Registered an energy cooperative but bills keep rising? Here’s why.

Do you remember the wave of enthusiasm surrounding energy cooperatives? When regulations lowered the required threshold for meeting members' energy needs to just 40%, many municipal offices saw it as a ready-made recipe for quick, simple success. All it took was a founding general meeting, registration in the National Court Register (KRS), notification to the National Support Centre for Agriculture (KOWR), and publishing an announcement about a pro-ecological breakthrough in the municipality.
​
However, months pass, and instead of expected savings, unanswered questions arise in many local governments. Finance departments report doubts when settling minor amounts, officials buckle under the weight of new duties, and arrangements with the distribution system operator (DSO) have reached a standstill.
​
Why have so many municipal cooperatives turned into merely "paper projects"? An analysis of implementations to date points to several systemic mistakes that Polish municipalities have fallen into.

1. The Illusion of 40% and the Hidden Cost of the Comprehensive Contract
The biggest trap turned out to be that very tempting, low 40% threshold. Many municipalities established cooperatives based on modest, existing rooftop micro-installations (e.g., 4 sources with a total capacity of approximately 56 kWp). For a municipality consuming 800–1000 MWh annually, such production covers only a fraction of its needs.
​Furthermore, two key financial mechanisms were overlooked:

• Deterioration of conditions for existing photovoltaic installations: Including installations operating under the old, highly profitable net-metering system into a cooperative forces a change in their billing method to net-billing rules, which lowers their previous efficiency.
• The comprehensive contract trap: For an energy cooperative to function, the municipality and its units must switch to a so-called comprehensive contract. Energy prices in such contracts are often higher than in unbundled contracts. If a municipality produces 40% cheaper electricity within the cooperative but has to buy the remaining 60% at a higher rate under the comprehensive contract, the savings from its own production are completely absorbed by the more expensive purchase of the missing energy.

2. The DSO Bottleneck and Administrative Paralysis
Reaching agreements with the Distribution System Operator (DSO) requires highly specialized knowledge in energy law. When this task is assigned to a municipal official alongside their daily, already extensive duties, the process begins to drag out. We know of cases where negotiations lasted over 12 months, which in practice paralyzed the entire project.
​
​Additionally, accounting for very small volumes of energy generates a workload in the municipal office whose cost exceeds the symbolic gains.

In our daily analytical and consulting work, we clearly see that an energy cooperative cannot be a project done "on the side." To yield solid savings, it requires a complete change of approach:

• Shifting perspective from 40% to 70%–90% volume: Real benefits appear only when internal generation covers the vast majority of the demand of the municipality, schools, wastewater treatment plants, and municipal companies.
• Consolidated ground-mounted sources instead of micro-installations: Building one or two dedicated solar farms (e.g., 0.8–1 MWp) on municipal land offers a significantly lower cost of acquiring 1 MWh compared to scattered rooftop installations. Within our network, there are investors ready to invest in such generation sources.
• Model without burdening the municipal budget: An effective structure does not have to mean taking out millions in loans by the municipality. In a properly designed partnership, the municipality can utilize its unused land, gaining lease fees and property tax from structures, while benefiting from cheap energy.
• Interdisciplinary background: The key to navigating DSO procedures efficiently is involving a team combining energy market lawyers, load profile analysts, and engineers.

Here are the 7 most important factors causing municipal energy projects to perform poorly:

1. Basing the project on too low a volume (40%): Building a cooperative on small micro-installations generates symbolic amounts of energy that yield no noticeable savings on a municipal budget scale.
2. Increased cost of purchasing missing energy: Switching to a comprehensive contract (required by law) raises the price of the remaining ~60% of energy purchased from the grid, offsetting the savings generated by the cooperative.
3. Difficulties in relations with the DSO: A lack of specialized legal and energy market expertise on the municipality's side extends negotiations with the grid operator up to a dozen or more months.
4. Deterioration of billing for existing installations: Including installations settled under the old, advantageous net-metering system into the cooperative degrades their economic indicators.
5. Scattered and expensive rooftop infrastructure: Attempts to build multiple small rooftop installations are technically more challenging and more expensive per 1 kWp than building a dedicated ground-mounted solar farm.
6. Overburdening administration and accounting: The complex process of accounting for tiny amounts of energy imposes duties on officials whose administrative cost exceeds the savings generated.
7. Lack of investment funds and grants: Dedicated power sources require capital expenditure (approx. PLN 2.5 million per 1 MWp). Without a well-thought-out external financing model, municipalities fear burdening their budgets with loans.
