Storen develops, engineers and operates grid-scale battery storage — turning intermittent renewable generation into firm, dispatchable, revenue-generating capacity across Türkiye, Southeast Europe and Iberia.
Illustrative dispatch profile
In under three years, EPDK has issued pre-licences covering more than 33 GW of storage-integrated generation capacity — roughly 37 GWh of energy. Today, fewer than 500 MWh sit in commercial operation. The distance between an allocation on paper and steel in the ground is the largest execution gap in the region's energy transition. Storen exists to close it.
Allocation is not delivery. Delivery is the whole business.

Actually in commercial operation
Not a metaphor. This is the physical and commercial journey that every megawatt-hour in our portfolio makes, and the reason the asset earns anything at all.
At midday the sun delivers more than the grid can absorb. Prices sag, sometimes below zero. Without storage this energy is curtailed — switched off at the inverter and simply lost.
We develop to the standard a lender's technical adviser will apply, not the standard that gets to financial close fastest. Grid studies, geotechnical work, fire strategy and warranty structure are settled before we ask anyone for capital.
We do not manufacture and we are not tied to a supplier. Cells, PCS and EMS are selected against your dispatch profile, degradation tolerance and warranty appetite — then tendered competitively and held to the specification.
A battery earns from arbitrage, ancillary services and capacity — layered, not chosen. We model the stack at development stage and keep optimising it after commissioning, because that is where the last points of IRR live.
Origination, permitting, engineering, EPC, commissioning and O&M under a single contract line. When something goes wrong at 03:00 on a Sunday, there is no interface to argue about.
A storage plant is not a box of batteries. It is six systems that have to agree with each other, continuously, for twenty years.
Hover a node
Move the controls. Watch the asset decide when to buy and when to sell. This is the arithmetic underneath every investment case we underwrite — simplified, but not falsified.
Illustrative model. Single-cycle arbitrage only — no ancillary services, capacity payments, degradation, availability or charges included. Real underwriting uses site-specific price curves and a full revenue stack.
Five delivery models, one engineering discipline behind all of them.
Standalone, grid-connected storage sited against congestion, spread and connection availability. We take the asset from land control and pre-licence through to commercial operation.
Solar or wind and storage sharing a single connection point. Higher capacity factor, curtailment recovered, and a materially better use of a scarce grid slot.
Storage placed behind an industrial meter to cut peak demand charges, arbitrage time-of-use tariffs and hold production through a grid event.
Where the grid is weak, expensive or absent. Renewables, storage and controlled generation under one controller, sized against a real load profile rather than a nameplate.
Twelve years of owner's-engineer work carried into storage. Feasibility, technology selection, tender management, independent engineering and lender diligence support.
Most storage projects fail between stages, not inside them. We hold the whole sequence.
Congestion analysis, land, access, and a connection point worth building on.

Illustrative portfolio structure. Project names, sizes and stages to be confirmed prior to publication.
Türkiye is the volume market. Greece and Portugal give the portfolio a second and third price signal — and a hedge against any single regulatory calendar.
Storage is not a subsidy story. It is a volatility story — and volatility is the one thing the energy transition guarantees.
Three layers, deliberately combined. Energy arbitrage takes the daily spread. Ancillary services — frequency response and reserve — pay for availability. Capacity mechanisms, where they exist, put a contracted floor under the merchant tail. Markets that start ancillary-led migrate to arbitrage-led as they saturate; an asset designed for only one of the three ages badly.
Connection capacity, not land or equipment, is now the binding constraint. Every hybrid retrofit and every co-located battery extracts more energy from a connection point that already exists. That scarcity is what protects the asset's position for the next decade.
LFP pricing and cycle life have moved the profitable-arbitrage threshold down year after year. We specify chemistry against the dispatch profile, secure cells with warranty terms that survive diligence, and structure augmentation into the model from day one rather than discovering it in year seven.
The regional pipeline is enormous and the delivered base is tiny. That gap is where returns are made and lost. Our answer is unglamorous: fixed-price EPC where it belongs, contingency where it is real, no schedule we cannot defend line by line to an independent engineer.
Synergist has spent twelve years developing, managing and building photovoltaic projects across Türkiye, Greece and Portugal — consulting, project management, development and EPC, on the owner's side of the table. Storen carries the same people and the same discipline into the part of the system that decides whether all of that generation is worth anything at 19:00 on a still winter evening.
“1 + 1 > 2. Adding value to a project beyond what either party brings alone.”
Both. We develop and co-invest in our own portfolio, and we deliver for third-party owners as developer, EPC contractor or owner's engineer. The engineering standard does not change with the contract structure.
Send us a connection point, a load profile or a pre-licence. We will tell you honestly whether it is worth building.
