Electricity demand is accelerating, but development remains constrained by grid complexity and capital mismatches, particularly in the middle market. We deploy flexible capital for the next buildout of power generation.

Market Context

As electricity demand accelerates and interconnection queues swell, grid access has become the primary bottleneck in U.S. power markets.

Overlay provides capital at this point of constraint, enabling projects to secure and maintain their queue position — capturing value for energy developers.

Strategy Focus

A Structural Inefficiency

Development-stage power projects in the middle market remain structurally underserved. Traditional lenders typically avoid facilities of this size, with shorter durations, and complexity, particularly prior to full construction notice-to-proceed. At the same time, evolving regulatory frameworks and interconnection requirements continue to increase upfront capital needs.

By focusing on this segment, the strategy targets opportunities where pricing reflects perceived complexity rather than fundamental credit risk. This positioning allows us to capture attractive risk-adjusted returns without competing in commoditized construction or permanent capital markets.

Structured for Downside Protection
Risk Profile

Structured for Downside Protection

We deploy capital where collateral resides in tangible project assets, secured development rights, and regulated infrastructure deposits. Transactions are typically over-collateralized and embedded within established recovery or refund mechanisms.

This structural positioning creates differentiated risk exposure relative to merchant energy strategies or conventional construction lending.

Duration & Returns

High Convexity by Design

Predictable yield, controlled duration, and embedded upside participation.

Our loan facilities are generally short-to-medium duration and structured for upside alignment. Beyond current yield, negotiated exit premiums and buyout fees provide return enhancement as projects de-risk and mature, creating asymmetric outcomes relative to downside exposure.

Financing Development-Stage Storage at the Point of Constraint

Overlay Capital provided a $20 million structured bridge facility to Accelergen Energy to fund grid interconnection deposits supporting a 2.6+ GW portfolio of battery storage and hybrid solar + storage projects across WECC and SPP markets. The transaction reflects our energy finance strategy: deploying capital at the critical bottleneck in power development—queue position and interconnection readiness.

Interconnection has become the gating constraint in U.S. power markets. Rising deposit requirements and "first ready, first served" frameworks require developers to demonstrate capital readiness early, making queue position both scarce and timing-sensitive.

Overlay structured a purpose-built development facility that enables Accelergen to maintain and advance queue position while preserving sponsor liquidity and progressing projects toward later-stage financing. This is structured, development-stage infrastructure credit aligned to defined interconnection milestones rather than growth equity.

As electricity demand accelerates, grid access determines which projects ultimately move forward. By financing interconnection deposits, Overlay helps convert development pipelines into future operating infrastructure. Accelergen's analytics-driven siting approach and disciplined portfolio construction make them a strong partner at this stage of the project lifecycle.

Competitive Advantage

Combining grid-market expertise with an active developer ecosystem

Our principals bring deep experience in interconnection mechanics and power project development, enabling disciplined underwriting and early identification of funding needs. Having invested equity and provided loans within the developer ecosystem, we understand the capital sequencing and risk inflection points embedded in modern power asset development.

We operate as a specialized capital partner, not a generalized lender. Our underwriting reflects direct exposure to queue strategy, study risk, network upgrade uncertainty, and deposit structuring. Embedded in the developer ecosystem, we see opportunities forming and understand where capital unlocks value across the power generation lifecycle.
