, financial outcomes and the effect of design changes, and every input and assumption stays visible. EnergyTec's clients have used Gridcog reports to take projects to financiers and other stakeholders, and Carb0n uses them to explain the finances to clients who aren't energy experts.
