SEIA backs Massachusetts bill to cut solar costs and speed interconnection
Context and Chronology
Massachusetts’ lower chamber advanced a package of energy reforms framed around affordability, grid access and clean capacity; the bill cleared a key procedural vote this week and now moves toward reconciliation. Stakeholder statements immediately positioned the proposal as a direct lever to accelerate rooftop solar and behind-the-meter storage adoption across the Commonwealth. The trade group SEIA publicly endorsed the measure, highlighting two concrete levers: a statewide permitting platform and a new interconnection service intended to surface unused network headroom. Supporters present these changes as immediate cost mitigants for households while claiming material downstream savings for the state’s energy system.
Operationally, the bill requires standardizing approvals and streamlining technical handoffs that today slow projects and raise soft costs; advocates say better permitting can compress installation timelines and cut customer bills. The design includes mechanisms to identify latent interconnection capacity and repurpose it for new customer-sited resources, a technical approach that, if implemented, reduces queue backlogs and eases distribution-level constraints. Policymakers framed the package as addressing price pressure for ratepayers now while positioning the grid for higher penetrations of variable, distributed generation later. The legislative text is available at malegislature.gov/Bills/194/H5151 for technical review.
Industry reaction centered on quantifiable outcomes: proponents point to an average projected reduction in homeowner solar installation costs and to asserted long-run fiscal benefits totaling multiple billions. These are model-driven claims that depend on rulemaking details and municipal execution timelines; the numbers are meaningful only if permitting, inspection and interconnection reforms are delivered uniformly. Utilities and distribution engineers will hold the operational keys — their implementation choices will determine whether promised capacity is actually unlocked or remains theoretical. Expect an intense negotiation between proponents seeking rapid deployment and system operators focused on safety and hosting limits.
For market participants, the immediate signal is clearer: the Commonwealth is poised to lower deployment friction for distributed solar-plus-storage, which should compress customer acquisition cycles and improve project-level economics. Contractors, platform providers and permitting software vendors could see accelerated demand if the statewide portal standardizes processes and reduces per-project soft costs. Conversely, utilities that must upgrade interconnection workflows face implementation costs and potential schedule exposure. The bill’s passage through the House is a crucial inflection point; the next phase will determine whether legislative intent converts into measurable capacity additions and consumer savings.

Sherrill pushes smart permitting and 3,000 MW community solar to cut New Jersey electricity bills
Governor Mikie Sherrill has ordered accelerated residential and community solar deployment plus temporary bill credits to blunt a near-30% rise in New Jersey utility bills. The strategy pairs permitting reform, a 3,000 MW community-solar registration and state fund transfers while confronting PJM capacity pressures and federal policy headwinds.

Washington moves to bind large data centers to resource and utility protections
Washington’s House passed a bill requiring large data centers (20 MW+) to disclose energy, water, refrigerant use and accept utility tariff terms to prevent cost‑shifting; the measure also phases out free carbon‑credit treatment from 2028 and tightens replacement‑hardware tax breaks, a change tied to about $63 million in new state receipts. The law arrives amid a national pushback — analysts estimate roughly $64 billion in U.S. data‑center projects have been delayed or reshaped by permitting disputes and local resistance — and will push operators and utilities to negotiate staged energization, infrastructure contributions, and other mitigation measures.

SEIA: US Battery Deployments to Reach 70 GWh in 2026, Up 21%
SEIA and Benchmark project US battery installations of about 70 GWh in 2026, a roughly 21% increase versus 2025 driven largely by commercial economics, utility procurement, and solar‑plus‑storage pairing. That demand surge is already prompting OEMs to reallocate factory throughput, new financing into roll‑out players, and international policy shifts — especially China’s reliability‑focused procurement and expanded long‑duration projects — that will reconfigure global supply flows.
Helio Corporation Pushes Space-Based Solar Toward Grid Reliability
Helio and a cluster of startups are framing space-based solar as a credible route to around-the-clock grid reliability, attracting venture capital and national studies. Regulatory, launch-cost, and wireless-transmission hurdles remain, but investor interest and demonstrator missions are compressing timelines for SBSP adoption.

Lunar Energy secures $230 million to scale battery capacity and avert U.S. blackouts
Lunar Energy closed a $230 million financing round to accelerate deployment of grid-scale batteries aimed at reducing blackout risk in the U.S. The capital will expand manufacturing and project rollouts while interacting with shifting global supply-chain dynamics and overseas policy moves that are reshaping demand for stationary storage.

Report: Managed EV Charging Can Significantly Expand Distribution Capacity and Cut Costs
A Brattle-analysed modelling study and accompanying field trial for EnergyHub show that centrally coordinated EV charging can sharply reduce coincident demand and materially increase local hosting capacity, enabling utilities to serve many more vehicles on the same infrastructure while deferring upgrades. Commercial aggregation platforms and bidirectional-capable deployments are starting to bridge this technical capability to real-world procurement and monetization, but interoperability, customer availability, and regulatory compensation will determine realized value.
U.S. Power Mix: Solar Surges as Coal Rises to Fill the Gap
Final EIA 2025 tallies show U.S. electricity demand jumped ~2.8% (≈121 TWh) while combined utility and distributed solar output rose about 35% (≈85 TWh), surpassing annual hydropower — yet solar met only ~two‑thirds of the extra load and a notable rebound in coal and other thermal dispatch filled the remainder. The U.S. pattern mirrors global trends: rapid PV deployment is outpacing transmission and multi‑hour storage builds, creating locational curtailment risks and an urgent need for long‑duration firming to avoid repeat reliance on fossil flexibility.
Residential solar installers pivot to leasing after purchase credit ends
Federal removal of the purchase tax credit has driven rooftop installers to switch from sales to third-party leases, increasing reliance on subscription models and preserving cash flow. This shift raises consumer-protection risks, concentrates economics with financing firms, and pressures local installers to adopt flexible lease offers to survive.
